/* Standalone stylesheet for maxlearns.com games.
   The palette below is duplicated from src/styles/tokens.css by design — this file
   must work when a game is opened directly from the filesystem, so it cannot import
   anything outside public/. Keep both files in sync by hand.
   If this file fails to load, games must still be fully functional, just unstyled. */
