Extract shared Tab, Escape and return-focus handling with explicit listener ownership. Preserve screen policy and validate unit, mutation, browser, tracking and CI checks.
Two independent triggers turned the global status chip red while every layer
was still populated (reproduced at JFK in Cockpit; timeline in the issue).
adsb.lol proxy: a non-OK upstream status was relayed verbatim even with a
12 s-old cache in hand, and the browser layer answers a 429 with a 45 s
cooldown in which every refresh reports "adsb.lol rate limited" without a
network call. The proxy now serves its cached body as STALE on a 429/5xx and
backs off from upstream for Retry-After (bounded), mirroring the OpenSky
proxy. A failure with nothing cached is still relayed.
Mapped installations: the "zoom in" guidance was stored in `error`, so the
manager reported a refresh failure and the chip a LOAD FAILED whenever the
view could not be bounded (Cockpit looks at the horizon). The status is now
set without an error string; the row reads the prompt from `statusMessage`,
and the chip ignores `error` for guidance statuses, matching the carve-out
layerFeedState already has.
Two independently toggleable open-data raster overlays — OpenSeaMap
sea marks (buoys, lighthouses, ports) and OpenSnowMap ski pistes —
drawn as Cesium.ImageryLayers directly on the Cesium globe surface.
Same "small array of descriptors" shape as MAP_STACKS in
mapStackController.js.
Visible on the osm/bing-aerial/bing-labels map stacks and invisible
(not broken — the layer's stats say so in plain text) on the default
photoreal stack, since Google Photorealistic 3D Tiles render with the
globe hidden.
OpenRailwayMap and OpenInfraMap, also requested in #10, are
deliberately NOT included in this pass: OpenRailwayMap's public tile
server enforces a Referer allowlist scoped to its own site (confirmed
by direct request — every other Referer, including none, 403s), and
OpenInfraMap serves MapLibre GL vector tiles, not raster XYZ — that
would need a genuine vector-tile rendering pipeline, not a
Cesium.ImageryLayer drop-in. Worth its own dedicated pass.

Use 64-point browser and upstream terrain batches to reduce cold-cache timeouts. Preserve successful chunk results, distinguish absent readings from malformed responses, and reject fabricated zero heights.
Original terrain resilience contribution by ItzDESTAQ, with browser batching, validation and regression follow-up by Sameh Khamis.
Validated with unit/build/format/boundary checks, 108 tracking checks, 5 terrain-outage checks, controlled slow-upstream comparison and live browser checks.
