Ullrich Schäfer f0ef989ac3 Rebuild the Journal home around a public feed and flagship marketing
The old home was an h1, subtitle, and two auth buttons — visitors
arriving at trails.cool had no idea what it was, and self-hosted
instances had nothing interesting to land on.

The new home is one layout that serves both audiences:

- Hero: a product-describing h1 ("Federated outdoor journal") +
  tagline. The site name already lives in the top banner and nav brand,
  so the h1 carries the pitch instead of triplicating "trails.cool".
- Auth CTAs: Register (blue) + Sign In (outlined) get primary weight.
  Planner demotes to a small "Or try the Planner without an account →"
  link below them — it's a nice escape hatch but not the goal.
- Marketing cards: on the flagship only, a 2x2 grid of emoji-icon cards
  for Planner / Journal / Federation / Ownership, matching the Planner
  home's visual weight. `IS_FLAGSHIP=true` toggles it. Self-hosters get
  a "Powered by trails.cool — about the project" link back to the
  flagship instead, so they don't have to write their own marketing.
- Public feed: reverse-chronological list of the 20 most recent public
  activities on the instance, with owner + distance + date. Empty state
  for fresh installs.

Plumbing:
- `listRecentPublicActivities(limit)` in activities.server.ts joins
  users so the feed can render "by <displayName>" in one query.
- `IS_FLAGSHIP` env wired through docker-compose.yml; cd-apps and
  cd-infra both write `IS_FLAGSHIP=true` alongside `DOMAIN=trails.cool`,
  so self-hosters (who deploy without these workflows) default to off.

Specs:
- `activity-feed`: new "Instance-wide public activity feed" requirement
  so the visibility contract is pinned (public in feed, unlisted +
  private are not).
- `journal-landing`: new small spec capturing the hero / marketing /
  feed layout contract and the `IS_FLAGSHIP` toggle, so future
  instance-branding or empty-state changes have a stable anchor.

## Purpose
Activity creation, chronological feed, detail views, and route linking in the Journal app.
## Requirements
### Requirement: Create activity
The Journal SHALL allow authenticated users to create an activity by uploading a GPX trace and adding a description.
#### Scenario: Create activity with GPX
- **WHEN** a user uploads a GPX file and enters a description
- **THEN** an activity is created with the GPS trace, computed distance and duration, and stored in the database
#### Scenario: Create activity linked to route
- **WHEN** a user creates an activity and selects an existing route
- **THEN** the activity is linked to that route (route_id foreign key)
### Requirement: Activity feed
The Journal SHALL display a chronological feed of the authenticated user's activities.
#### Scenario: View own activity feed
- **WHEN** a logged-in user navigates to their feed
- **THEN** they see their activities in reverse chronological order with name, date, distance, and duration
### Requirement: Activity detail page
The Journal SHALL display an activity detail page with map, stats, and description.
#### Scenario: View activity detail
- **WHEN** a user navigates to an activity URL
- **THEN** they see the activity name, description, a map with the GPS trace, distance, duration, and elevation stats
### Requirement: Link activity to route
Users SHALL be able to link an existing activity to a route, or create a route from an activity trace.
#### Scenario: Link activity to existing route
- **WHEN** a user selects "Link to Route" on an activity and chooses a route
- **THEN** the activity's route_id is set to the selected route
#### Scenario: Create route from activity
- **WHEN** a user selects "Create Route from Activity"
- **THEN** a new route is created using the activity's GPX trace
### Requirement: Activity without route
Activities SHALL be allowed to exist without a linked route.
#### Scenario: Standalone activity
- **WHEN** a user imports a GPX activity without linking to a route
- **THEN** the activity is stored with route_id as null
### Requirement: Instance-wide public activity feed
The Journal SHALL expose a reverse-chronological feed of every activity on the instance with visibility `public`. This feed powers the instance home page (see `journal-landing`). `private` and `unlisted` activities SHALL NOT appear in this feed; `unlisted` stays reachable by direct URL only.
#### Scenario: Public activity appears in the instance feed
- **WHEN** an owner marks an activity as `public` and another visitor loads the home page
- **THEN** the visitor sees the activity in the instance feed, with the owner's display name, distance, and start date
#### Scenario: Private or unlisted activities stay out of the feed
- **WHEN** an activity's visibility is `private` or `unlisted`
- **THEN** it does not appear in the instance feed, regardless of who is viewing
