## Description:
Relates to #3725
Adds a new **Impassable** terrain type that enables non-rectangular maps
and creates impassable barriers on the map. Painted with pure black
(`#000`) in the map editor's `image.png`.
**Encoding:** Impassable terrain is encoded in the binary format as
`isLand=1, magnitude=31` (previously unused). The Go map generator
detects `#000` pixels and produces this encoding. The map generator's
minimap downscaling gives impassable highest priority (Impassable >
Water > Land). Thumbnails render impassable as transparent so the map
picker background shows through.
**Rendering:** Impassable tiles render as the map background colour
(`rgb(60, 60, 60)`, matching `gl.clearColor` in `Renderer.ts`), making
them visually indistinguishable from the area outside the map quad. This
enables maps to appear non-rectangular.
**Gameplay restrictions:** Impassable terrain cannot be:
- Owned (`conquer()` throws)
- Attacked (`AttackExecution` skips impassable tiles in both `tick()`
and `addNeighbors()`)
- Nuked (targeting rejected in `nukeSpawn()`, blast radius filtered in
`tilesToDestroy()`)
- Spawned on (nations, human players, and structures all reject
impassable tiles)
- Converted to water (guarded in `WaterManager` and `setWater()`)
**Nuke trajectories:** Nuke trajectories cannot cross impassable
terrain, matching the existing map-border enforcement. This is checked
at launch time in `NukeExecution.tick()`. The client-side trajectory
preview turns red with a red X where the arc crosses impassable terrain
(reusing the existing SAM-intercept visual pipeline in
`NukeTrajectory.ts`). The nuke ghost preview is completely hidden when
hovering over impassable terrain (same as hovering outside the map).

Tested with water nukes, made sure there is no water depth gradient near
the impassable terrain, just like at the world border:

**Add approved & assigned issue number here:**
N/A — maintainer refactor.
## Description:
Makes each map's `info.json` the single source of truth for map metadata
— adding a map is now a folder with `image.png` + `info.json`, a
`gen-maps` run, and an en.json display name.
**info.json / manifest.json carry full map metadata.** Every
`map-generator/assets/maps/<map>/info.json` declares `id` (the
`GameMapType` enum key), `name` (the enum value — wire format, unchanged
for all 94 maps), `translation_key`, `categories`, and
`multiplayer_frequency` (the public-playlist weight that used to be the
`FREQUENCY` record in MapPlaylist.ts). The generator validates
everything and mirrors it into `resources/maps/<map>/manifest.json`. 23
stale info.json `name` values were normalized to the canonical enum
value; enum values are byte-identical, so replays and stored game
configs are unaffected.
**The generator emits the TypeScript and discovers maps itself.** New
`map-generator/codegen.go` generates `src/core/game/Maps.gen.ts`
(`GameMapType`, `GameMapName`, `mapCategories`, `mapTranslationKeys`,
`multiplayerFrequency` — now a full `Record<GameMapName, number>`,
killing the old `Partial`) on every run; `Game.ts` re-exports it. The
hardcoded map registry in `main.go` is gone — maps are auto-discovered
from the `assets/maps` / `assets/test_maps` directories. MapConsistency
tests fail with a "run `npm run gen-maps`" message if info.json,
manifest.json, and Maps.gen.ts drift. The tracked
`map-generator/map-generator` binary is rebuilt to match.
**New categories: continents + world/cosmic/tournament/other,
multi-category support.** `continental`/`regional`/`fantasy`/`arcade`
are replaced by `featured`, `world`, `europe`, `asia`, `north_america`,
`africa`, `south_america`, `oceania`, `antarctica`, `cosmic`,
`tournament`, and `other`. Maps can list multiple categories, so
straddlers (Black Sea, Bosphorus, Caucasus, Between Two Seas, Bering
Sea/Strait, Mena, Strait of Gibraltar, Hawaii, Arctic) appear under both
regions. Featured is itself a category (same 7 maps as before).
MapPlaylist keeps its arcade exclusion via an explicit set.
**Map picker UI.** Two tabs: **Featured** (default — featured maps plus
a Favorites section when maps are starred) and **All** (one prominent
collapsible bar per category with a map count, collapsed by default).
The selected map is prepended to the featured grid when it lives
elsewhere. `getMapName()` resolves through the generated
`mapTranslationKeys`, which also fixes tourney maps never resolving a
valid translation key.

## Description:
Add Map - Los Angeles (With Roads)
Whats NY without LA? What is LA without its roads? Here is a larger map
where I have turned LAs road network into rivers. Nations named to areas
of the city or surrounding area. Map geo data is from OpenTopography. I
stenciled the highways from screenshots of online maps and some artistic
choice.
