# Changelog
## v0.4.1 — 2026-09-17 08:50
- Map-asset pack (~100 MB, 780 files) removed from git and from the Docker image: `git rm -r --cached public/{styles,fonts,sprites}` (files kept on disk), `.gitignore` now excludes exactly the generated paths (`public/styles/`, `public/fonts/`, `public/sprites/`, `public/map-assets-manifest.json`) — not all of `public/`; `.dockerignore` gets the same four entries; the v0.4.0 runtime-stage `COPY --from=build /app/public ./public` line is gone from the Dockerfile
- The pack now reaches the container via a docker-compose volume mount: `./public:/app/public` on the `flight` service — host dir present with assets → served locally; absent/empty → 404s → runtime fallback (below). Establishes the pattern for the future multi-GB tile file (v0.5.0) that must never go into git
- `scripts/download-map-assets.mjs` now writes `public/map-assets-manifest.json` as its LAST step (`{name, generatedAt ISO, styles: [ids]}`) so the manifest's presence proves the whole pack is in place; new npm script `"assets:download": "node scripts/download-map-assets.mjs"`
- Runtime fallback for fresh clones without the pack: `lib/mapStyles.ts` gains pure `styleUrlFor(id, localAssetsAvailable)` → `/styles/{id}.json` or `https://tiles.openfreemap.org/styles/{id}`, plus async `localAssetsAvailable()` — fetches `/map-assets-manifest.json` once (module-level cached promise; any non-200/network error → false); the single manifest probe is designed so a future self-hosted tile pack plugs into the same availability mechanism without rework
- `components/Map.tsx`: map creation in the mount effect is deferred until the probe resolves (one cheap local request before `new Map`), and the persisted-style restore was folded into that same post-mount flow — localStorage is still read only after mount (SSR-safe), applied at creation time so there's no fiord→saved flash; style switcher changes reuse the cached probe via `styleUrlFor`; all v0.4.0 behavior intact (fiord default, persistence key, idempotent `ensureAirportsLayer` on every `styledata`, single `/api/airports` fetch, `window.__flightMap`)
- Tests: unit — new `styleUrlFor` cases (local path / exact remote OFM URL) and `localAssetsAvailable` cases (false on non-200, true + cached with exactly one fetch across awaits via module reset, false on network error); e2e — new test "falls back to remote OFM styles when the local asset pack is absent" routes `/map-assets-manifest.json` → 404, lets `*.openfreemap.org/styles/**` through while aborting all other OFM traffic, and asserts the map initializes from the REMOTE style (glyphs still point at openfreemap.org), the airport count renders, and a UKBB marker click opens its popup — proving fresh-clone-without-assets usability end-to-end
- Verified: unit suite 21/21; `tsc --noEmit` clean; e2e suite green against the rebuilt compose instance with assets served from the bind mount (curl: `/styles/fiord.json`, a font `.pbf`, `/sprites/ofm.json` all 200); note the asset blobs remain in git history — no history rewrite was performed
## v0.4.0 — 2026-09-17 08:22
- Self-hosted all OpenFreeMap map-styling assets (tiles stay remote): new `scripts/download-map-assets.mjs` fetches the 5 OFM styles with a browser UA, rewrites each via `rewriteStyle`, and extracts the font/sprite tarballs into `public/` — committed so the image is self-contained: `public/styles/{liberty,bright,positron,dark,fiord}.json` (0.15 MB), `public/fonts/Noto Sans {Regular,Italic,Bold}/*.pbf` (768 files, 99.76 MB — the font payload), `public/sprites/ofm{.json,.png,@2x.json,@2x.png}` (0.21 MB); total public/ = 100.13 MB
- New shared module `lib/mapStyles.ts`: `STYLES` registry (5 ids + labels), `DEFAULT_STYLE_ID = 'fiord'`, and pure `rewriteStyle()` — glyphs `https://tiles.openfreemap.org/fonts/{fontstack}/{range}.pbf` → `/fonts/{fontstack}/{range}.pbf`, sprite `https://tiles.openfreemap.org/sprites/ofm_f384/ofm` → `/sprites/ofm`; the vector tile url (`/planet`) and ne2_shaded raster tiles (`/natural_earth/ne2sr/...`) are left remote; every source lacking an attribution gets `"© OpenStreetMap contributors © OpenFreeMap"` (OFM styles ship none; ODbL requires visible OSM credit)
