The wall now comes back exactly as it was left: overlays, basemap and viewport ride in the URL hash and are remembered per browser. ?kiosk=1 (or #kiosk) turns it into a wall display.

Saved views

Hash keys (all optional, unknown keys ignored, old inc/cam/tour links still work): layers=nodes,inc,paths,air,ais,dotcam,vs,traffic,radar, z/lat/lon, base=dark|light|streets, tourMs, kiosk, and f.<name>=<value>, which passes through untouched as WallLink.filter for #235.
Precedence: hash > this browser's last view (localStorage, every access in try/catch) > defaults (Nodes, Active Incidents, Incident Paths, as before).
The address bar is always a working link to the current view. The new Copy view link button copies it. Editing the hash by hand remounts the map with the new view.
The persisted viewport is the region view, so a reload doesn't come back zoomed into one incident.
Folds #137: closing an incident flies back to where the viewer was before drilling in.

Kiosk

Nav hidden on /, so the wall gets the full screen.
Fullscreen button. Fullscreen also turns on at the first touch or keypress, because browsers require a gesture; a browser launched with its own kiosk flag needs no click.
Screen Wake Lock, re-acquired on visibilitychange. Where the browser doesn't support it, this is skipped silently.
Reconnect banner: shown when offline or when useCalls returns an error. In kiosk mode the page reloads with backoff (30 s up to 10 min); everyone gets a Retry button. The hooks are untouched.
18-20 px type through data-kiosk on the LiveView root plus Tailwind arbitrary variants (no globals.css). Checked against the Tailwind 3.4.19 compiler output.

Fix found on the way: react-leaflet adds a checked overlay to the map before registering it with LayersControl, so no overlayadd fires for it. useOverlayShown now starts from the initial layer set. Otherwise a saved DOT Cameras / Traffic / Viewsheds layer would have shown up ticked but empty.

Not touched: WallPanels.tsx, c2api.ts, types.ts, the backend, discord files. The RadarLayer remount workaround is intact.

Verification

tsc --noEmit exits 0 (fresh scratch copy).
c2-core pytest: 854 passed, 4 warnings.
Hash parse/serialise round-trip checked with an ad-hoc node script (not committed; no JS test runner exists).
Not browser-tested. The acceptance steps (tick Radar + Cameras then reload, open the copied URL in a second browser, kiosk after a browser restart, private window) still need a manual pass.

Closes #234
Closes #137

Live wall: saved views in the URL hash, per-viewer memory, kiosk mode (#234 ) afd2bc463d

- liveWall.ts: WallLink carries layers (short stable keys), z/lat/lon,
  base, tourMs, kiosk and an f.<name> filter pass-through for #235;
  parse/serialise stay pure and round-trip; old inc/cam/tour links parse.
- MapView: overlays/basemap/viewport come from initialLayers/initialBase/
  initialView (defaults unchanged); onViewStateChange reports layer, base
  and region-view changes (debounced). Initially-checked overlays now start
  "shown" (react-leaflet adds a checked overlay before the control can fire
  overlayadd). Closing an incident flies back to the pre-drill view (#137).
- wallPrefs.ts: per-browser last layers/base/view in localStorage, every
  access wrapped; precedence hash > remembered > defaults.
- LiveView: one effect mirrors wall + map state into the hash; hash edits
  remount the map with the new view; Copy view link; configurable tour.
- Kiosk (?kiosk=1 or #kiosk): no nav, fullscreen button (auto on first
  touch), Screen Wake Lock re-acquired on visibility, reconnect banner
  (offline / useCalls error) with backoff reload, 18-20 px type via a
  data-kiosk attribute and Tailwind arbitrary variants.

Live wall: report the starting view once so a copied link carries the viewport (#234 ) b6055019fc

Without it the URL had no z/lat/lon until the first pan, so a link copied
from an untouched wall opened at the other browser's remembered view.
