/* Revealz — Memory Match game styles.
   Scoped entirely under .rvz-game-memory-match so it can be dropped into any
   theme's post-reveal DOM without colliding with the host page's own classes.
   Colors/fonts are read from CSS custom properties set inline by game.js from
   the active skin config — never hardcoded here except neutral chrome. */
