+# Feature Analysis: /Users/ullrich/Projects/trails
+
+Analysis of the older trails Remix app for features and patterns that could be
+ported or adapted for trails-cool. Organized by category with implementation
+references.
+
+## Social Features
+
+### Reactions/Kudos System
+Allow users to react to activities with configurable reaction types (currently
+"kudos"). Generic implementation supports any target type (profile, activity,
+etc.). UI shows reaction counts on activity cards.
+
+- `drizzle/models/social-interactions.ts`
+- `app/routes/api+/activities.$activityId.reactions.ts`
+
+### Comments/Replies
+Thread-based comment system on activities. Comments stored as social
+interactions with "reply" kind. Shows reply counts alongside reactions.
+
+- `app/routes/api+/activities.$activityId.replies.ts`
+- `app/routes/feed.tsx`
+
+### User Following
+Follow/unfollow user profiles with mutual follow tracking and uniqueness
+constraints. Can be extended to follow specific routes or activities.
+
+- `app/routes/api+/follows.ts`
+- `app/utils/social.server.ts`
+
+### Personalized Activity Feed
+Feed showing activities from followed users, filtered by visibility (public,
+followers-only, private). Shows interaction counts (reactions, replies).
+
+- `app/routes/feed.tsx`
+- `app/utils/social.server.ts`
+
+## Import & Integration
+
+### Activity Import from External Services
+Komoot integration for importing tours. Batch import tracking with status
+(queued, running, completed, failed). Automatic deduplication using dedupeKey
+prevents duplicate imports. Detailed statistics (totalFound, importedCount,
+duplicateCount).
+
+- `app/inngest/importActivities.ts`
+- `app/utils/integrations.server.ts`
+
+### Third-Party Sync Jobs
+Background Inngest jobs for syncing external platforms. Handles credential
+validation and error recovery. Tracks lastSyncedAt for incremental syncing.
+
+- `app/inngest/komootSync.ts`
+
+### Integration Connections Management
+Store encrypted credentials for multiple service integrations. Track connection
+status and last sync time. Support for multiple users connecting the same
+integration independently.
+
+- `app/routes/integrations.tsx`
+- `app/routes/api+/integrations.ts`
+
+## Route Planning
+
+### Ride Plan Scheduling
+Schedule rides with timezone-aware start/end times. Privacy levels
+(followers-only, private, public). Group ride flag for collaborative planning.
+
+- `drizzle/models/ride-plans.ts`
+
+### Route Geometry Encoding
+Encoded polyline storage for efficient geometry. Route metrics: distance,
+elevation gain, origin, destination. Multiple routes per ride plan.
+
+- `drizzle/models/ride-routes.ts`
+- `app/components/ride-plans/route-editor.tsx`
+
+### Ride Plan Participants
+Invite users to group rides. Track participation status (invited, accepted,
+declined). Enables collaborative ride planning.
+
+- `drizzle/models/ride-plan-participants.ts`
+
+## Activity Tracking
+
+### Live Activity Recording
+Start/pause/finish live recordings. Records start time, end time, duration,
+distance, elevation gain. Manual form completion for recorded activities.
+Activity status tracking (recording, paused, completed).
+
+- `app/components/activities/activity-recorder.tsx`
+- `app/routes/api+/activities.recordings.start.ts`
+
+### Activity Visibility Levels
+Public, followers-only, and private visibility options. Source tracking (native
+recording vs. import). Link activities to specific ride plans and routes.
+
+- `drizzle/models/ride-activities.ts`
+
+## User Profile & Content
+
+### Profile Images
+S3-compatible storage for profile pictures. Signed PUT requests for direct
+client uploads. Image serving via openimg library for optimization.
+
+- `app/utils/storage.server.ts`
+- `drizzle/models/user-images.ts`
+
+### User Notes/Blog
+Rich note creation with title and markdown content. Image attachments to notes
+(up to 5 images per note). Note listing and detail views. Image form validation
+(3MB max per file).
+
+- `drizzle/models/notes.ts`
+- `app/routes/users+/$username_+/notes.tsx`
+
+### Note Images
+Upload and manage images within notes. Alt text support for accessibility. S3
+storage with organized paths.
+
+- `drizzle/models/note-images.ts`
+- `app/routes/users+/$username_+/__note-editor.tsx`
+
+## Search & Discovery
+
+### User Search
+Full-text search over username and display name. Pagination with limit of 50
+results. Search results with profile images. Case-insensitive matching.
+
+- `app/routes/users+/index.tsx`
+
+### Search Bar Component
+Debounced auto-submit search. Reusable search UI component. Query parameter
+preservation.
+
+- `app/components/search-bar.tsx`
+
+## Authentication & Settings
+
+### Two-Factor Authentication
+TOTP-based 2FA on top of passkeys. Settings UI for enabling/disabling.
+Verification flow.
+
+- `app/routes/settings+/profile.two-factor.tsx`
+
+### Email Verification
+Email-based account verification. Verification token tracking. Email change
+flow with verification.
+
+- `drizzle/models/verifications.ts`
+
+### Profile Management
+Change email, password, name. Photo upload. Passkey management. Connected
+OAuth providers (GitHub).
+
+- `app/routes/settings+/profile.tsx`
+
+## Federation
+
+### ActivityPub Foundation
+Inbox/outbox endpoints for federated social network. Background publishing via
+Inngest. Federation record tracking for local/federated entity mapping.
+
+- `app/routes/api+/activitypub.inbox.ts`
+- `app/routes/api+/activitypub.outbox.ts`
+
+## Data Management
+
+### Activity Files Association
+Attach files/media to activities. Track file metadata and relationships.
+
+- `drizzle/models/activity-files.ts`
+
+### Import Batch Tracking
+Comprehensive import job tracking. Status lifecycle: queued, running,
+completed, failed. Timing and statistics per batch. Progress monitoring in UI.
+
+- `drizzle/models/import-batches.ts`
+
+## Architectural Patterns
+
+### Role-Based Access Control
+User roles and permission system. Basis for admin controls. Permission groups
+for feature access.
+
+- `drizzle/models/roles.ts`
+- `drizzle/models/permissions.ts`
+
+### Background Job Queue (Inngest)
+Event-driven async processing. Reliable job retry with exponential backoff.
+Step-based workflow for complex operations. Progress monitoring and error
+handling.
+
+- `app/inngest/`
+
+### Deduplication Strategy
+Unique composite keys (ownerId + dedupeKey) for imports. onConflictDoNothing
+pattern prevents duplicates. Useful for imports from multiple sources.
+
+- `drizzle/models/ride-activities.ts`
+
+## UX/Component Patterns
+
+### Status Button
+Button that displays async operation states (idle, pending, success, error).
+Useful for form submissions and API calls.
+
+- `app/components/ui/status-button.tsx`
+
+### Form Validation (Conform + Zod)
+Client/server validation with Conform.js and Zod. Constraint generation from
+schemas. Field error display and form recovery.
+
+- `app/components/forms.tsx`
+
+## Priority Suggestions for trails-cool
+
+**High (directly applicable):**
+- Reactions/Kudos — simple engagement, minimal schema
+- Comments — essential social feature
+- Following — core for Phase 2 federation
+- Live Activity Recording — core outdoor feature
+- User Search — discovery
+
+**Medium (enhances existing):**
+- Profile images — user experience
+- Activity visibility levels — privacy controls
+- Import from Komoot/Strava — integration value
+- Ride plan participants — collaborative planning
+
+**Lower (future):**
+- Notes/Blog — content creation
+- 2FA — security hardening
+- Role-based access — admin features
+- Background jobs (Inngest pattern) — already have infra for it

+## Context
+
+Navigation audit found: Journal's `/routes` and `/activities` pages are
+orphaned (no links point to them). The Planner home page has no CTA. Logout
+is only on the profile page. Users must know URLs to use the apps.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Every non-API route reachable via UI navigation
+- Logged-in Journal users see: Routes, Activities, profile, logout
+- Logged-out Journal users see: login, register
+- Planner home has a clear "start planning" action
+- Keep it minimal — a thin bar, not a complex sidebar
+
+**Non-Goals:**
+- Mobile hamburger menu (responsive PR already hides sidebar — nav bar wraps naturally)
+- Breadcrumbs or nested navigation
+- Settings page (future)
+
+## Decisions
+
+### D1: Journal nav bar in root Layout
+
+Add a `<nav>` element inside `Layout` in `root.tsx`. The root loader already
+returns the user (added for Sentry context), so the nav bar can conditionally
+show authenticated vs. unauthenticated links. No new loader needed.
+
+### D2: Planner gets a CTA on home, not a nav bar
+
+The Planner is session-focused — users arrive, create a session, and work in
+it. A full nav bar would be overhead. Instead: home page gets a prominent
+"Start Planning" button linking to `/new`. Session view already has a header —
+add a small logo/home link to it.
+
+### D3: Use @trails-cool/ui for shared nav component
+
+The nav bar itself is Journal-specific (routes, activities, auth). No need
+to put it in the shared UI package — it goes directly in Journal's root.tsx
+or a colocated component.

+## Why
+
+Both apps have pages that are only reachable by typing URLs. The Journal has no
+navigation bar — logged-in users can't find their routes or activities without
+knowing the URLs. The Planner home page is a dead end with no way to create a
+session. This makes the apps unusable for anyone who doesn't know the URL
+structure.
+
+## What Changes
+
+- **Journal**: Add a navigation bar (home, routes, activities, profile, logout)
+  that appears when logged in. Unauthenticated users see login/register links.
+- **Planner**: Add a "New Session" CTA on the home page. Add a minimal header
+  in session view with a link back to home.
+- Both apps get consistent, minimal navigation that makes all features
+  discoverable.
+
+## Capabilities
+
+### New Capabilities
+
+(None — this adds UI chrome to existing features, no new behavioral capabilities.)
+
+### Modified Capabilities
+
+- `map-display`: Planner home page gains a CTA and session header gains a home link
+
+## Impact
+
+- **Files**: Journal `root.tsx` (nav bar), Planner `home.tsx` (CTA),
+  Planner `SessionView.tsx` (home link), new `NavBar` component
+- **Dependencies**: None
+- **i18n**: New translation keys for navigation labels

+## MODIFIED Requirements
+
+### Requirement: Planner home page
+The Planner home page SHALL provide a clear call-to-action to create a new planning session and a link back to the home page from within sessions.
+
+#### Scenario: Home page CTA
+- **WHEN** a user visits the Planner home page
+- **THEN** a prominent "Start Planning" button is visible that links to `/new`
+
+#### Scenario: Session home link
+- **WHEN** a user is in a planning session
+- **THEN** the header contains a link back to the Planner home page

+## Context
+
+trails.cool ships features regularly but has no user-facing changelog. The
+project philosophy values transparency and simplicity. We need a changelog
+that's low-friction to write (just add a markdown file), works in-app, and
+produces shareable social links.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Zero-friction authoring: drop a `.md` file, deploy, done
+- Public page at `/changelog` listing all entries newest-first
+- Individual entry pages at `/changelog/:slug` with OG meta for social sharing
+- "What's New" indicator in nav for returning users
+- Works without JavaScript (SSR)
+
+**Non-Goals:**
+- CMS or admin interface for writing entries
+- RSS feed (future, not now)
+- Email notifications for new entries
+- Per-entry images or rich media (just markdown text)
+- Bilingual entries (English only for now)
+
+## Decisions
+
+### D1: Markdown files in the repo, loaded at build time
+
+Changelog entries live in `apps/journal/changelog/` as markdown files named
+by date: `2026-03-25.md`. Vite's `import.meta.glob` loads them at build time.
+No runtime file system access needed.
+
+Each file has YAML frontmatter:
+
+```yaml
+---
+title: "Collaborative route planning goes live"
+date: 2026-03-25
+---
+```
+
+### D2: Single route with dynamic slug
+
+`/changelog` shows all entries. `/changelog/:date` shows a single entry.
+Both are one route file using an optional param or two route files. The list
+page shows titles + dates + first paragraph preview.
+
+### D3: "What's New" via localStorage timestamp
+
+Store `changelog:lastSeen` timestamp in localStorage. If the newest entry's
+date is after this timestamp, show a dot on the nav "Changelog" link. Clicking
+the changelog page updates the timestamp. No server state needed.
+
+### D4: Open Graph meta for social sharing
+
+Each `/changelog/:date` page sets `og:title`, `og:description` (first
+paragraph), and `og:url`. No og:image for now — text previews are fine.
+
+## Risks / Trade-offs
+
+- **Build-time loading means deploy to publish** → Acceptable. We deploy on
+  every merge to main. Adding a changelog entry is: write file, PR, merge,
+  deployed.
+- **No rich media** → Keeps it simple. Can add images later if needed.
+- **localStorage "what's new" doesn't sync across devices** → Fine for now.
+  Server-side tracking would require auth and a DB table — overkill.

+## Why
+
+We ship features but nobody knows. There's no record of what changed, no way to
+share progress, and no way for users to discover new features. A changelog
+serves three audiences: existing users (what's new), potential users (the
+project is alive and improving), and social followers (shareable updates).
+
+## What Changes
+
+- Add a `/changelog` page in the Journal showing dated entries with feature
+  descriptions
+- Changelog entries stored as markdown files in the repo (not a database) —
+  low friction, version controlled, works with the PR workflow
+- Each entry renders as a standalone shareable page (`/changelog/2026-03-25`)
+  with Open Graph meta tags for social previews
+- A "What's New" badge/dot on the nav bar when there are entries the user
+  hasn't seen
+- The changelog is public (no auth required) — it's part of the product's
+  public face
+
+## Capabilities
+
+### New Capabilities
+
+- `changelog`: Public changelog with dated entries, shareable individual pages with OG tags, "what's new" indicator
+
+### Modified Capabilities
+
+(None)
+
+## Impact
+
+- **Files**: New routes (`/changelog`, `/changelog/:slug`), markdown entry files
+  in `docs/changelog/` or `apps/journal/changelog/`, nav bar update
+- **Dependencies**: A markdown renderer (could reuse `react-markdown` or render
+  at build time)
+- **i18n**: Changelog entries written in English (primary audience), German
+  later if needed

+## Context
+
+trails.cool Journal supports manual route creation and GPX import. Users coming
+from Komoot have hundreds of tours they'd lose by switching. The old trails
+project had a working Komoot integration using basic auth against Komoot's
+undocumented API (`api.komoot.de`).
+
+## Goals / Non-Goals
+
+**Goals:**
+- Connect Komoot account via email + password
+- Import all tours (paginated) as activities + routes
+- Track import progress with batch status
+- Deduplicate on re-import (same tour never imported twice)
+- Fetch GPX geometry per tour (not just metadata)
+
+**Non-Goals:**
+- OAuth flow (Komoot has no public OAuth — basic auth only)
+- Real-time sync or webhook-based updates
+- Strava/other providers (future iteration, but design the schema generically)
+- Background job queue like Inngest (keep it simple — synchronous import with progress)
+
+## Decisions
+
+### D1: Generic integrations table with provider column
+
+Store connections in a `journal.integrations` table with a `provider` enum
+(`komoot`, and later `strava` etc). Credentials encrypted at rest. This avoids
+a separate table per provider.
+
+### D2: Import batches for progress tracking
+
+Each import creates an `import_batches` row tracking: status (running,
+completed, failed), total found, imported count, duplicate count, error message.
+The UI polls this for progress.
+
+### D3: Deduplication via composite key
+
+Activities get a `dedupeKey` column. For Komoot: `komoot:{tourId}`. Combined
+with `ownerId`, a unique constraint prevents duplicates. Insert uses
+`onConflictDoNothing`.
+
+### D4: Synchronous import with streaming progress
+
+No background job queue. The import runs in an API route action that:
+1. Fetches all tour pages from Komoot
+2. For each tour, fetches GPX and creates activity + route
+3. Updates the batch row with progress
+4. Client polls `/api/integrations/komoot/import-status` for live updates
+
+This keeps the architecture simple. If imports are too slow (>100 tours), we
+can add a background worker later.
+
+### D5: Encrypt credentials with AES-256-GCM
+
+Use Node's `crypto.createCipheriv` with a server-side key derived from
+`INTEGRATION_SECRET` env var. Decrypt on use, never log plaintext.
+
+**Alternative considered**: Store only the API token (not email+password).
+Rejected because the token may expire and re-auth requires the original
+credentials.
+
+## Risks / Trade-offs
+
+- **Komoot API is undocumented** → Could break without notice. Mitigation: wrap
+  all API calls in error handling, mark integration as "needs reauth" on 401.
+- **Storing user passwords for third-party service** → Security risk.
+  Mitigation: AES-256-GCM encryption, separate `INTEGRATION_SECRET`, document
+  in privacy manifest.
+- **Synchronous import may timeout for large accounts** → Mitigation: paginate
+  and commit per-page. If a page fails, the batch is marked partial and can be
+  resumed.

+## Why
+
+Users switching to trails.cool have years of tours on Komoot. Without import,
+they start with an empty Journal — no history, no motivation to switch. A
+one-click Komoot import lets users bring their existing tours and start using
+trails.cool immediately.
+
+## What Changes
+
+- Add Komoot account connection flow (email + password → API credentials)
+- Import Komoot tours as Journal activities with route data
+- Batch import with progress tracking, deduplication, and error handling
+- Integration settings page to manage connected accounts and trigger imports
+- Fetch full tour GPX (not just metadata) so imported routes have geometry
+
+## Capabilities
+
+### New Capabilities
+
+- `komoot-import`: Connect a Komoot account, import tours as activities with routes, track import progress, deduplicate on re-import
+
+### Modified Capabilities
+
+- `route-management`: Routes can now be created via import (not just manual creation), with an external source tracking field
+
+## Impact
+
+- **Database**: New tables for integration connections and import batches in `journal` schema
+- **Files**: New routes (`/integrations`, `/api/integrations/*`), new server utilities for Komoot API, new DB schema tables
+- **Dependencies**: No new packages needed — uses fetch for Komoot API, existing Drizzle for DB
+- **Privacy**: Komoot credentials stored encrypted. Must be documented in privacy manifest.
+- **External**: Komoot API (api.komoot.de) — basic auth, no official developer program

+## Context
+
+The Planner architecture defines noGoAreas, notes, and crash recovery in the
+Yjs data model but none are implemented. The public instance also lacks rate
+limiting — anyone can create unlimited sessions or hammer BRouter.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Draw no-go polygons on the map, synced via Yjs, sent to BRouter
+- Shared notes (Y.Text) visible in sidebar for planning discussion
+- localStorage backup of Yjs state, merged on reconnect
+- Rate limits: 10 sessions/IP/hour, 60 BRouter calls/session/hour
+
+**Non-Goals:**
+- Complex polygon editing (holes, multi-polygon) — just simple polygons
+- Rich text in notes (just plain text)
+- Cross-tab Yjs sync via localStorage (handled by WebSocket)
+- Rate limiting dashboard or admin UI
+
+## Decisions
+
+### D1: No-go areas as Yjs Y.Array of polygon coordinates
+
+```typescript
+// Yjs doc structure addition
+noGoAreas: Y.Array<Y.Map<{
+  points: Array<{lat: number, lon: number}>,
+  name?: string
+}>>
+```
+
+Each polygon is a closed ring of lat/lon points. BRouter accepts no-go areas
+as a `nogo` parameter: `lon,lat,radius` for circles or polygon coordinates
+depending on the BRouter version. We'll convert our polygons to BRouter's
+expected format in the routing request.
+
+### D2: Leaflet.draw for polygon drawing
+
+Use `leaflet-draw` (or `@geoman-io/leaflet-geoman-free`) for drawing polygons
+on the map. When a polygon is completed, add it to the Y.Array. Existing
+polygons render as semi-transparent red overlays.
+
+### D3: Notes as Y.Text in sidebar tab
+
+Add a "Notes" tab to the sidebar (alongside waypoints). Uses Y.Text for
+collaborative editing — simple textarea bound to Y.Text. Changes sync in
+real-time. No markdown rendering — plain text only.
+
+### D4: localStorage crash recovery
+
+Every 10 seconds, save `Y.encodeStateAsUpdate(doc)` to
+`localStorage['trails:session:${id}']`. On page load, if localStorage has
+state for the current session, apply it as an update before connecting to
+the server. Yjs CRDTs merge automatically — no conflicts.
+
+Clear localStorage entry when session is closed or after successful sync.
+
+### D5: In-memory rate limiter
+
+Simple Map-based rate limiter in `server.ts`:
+- Session creation: Track IP → count + window. Reject with 429 after 10/hour.
+- BRouter proxy: Track session ID → count + window. Reject after 60/hour.
+- No Redis needed — single server, in-memory is fine. Resets on restart
+  (acceptable).
+
+## Risks / Trade-offs
+
+- **leaflet-draw adds bundle size** → ~50KB gzipped. Acceptable for polygon
+  drawing functionality. Can lazy-load.
+- **localStorage size limit** → ~5MB per origin. Yjs state is typically
+  10-100KB. No risk.
+- **In-memory rate limiter resets on deploy** → Acceptable for current scale.
+  Redis-backed when needed.

+## Why
+
+The Planner's core editing works but is missing features from the architecture
+doc: no-go areas for route avoidance, session notes for collaborative planning
+communication, localStorage crash recovery for unsaved work, and rate limiting
+to protect the BRouter API from abuse on the public instance.
+
+## What Changes
+
+- **No-go areas**: Draw polygons on the map that BRouter avoids when computing
+  routes. Stored as Y.Array in the Yjs doc, synced across participants.
+- **Session notes**: Shared text area (Y.Text) for participants to leave notes,
+  discuss the route, or plan logistics. Visible in the sidebar.
+- **Crash recovery**: Periodically save Yjs state to localStorage. On
+  reconnect, merge local state with server state to recover unsaved changes.
+- **Rate limiting**: Limit session creation per IP and BRouter API calls per
+  session to prevent abuse on the public instance.
+
+## Capabilities
+
+### New Capabilities
+
+- `no-go-areas`: Draw avoidance polygons on the Planner map, passed to BRouter as routing constraints
+- `session-notes`: Shared collaborative text in Planner sessions via Yjs Y.Text
+- `crash-recovery`: localStorage backup of Yjs state for reconnection after browser crash
+- `rate-limiting`: IP-based limits on session creation and route computation
+
+### Modified Capabilities
+
+- `planner-session`: Session data model gains noGoAreas and notes fields
+- `brouter-integration`: Routing requests include no-go area polygons
+- `map-display`: Map gains polygon drawing tools for no-go areas
+
+## Impact
+
+- **Planner Yjs doc**: New fields (noGoAreas: Y.Array, notes: Y.Text)
+- **BRouter API**: No-go areas passed as `nogo` parameter
+- **Map**: Leaflet.draw or custom polygon tool for no-go areas
+- **Dependencies**: May need `leaflet-draw` for polygon editing
+- **Server**: Rate limiting middleware (in-memory store)

+## Context
+
+The Planner home page is currently a centered heading ("trails.cool Planner")
+and subtitle. It has no CTA, no explanation, and no way to start. Users must
+know to visit `/new` to create a session.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Explain what the Planner does in 5 seconds of reading
+- One-click session creation (no signup, no form)
+- Feature highlights: collaborative, BRouter routing, elevation, GPX export
+- Link to Journal for users who want accounts and saved routes
+- i18n (English + German)
+- Fast load, SSR-friendly, no heavy JS
+
+**Non-Goals:**
+- Marketing copy or elaborate graphics
+- Pricing or plans
+- User testimonials
+- Interactive map demo on the landing page (too heavy)
+
+## Decisions
+
+### D1: Single-page component in home.tsx
+
+No new route — rewrite `apps/planner/app/routes/home.tsx`. The page is static
+content + a CTA link to `/new`. No loader needed.
+
+### D2: Feature cards with icons
+
+Show 4-5 feature highlights as simple cards: collaborative editing, route
+profiles, elevation profile, GPX export, no account needed. Use Tailwind —
+no icon library, just emoji or simple SVG.
+
+### D3: Link to Journal as secondary CTA
+
+"Want to save your routes? Create a free account on trails.cool" — links to
+the Journal. This bridges the two apps without requiring Journal for basic use.
+
+### D4: Footer with legal and links
+
+Privacy link (points to Journal's /privacy), GitHub repo, "Built with
+BRouter and OpenStreetMap" attribution.

+## Why
+
+The Planner at planner.trails.cool should work as a standalone product — anyone
+can visit, understand what it does, and start planning a route without needing
+the Journal. Currently the home page is a blank heading with no explanation and
+no way to start. Visitors bounce immediately.
+
+## What Changes
+
+- Replace the Planner home page with a landing page that explains the tool:
+  collaborative route planning, BRouter routing, GPX export, no account needed
+- Prominent "Start Planning" CTA that creates a new session
+- Brief feature highlights (collaborative editing, routing profiles, elevation,
+  GPX export)
+- Footer with links to trails.cool Journal, privacy page, GitHub repo
+- The landing page should load fast — no heavy assets, SSR-friendly
+
+## Capabilities
+
+### New Capabilities
+
+(None — this replaces an existing page with useful content.)
+
+### Modified Capabilities
+
+- `planner-session`: Home page becomes a landing page with session creation CTA
+- `map-display`: Landing page may show a decorative map or screenshot
+
+## Impact
+
+- **Files**: `apps/planner/app/routes/home.tsx` (complete rewrite), i18n keys
+- **Dependencies**: None
+- **Design**: Needs to look good — this is the first impression for standalone
+  Planner users

+## Context
+
+Yjs awareness already tracks users with `{ color, name }` state and renders
+map cursors via `CursorTracker` in `PlannerMap.tsx`. The current implementation
+has issues: random names can't be changed, cursor labels are unstyled, and
+there's no participant list showing who's in the session.
+
+## Goals / Non-Goals
+
+**Goals:**
+- See all participants in the session (name, color, host/participant role)
+- Edit your own name (saved to localStorage, synced via awareness)
+- Polished cursor rendering on the map
+- Visual feedback when someone joins or leaves
+
+**Non-Goals:**
+- Chat or messaging between participants
+- Cursor position sharing outside the map (e.g., in the sidebar)
+- Participant permissions or kicking (admin-only debug feature already exists)
+
+## Decisions
+
+### D1: Participant list in session header
+
+Show colored dots + names in the header bar (already has space between profile
+selector and connection status). Clicking your own name opens an inline edit.
+Keeps the sidebar free for waypoints.
+
+### D2: Name persisted in localStorage, synced via awareness
+
+Current approach: random name from a list, stored in localStorage as
+`trails:user`. Enhancement: let users edit it. On change, update localStorage
+AND call `awareness.setLocalStateField("user", { color, name })`. All other
+clients see the update immediately.
+
+### D3: Cursor as SVG pointer with name tag
+
+Replace the current `divIcon` cursor label with: a small SVG arrow in the
+user's color + a name tag with background, shadow, and rounded corners.
+Position offset so the pointer tip is at the actual lat/lng.
+
+### D4: Join/leave toasts
+
+When awareness detects a new client or a client leaving, show a brief toast
+("Alice joined" / "Bob left") that auto-dismisses after 3 seconds. Use a
+simple absolute-positioned div, no toast library.

+## Why
+
+The Planner supports collaborative editing but the multiplayer experience is
+bare. Users can't see who else is in the session. Cursor labels are small
+floating divs that look broken (no proper styling, overlap with map controls).
+Users get randomly assigned names like "Hiker" or "Explorer" with no way to
+change them. This makes collaboration confusing — you can't tell who is who.
+
+## What Changes
+
+- **Participant list**: Show who's in the session (name, color, host badge)
+  in the sidebar or header
+- **Name editing**: Let users set their name after joining (persisted in
+  localStorage, synced via Yjs awareness)
+- **Cursor styling**: Fix cursor labels — proper pointer icon, name tag with
+  shadow, avoid overlap with map controls
+- **Connection indicators**: Show when participants join/leave

+## Context
+
+The architecture doc defines a rich route model with permissions, multi-day
+support, spatial queries, and photos. Currently routes are owner-only, flat
+(no days), and have no photos or spatial search. This change adds the route
+and activity features needed before federation makes them visible to others.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Route visibility (private/public) and sharing with specific users
+- Fork public routes
+- Multi-day route support with day-break waypoints
+- Map-based route discovery via PostGIS
+- Photo attachments on activities
+- Contributor tracking on route versions
+
+**Non-Goals:**
+- Federation of routes (separate change)
+- Real-time collaborative permission changes
+- Photo editing or filters
+- Route recommendations based on preferences
+- Activity collections (multi-day trip grouping — future)
+
+## Decisions
+
+### D1: Visibility as enum column on routes and activities
+
+Add `visibility` column (`public`, `private`, default `private`) to both
+routes and activities. `followers_only` added later when following exists.
+Public routes appear in spatial search. Private routes are owner-only.
+
+### D2: Route shares table for explicit sharing
+
+```
+journal.route_shares (routeId, userId, permission: 'view' | 'edit')
+```
+
+Owner can share with specific users. Shared users see the route in their
+"Shared with me" section. Edit permission allows starting Planner sessions.
+
+### D3: Day breaks as waypoint property
+
+The Planner's Yjs waypoint Y.Map gets an optional `isDayBreak: true` field.
+The sidebar and elevation chart show day boundaries. GPX export uses one
+track segment per day. The Journal stores day-break indices in route metadata.
+
+### D4: PostGIS spatial search
+
+Routes already store geometry as PostGIS LineString. Add a `/routes/explore`
+page with a map — as the user pans/zooms, query public routes within the
+bounding box using `ST_Intersects`. Show route previews on the map.
+
+### D5: Photo storage via S3 (Garage)
+
+Use the Garage S3-compatible storage already in the architecture. Upload flow:
+server generates presigned PUT URL → client uploads directly to S3 → server
+stores the S3 key in a `journal.activity_photos` table. Serve via presigned
+GET URLs or a CDN path.
+
+### D6: Contributor tracking via array column
+
+Add `contributors` text array to `journal.route_versions`. When a Planner
+session saves back via callback, the JWT identifies the actor. The version
+records the contributor's user ID (or ActivityPub URI for future federation).
+
+## Risks / Trade-offs
+
+- **S3 setup required** → Garage needs to be enabled in docker-compose (currently commented out). Adds operational complexity.
+- **Spatial search performance** → PostGIS bounding box queries are fast with spatial indexes. Already have the geometry column.
+- **Multi-day in Planner requires Yjs changes** → Adding `isDayBreak` to waypoints is backward-compatible (optional field). Existing sessions unaffected.

+## Why
+
+Routes are currently flat — no permissions beyond owner, no way to share with
+specific people, no forking, no multi-day support, no spatial discovery, and
+no contributor tracking. The architecture doc specifies all of these for Phase
+2. Without them, routes are just personal GPX storage with no social or
+collaborative dimension.
+
+## What Changes
+
+- **Route sharing permissions**: Private/public/shared visibility levels with
+  a view/edit permission matrix
+- **Route forking**: Copy someone else's public route to your own collection
+- **Multi-day routes**: Day-break waypoints that split a route into stages with
+  per-day stats and GPX segments
+- **Spatial search**: "Routes near me" or "routes in this area" using PostGIS
+- **Contributor tracking**: Record who contributed to each route version
+- **Activity visibility levels**: Public/followers-only/private on activities
+- **Photo attachments**: Upload photos to activities (requires S3/Garage setup)
+
+## Capabilities
+
+### New Capabilities
+
+- `route-sharing`: Permission model (private/public/shared), view/edit access, route forking
+- `spatial-search`: Map-based route discovery using PostGIS bounding box and proximity queries
+- `multi-day-routes`: Day-break markers on waypoints, per-day stats, multi-segment GPX export
+- `activity-photos`: Photo upload and display on activities via S3-compatible storage
+
+### Modified Capabilities
+
+- `route-management`: Add visibility, contributor tracking, forking
+- `activity-feed`: Add visibility levels (public/followers-only/private)
+- `planner-session`: Support day-break waypoint markers
+- `infrastructure`: S3/Garage setup for photo storage
+
+## Impact
+
+- **Database**: New columns (visibility, contributors) on routes and activities, new route_shares table, photo storage metadata
+- **Storage**: S3-compatible object storage (Garage) for photos
+- **Files**: Route detail page, activity pages, search page, Planner waypoint UI, sharing UI
+- **Dependencies**: S3 client library for photo uploads
+- **Privacy**: Photo storage, route visibility controls documented in manifest

+## Context
+
+The Journal has passkey auth (primary) and magic link login (fallback). Magic
+links work in dev (auto-redirect) but in production the link is only logged
+to console — users never receive it. No email infrastructure exists.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Actually deliver magic link emails in production
+- Send a welcome email after registration
+- Provider-agnostic email interface (easy to swap providers)
+- HTML templates with plain-text fallback
+- Easy to add new email types in the future (just add a template + call)
+- Dev mode: still log to console / return devLink (no real emails)
+
+**Non-Goals:**
+- Marketing emails or newsletters
+- Email preferences / unsubscribe (only transactional)
+- Inline CSS / complex email layouts (keep it simple text-focused)
+- Queuing or retry logic (provider handles delivery)
+
+## Decisions
+
+### D1: Resend as email provider
+
+Use [Resend](https://resend.com) — simple API, generous free tier (3k
+emails/month), good developer experience. Single dependency: `resend` npm
+package.
+
+**Alternative considered**: Nodemailer + SMTP. More complex setup, requires
+SMTP server. Resend is simpler for a small project.
+
+**Alternative considered**: Postmark. Similar to Resend but less ergonomic API.
+
+### D2: Email module in apps/journal/app/lib/email.server.ts
+
+Not a shared package — only the Journal sends emails. Keep it simple:
+- `sendEmail(to, subject, html, text)` — low-level sender
+- `sendMagicLink(email, link)` — template wrapper
+- `sendWelcome(email, username)` — template wrapper
+
+In dev mode, `sendEmail` logs to console instead of calling Resend.
+
+### D3: Inline HTML templates
+
+Simple functions returning HTML strings. No template engine. Each email type
+is a function: `magicLinkTemplate(link)`, `welcomeTemplate(username)`. Plain
+text generated by stripping tags.
+
+### D4: Sender domain: noreply@trails.cool
+
+Requires DNS verification (DKIM/SPF records) with Resend. Add TXT records via
+Terraform or manually in Hetzner DNS.
+
+## Risks / Trade-offs
+
+- **Resend vendor lock-in** → Low risk. The `sendEmail` wrapper abstracts it.
+  Swapping to nodemailer later is a one-file change.
+- **DNS verification required** → Must add DKIM/SPF records before emails work.
+  Can use Resend's test domain initially.
+- **Free tier limits** → 3k/month is plenty for <100 users.

+## Why
+
+Magic link login doesn't work in production — the link is logged to console
+but never emailed to the user. Registration works (passkey-based) but the
+fallback auth flow is broken. We need actual email delivery.
+
+## What Changes
+
+- Add a reusable email sending layer (`@trails-cool/email` or in-app module)
+  with a provider-agnostic interface so future emails are trivial to add
+- Send magic link emails in production
+- Send a welcome email after registration
+- Use a transactional email provider (Resend, Postmark, or SMTP)
+- HTML email templates with plain-text fallback
+- Document email sending in the privacy manifest
+
+## Capabilities
+
+### New Capabilities
+
+- `transactional-emails`: Send templated emails via a provider-agnostic interface. Current emails: magic link login, welcome on registration. Designed for easy addition of future email types.
+
+### Modified Capabilities
+
+- `journal-auth`: Magic link flow now actually sends the email instead of logging to console
+
+## Impact
+
+- **Files**: New email module (lib or package), modified `api.auth.login.ts`, modified registration flow, email templates
+- **Dependencies**: One email provider SDK (e.g., `resend` or `nodemailer`)
+- **Infrastructure**: Email provider API key as env var, DNS records for sender domain verification
+- **Privacy**: Email addresses sent to third-party email provider — must document

+## ADDED Requirements
+
+### Requirement: Email sending interface
+The system SHALL provide a provider-agnostic email sending function that supports HTML and plain-text content.
+
+#### Scenario: Send email in production
+- **WHEN** the system sends a transactional email in production
+- **THEN** the email is delivered via the configured provider (Resend) to the recipient
+
+#### Scenario: Dev mode skips sending
+- **WHEN** the system sends a transactional email in development
+- **THEN** the email content is logged to console and no external API is called
+
+### Requirement: Magic link email
+The system SHALL send an email containing the magic link when a user requests passwordless login.
+
+#### Scenario: Magic link delivered
+- **WHEN** a user requests a magic link login
+- **THEN** an email is sent with a clickable link that logs them in
+
+#### Scenario: Email content
+- **WHEN** a magic link email is sent
+- **THEN** it includes: the link, expiry time (15 minutes), and plain-text fallback
+
+### Requirement: Welcome email
+The system SHALL send a welcome email after successful registration.
+
+#### Scenario: Welcome on registration
+- **WHEN** a user completes passkey registration
+- **THEN** a welcome email is sent to their registered email address
+
+### Requirement: Email templates
+Each email type SHALL have an HTML template with a plain-text fallback.
+
+#### Scenario: Extensible template pattern
+- **WHEN** a new email type is needed in the future
+- **THEN** it can be added by creating a template function and calling sendEmail
+
+### Requirement: Privacy disclosure
+Email sending SHALL be documented in the privacy manifest.
+
+#### Scenario: Privacy manifest updated
+- **WHEN** transactional emails are enabled
+- **THEN** the /privacy page documents: what emails are sent, that email addresses are shared with the email provider, and which provider is used
