GPS permission:
- Remove silent mount-time getCurrentPosition calls that cause iOS Safari
to cache a "denied" state without ever prompting the user
- LocateButton always retries getCurrentPosition on tap (user gesture)
- Only show "denied" toast on PERMISSION_DENIED (code 1), not timeout
- MapView watchPosition now starts only after confirmed grant, not unconditionally
Traffic toggle:
- Fix isStyleLoaded() race in LayerControl — if style not loaded when
toggle fires, defer to map.once("style.load") instead of silently bailing
- Change outside-click handler from mousedown to pointerdown for mobile
Mobile UX (from prior session):
- Add LocateButton component (crosshair GPS locate/re-center)
- Reposition layer control + locate button to top-right on mobile
(below MapLibre nav controls, above bottom sheet)
- ModeSelector: add min-w-0 to prevent flex overflow at 390px
- StopItem: remove button visible on touch (60% opacity vs hover-only)
- Panel: overflow-x-hidden + safe-area-inset-bottom on mobile sheet
- Body overflow-x guard on mobile viewports

- New LayerControl component with popover toggles for hillshade/traffic
- MapView: add/remove hillshade raster-dem and traffic raster layers
- Overlay layers persist in localStorage, survive theme swaps
- Hillshade defaults ON, traffic defaults OFF when available
