- Replace the bogus DroidSansJapanese.ttf (an HTML page) with M PLUS Rounded 1c,
loaded with LoadFontEx and explicit kana codepoints
- Theme struct per language with flag-based card backs (Hinomaru, Taegukgi, Trairong)
- Card art rendered to textures so the flip squashes the whole card
- Synthesized flip/match/mismatch/win/click sounds (new audio package)
- Shared ui package for text and buttons; Screen enum replaces i32 ids
- Kana <-> romaji pairs drawn from all 46 basic hiragana
