N/A — maintainer follow-up to #4227.
## Description:
Follow-up to #4227, finishing the "info.json is the single source of
truth" refactor.
**Maps.gen.ts now generates one `MapInfo` interface and a `maps` list**
instead of parallel lookup records. `mapCategories`,
`mapTranslationKeys`, and `multiplayerFrequency` are gone — consumers
read the list directly (`map.categories`, `map.translationKey`,
`map.multiplayerFrequency`). MapPicker got simpler in the process: it
renders from `MapInfo` objects, so the reverse
`Object.entries(GameMapType)` lookup to recover the enum key is gone.
The featured-rank sort moved out of the Go codegen into the picker,
where the presentation concern belongs.
**`SPECIAL_TEAM_MAPS` moves into info.json** as an optional
`special_team_count` field (set on the same 17 maps with the same
values). MapPlaylist derives its map from the generated list;
`SPECIAL_TEAM_FORCE_CHANCE` and the frequency multiplier behavior are
unchanged.
**The en.json `map` section is now generated.** A new optional
`display_name` field in info.json (defaulting to `name`) is written to
`resources/lang/en.json` by the generator, preserving the section's
non-map UI keys (`map`, `featured`, `all`, `favorites`, `random`). The 8
maps whose English display name intentionally differs from the frozen
enum value (e.g. `MENA`, `Milky Way`, `Europe (Classic)`, `Baikal (Nuke
Wars)`) declare it via `display_name`, so no display text changes. The
section is emitted alphabetically; since #4232 already sorted en.json
and every value matches, regeneration is byte-identical and this PR has
no en.json diff. Other languages remain Crowdin-managed.
The generator also now validates `translation_key` is exactly
`map.<folder>` and `special_team_count >= 2`. MapConsistency tests
compare info.json directly against the generated list and the en.json
section, and fail with a "run `npm run gen-maps`" message on drift. No
behavior changes: enum values, playlist frequencies, special-team
counts, featured order, and display names are all byte-identical.
## Please complete the following:
- [x] I have added screenshots for all UI updates (no UI changes —
internal refactor, rendering output identical)
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory

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.

Resolves#4165
## Description:
This PR update the test checking validity of Nation Names to include the
new character constraint explained below.
It also fixes the 10 Nations that invalid characters (that did not
render correctly on the map).
**The new character constraint**
According to testing, the game map renders correctly all safe
Extended-ASCII characters (non colored in www.ascii-code.com =
[0x20–0x7E] or [0xA0-0xFF]). Other characters, when present in Nation
Names, are rendered correctly in the rest of the game but not on the
map, where they are trimmed to the last byte, which is then interpreted
as Extended-ASCII and rendered if possible.
**How to quickly check my assertion**
1. Change the file resources/maps/world/manifest.json, renaming one of
the countries to "a.á.आ!š!慢!".
2. Start a game on the world map without any bots
3. Verify that the nation name is well displayed in its overlay but is
shown as "a.á.!a!b!" on the map.
(characters before a point are preserved, but characters before an
exclamation mark are missing/changed).
4. run `npm run test` and notice that the NationName test fails and
lists the three non-valid characters.
Explanation: The string is represented in UNICODE-16 as
\u0061\u002e\u00e1\u002e\u0906\u0021\u0161\u0021\u6162\u0021.
Which, when we keep only the right-most byte of each character gives:
61 2e e1 2e 06 21 61 21 62 21
And, converted in Extended-ASCII gives:
a.á.�!a!b!
(which matches the showed name if we discard the control character).
**The 10 Nations which needed a fix**
Utqiaġvik from the Bearing Strait.
Ar Rayyān from the Strait of Hormuz.
6 Nations in the Bosphorus Straits.
2 Easter-egg Nations from Luna.
The 8 real-world Nations were adapted by simply removing the diacritics
(after confirmation from a speaker of arabic and turkish, but sadly none
for the Utqiaġvik Nation).
The Secret Base from Luna was renamed "T0Þ $e¢®ët Mi|¡tªr¥ ß@§£", all
within Extended-ASCII, keeping the same spirit as the original name.
However, the Monolith Nation (previously named ▊, without any flag) has
changed quite a lot and needs some explanation.
**Easter-egg Nation Monolith**
The new name is "ΜΟΝΟʟΙȚΗ", which is entirely outside of the valid
character zone but in a way that entirely disappears on the map (as the
आ character in the example above). This means that on the map, the
Nation has no name and only its Monolith-flag.
However, in all other places (leaderboard, overlay, alliances, warnings,
etc.) the name is displayed correctly.
The included test excludes this precise name from its violation list.

## Description:
Corrected inbalance in Luna map between top and bottom. Now both sides
have about equal land tiles.
Testing and editing was done to help boat-pathing at least look normal
along bottom half.
Additional notch cut in orbit lines to take edge off boat-pathing. Now
obstacle is almost a straight line.
Filled in center orbits to help players push easier. It was reported to
be tedious previously.
'Top Secret Military Base' nation was renamed with only vowels blacked
out for easier reading of joke name.
'Monolith' nation was renamed with a special character that displays
like the actual Monolith.

## Description:
Small-island removal previously ran only on the full-size terrain. The
compact (4x downscaled) map inherited that filtering before being
downscaled, which meant islands that survived at full size could end up
as tiny specks in the compact map.
This PR runs `removeSmallIslands` on the 4x terrain as well, with half
the threshold (15 vs 30 tiles), so very small islands are pruned in
compact maps while the full-size map is unchanged.

## Description:
Adds spawn areas to the Luna map for 2 teams, given the map is very
symmetrical and would fit nicely with other team-centered maps like
baikal and 4islands. Thanks to deshack for suggesting this.
