Remove the home-city name from docs/comments/UI strings and the external
mirror IP (WAN) from code, docs and the Android cleartext allowlist, replacing
the IP with mirror.invalid (set the real host locally, uncommitted). LAN mirror
and routing keep working; the WAN fallback needs the real host set. Generic
big-city map presets are kept (not identifying).
Static brouter-web on the Keenetic mirror pointed at the PC RouteServer.
config.js (host/layers/centre), baldav-custom.{css,js} (day/night toggle that
inverts only the tile layer + dark sidebar, one-time default POI overlays),
and a README with the deploy steps. Kept in-repo so the mirror is reproducible.
