Major refactor consolidating two-panel layout (Routes/Contacts + floating
PlaceDetail) into one 400px left column with state-driven content.
Architecture:
- New PlaceCard component for preview and stop cards (collapsible)
- Panel states: IDLE, PREVIEW, ROUTING, PREVIEW_ROUTING, ROUTE_CALCULATED
- usePanelState selector in store.js derives state from selectedPlace/stops/route
- StopList now renders stops as PlaceCard with variant=stop
- PlaceDetail.jsx removed from App.jsx (content moved to PlaceCard)
UX refinements:
- Panel width 400px (was 360px) to fit buttons on one line
- Map zoom padding updated to 420px for wider panel
- Body text bumped to text-sm (14px) for readability
- Get Directions button hidden when 2+ stops (route auto-calculates)
- PlaceCard title prefers feature name (raw.name) over formatted address
- Preview card shows above route during PREVIEW_ROUTING state
- Directions flow no longer shows toast when GPS denied
