Update route-coloring spec with all 10 modes, create follow-up changes
Spec updates:
- route-coloring: Added speed limit, smoothness, track type, cycleway,
and bike route modes. Added OSM wiki links, BRouter profile patching,
dropdown order, bike route human-readable legends.
New follow-up changes (proposals only):
- elevation-map-interaction: Bidirectional chart ↔ map interaction
(route hover → chart, chart click → pan, chart drag → zoom)
- e2e-test-reorganization: Mock BRouter by default, split tests by
feature, shared helpers
- journal-poi-details: Surface POI metadata in Journal route detail
(phone, address, website, opening hours from snapped waypoints)
