   Timberman — fixed "forest daytime" theme.
   Same page frame as Flappy Bird (full-height app shell, frosted top bar,
   chunky arcade buttons, hard-shadow stage, card overlays, colored rules
   modal) but with this game's own palette, taken straight from its canvas:
   leaf green, log brown, lumberjack red, harvest gold, deep-brown ink.
   Deliberately ignores the center's light/dark mode; no glass.css loaded.
