Problem

MapView.tsx:351 — 'Overlays start unchecked'; only Nodes, Active Incidents and Incident Paths are checked (MapView.tsx:1228-1242). Radar, cameras, viewsheds, traffic, aircraft, vessels reset to off on every load. The wall hash (liveWall.ts:158-163) carries only inc/cam/tour — no layers, viewport, basemap or filters. No fullscreen, Screen Wake Lock, reconnect detection or large-type mode exist in drb-frontend. A wall PC that reboots at 03:00 comes back bare.

Who asked

All 8 personas. Highest-demand single item.

Proposal

Extend parseWallHash/wallHash with layers, z/lat/lon (or bbox), base, tourMs, and the filter state from the filter-bar issue.
Remember each viewer's last layers/viewport in localStorage (wrapped in try/catch; render correctly without it).
?kiosk=1: hide nav, fullscreen button, Screen Wake Lock, reconnect watchdog (snapshot listener error/offline → visible banner + retry), 10-foot type scale (18-24 px rail text).
Org-shared named profiles: later, and server-mediated via c2-core, because Firestore rules are not deployed (#13).

Data source and terms

None external.

Effort

S

Acceptance criteria

Ticking Radar + Cameras, reloading, and opening the copied URL in another browser both restore the same layers and viewport.
Kiosk mode survives a browser restart with no clicks and keeps the screen awake.
Works with storage blocked (private window).

Notes

Fold #137 (zoom back on close) into the same view-state work if convenient.

## Problem `MapView.tsx:351` — 'Overlays start unchecked'; only Nodes, Active Incidents and Incident Paths are `checked` (`MapView.tsx:1228-1242`).
