## ADDED Requirements
### Requirement: Map rendering with OSM tiles
The Planner and Journal SHALL render interactive maps using Leaflet with OpenStreetMap tiles as the default base layer.
#### Scenario: Default map view
- **WHEN** a user opens the Planner or a route view in the Journal
- **THEN** an interactive map is displayed with OpenStreetMap tiles centered on the route or a default location (Germany)
### Requirement: Base layer switching
The map SHALL support switching between multiple base tile layers.
#### Scenario: Switch to OpenTopoMap
- **WHEN** a user selects "OpenTopoMap" from the layer switcher
- **THEN** the map tiles change to topographic tiles from OpenTopoMap
#### Scenario: Available base layers
- **WHEN** a user opens the layer switcher
- **THEN** the options include OpenStreetMap, OpenTopoMap, and CyclOSM
### Requirement: Waypoint editing on map
The Planner map SHALL allow users to add, move, and delete waypoints by interacting with the map.
#### Scenario: Add waypoint by clicking
- **WHEN** a user clicks on the map
- **THEN** a new waypoint is added at the clicked location and synced via Yjs
#### Scenario: Move waypoint by dragging
- **WHEN** a user drags an existing waypoint marker
- **THEN** the waypoint coordinates update and sync via Yjs
#### Scenario: Delete waypoint
- **WHEN** a user right-clicks a waypoint and selects "Delete"
- **THEN** the waypoint is removed and the change syncs via Yjs
### Requirement: Route visualization
The map SHALL display the computed route as an interactive, optionally color-coded polyline on the map.
#### Scenario: Display route
- **WHEN** BRouter returns a route GeoJSON
- **THEN** the route is rendered as a polyline on the map, colored according to the active color mode
#### Scenario: Route updates on waypoint change
- **WHEN** a waypoint is added, moved, or deleted
- **THEN** the route polyline updates after BRouter recomputes the route
#### Scenario: Ghost marker on hover
- **WHEN** the cursor is within 15 pixels of the route polyline
- **THEN** a transient ghost marker appears at the nearest route point, which can be clicked or dragged to insert a waypoint (see route-splitting and route-drag-reshape specs)
### Requirement: Elevation profile display
The Planner SHALL display an elevation profile chart for the current route.
#### Scenario: Show elevation profile
- **WHEN** a route is computed
- **THEN** an elevation profile chart is displayed below the map showing distance vs elevation with total ascent/descent statistics
### 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
### Requirement: Map cursor rendering
Other participants' cursors on the map SHALL be clearly visible with proper styling.
#### Scenario: Cursor appearance
- **WHEN** another participant moves their mouse on the map
- **THEN** a colored pointer icon with their name tag appears at the cursor position
#### Scenario: Cursor does not obscure map controls
- **WHEN** cursors are rendered
- **THEN** they appear below map controls (zoom, layer switcher) in z-index
### Requirement: Map components used in journal app
The `@trails-cool/map` package's `MapView` and `RouteLayer` components SHALL be used in the journal app for route previews, in addition to the planner.
#### Scenario: Journal uses shared map components
- **WHEN** the journal renders a route map preview or detail map
- **THEN** it uses `MapView` and `RouteLayer` from `@trails-cool/map`
- **AND** no map code is duplicated between planner and journal
### Requirement: Map polygon drawing
The Planner map SHALL support drawing and displaying no-go area polygons.
#### Scenario: Polygon tool
- **WHEN** a user activates the no-go area tool
- **THEN** they can draw a polygon by clicking points on the map
#### Scenario: Polygon display
- **WHEN** no-go areas exist in the session
- **THEN** they are rendered as semi-transparent red polygons on the map
