Walkthrough

Adds the "World Inverted" map: source info.json, generator registration, compiled manifest with dimensions and nation placements, integration into GameMapType/category, playlist frequency, and English localization.

Changes

World Inverted Map Addition

Layer / File(s)	Summary
Map data asset and generator registry map-generator/assets/maps/worldinverted/info.json, map-generator/main.go	Source info.json defines the map name plus nations and additionalNations; main.go registers worldinverted so the generator will process it.
Compiled manifest with dimensions and nations resources/maps/worldinverted/manifest.json	Adds additionalNations, map sizing metadata for multiple resolutions (map, map16x, map4x), and the nations array with many coordinate placements.
Game type, playlist, and i18n integration src/core/game/Game.ts, src/server/MapPlaylist.ts, resources/lang/en.json	Adds GameMapType.WorldInverted, includes it in mapCategories.fantasy, adds GameMapName.WorldInverted to MapPlaylist.FREQUENCY with weight 8, and inserts map.worldInverted translation.

Poem

🗺️ A tilted world laid down in text,
Flags and points in careful rows,
From info to manifest, compiled next—
The game now knows where inverted winds blow. ✨

In `@map-generator/assets/maps/worldinverted/info.json`:
- Around line 316-317: Trim trailing spaces from all user-facing "name" values
in map JSON entries (e.g., change "Bellingshausen " -> "Bellingshausen", "SS
Florizel " -> "SS Florizel", "North " -> "North", "Bengal " -> "Bengal") and
correct obvious typos in names (e.g., "Artic" -> "Arctic", "East Pacfic Plains"
-> "East Pacific Plains"); update each matching "name" field in info.json
(including other occurrences with the same values) so displayed names are
normalized and consistent.
- Around line 745-755: The JSON array additionalNations contains a duplicate
entry for the nation with "name": "HMS Resolute"; remove the redundant object so
each nation name is unique (keep one {"name":"HMS Resolute","flag":"gb"} and
delete the other) to prevent map-authoring errors during nation creation; verify
the additionalNations array has no other duplicate "name" values before
committing.
