   Palette: harvest gold, burnt orange, avocado green, chocolate brown, cream.
    Every game-scoped style is prefixed with the game's short code:
      .dc-  Dot Connect      .vs-  Visual Sudoku    .wc-  Word Connect
      .hx-  Hexablock        .bd-  Block Drop       .mm-  Memory Match
    Shared building blocks (buttons, chips, overlays, toasts) are unprefixed.
    Shell features that aren't games use their own prefixes: .fb- feedback.
