- Enforced 'Style 32 - Dark Chibi Vector' for all ground assets.
- Fixed critical Prologue-to-Game crash (function renaming).
- Implemented Tiled JSON/TMX auto-conversion.
- Updated Asset Manager to visualize 1800+ assets.
- Cleaned up project structure (new assets/grounds folder).
- Auto-Ground logic added to GameScene.js.
