Base map / tiles:
- Switch the base map to the mapchart city-label world map; re-derive its
Web-Mercator georeferencing (MAP_LON0/1, MAP_IMG_MY0/1) by least-squares
against the pixel-identical graticule export.
- Add a 1.5x LANCZOS supersample LOD and bump tile quality 90->94 so city
labels stay crisp when zoomed in (tools/png_to_tiles.py).
- Fill the map view background with the ocean colour instead of black.
Navigation / clustering:
- Snap the cluster grid to power-of-two zoom octaves so the bubbles stop
jittering during a continuous zoom.
- Replace the loose zoom clamps with named MAP_SCALE_MIN/MAX (whole map fills
the screen .. country/region level).
- Add a toggleable computed lat/lon graticule overlay (TRIANGLE).
Cluster gallery:
- Selecting a bubble now opens all its photos on the same justified grid as
the timeline/search (a g_gallery_active filter). Members not already paged
in are appended as hidden g_asset entries (kept out of the main timeline);
a background metadata worker resolves each one's date/aspect so the grid
reflows into month sections + true aspect ratios.

New src/map.c (unity-build part) adds a map screen reached from the search
bar's map button:
- Fetches geotag markers (GET /api/map/markers), projects with Web Mercator.
- Clusters markers into count "bubbles" in map space (anchored to the world,
so panning translates them instead of reshuffling); pan (d-pad/touch),
zoom (L/R/pinch). X or tap zooms into a cluster, or opens a lone/co-located
photo — fetching that asset on demand if it isn't paged into the grid —
and returns to the map on back.
- Base map: a Web-Mercator LOD tile pyramid generated offline from a MapChart
PNG (tools/png_to_tiles.py -> assets/maptiles.pak); the level matching the
on-screen scale is drawn from 256px JPEG tiles decoded into pooled textures
(the crash-safe path), with a coarse overview underneath so there are no
gaps while tiles stream in. Georeferencing (full longitude, lat band) was
fit from isolated-island centroids so markers land on land.
main.c uses a larger vita2d vertex pool; app.c wires the mode in.
