+- Add Sea Marks (OpenSeaMap) and Ski Pistes (OpenSnowMap) as two raster

+  Google 3D, and share links keep each one (Tom-Neverwinter, #114).

+- Add optional keyless Radio priority-country coverage with up to 40 stations
+  per configured country inside the existing 750-station cap; the UK alias uses
+  the canonical GB code. Country query

+- Keep Overpass-backed layers working behind a reverse proxy: `/api/overpass`
+  now uses the keyless same-site gate, admits forwarding headers and still
+  refuses cross-site requests. Direct loopback requests keep their own
+  admission window; proxied requests, including those a local reverse proxy
+  relays over loopback, are admitted as remote traffic keyed by their socket,
+  and IPv6 peers are keyed by /64, so neither LAN peers nor proxied users can
+  exhaust the owner's admission. The upstream budget stays shared, so an owner
+  cache miss can still be rate-limited (asturksever, #1308).
+- Give the tracking arrival check a wall-clock budget per observed frame and
+  retry only an inconclusive timeout: a timeout keeps every angle it
+  measured, including a late frame's, and a wrong one fails without retry, so slow software-rendered
+  frames no longer fail the check and a real violation is never retried into a
+  pass (asturksever, #1308).

+- The Global Context range ring pulses like a sonar: three dim rings with a

+- Voice can reuse what it outlines. `resolve_area` turns a named place into a

+  an area, the view or the spot under the pointer (manjunath22466, #846).
+- `osm_query` ("hospitals in Kathmandu") lists places of one kind into a

+  named "aircraft". Follow-ups keep the displayed scope and the loaded-data
+  caveat until a new scope replaces them (manjunath22466, #846).
