   Paletki — game-specific styles (retro dark court, difficulty picker).
   Loaded together with games.css via $extraCss. Uses site design tokens;
   the dark court frame colours are deliberate literals matching the canvas
   painting in game-paletki.js (retro arcade look, like the classic palettes
   in games-2048.css / games-saper.css).
