   Obrona miast / City Defense — game-specific styles (canvas frame, ammo HUD,
   mobile hint). Loaded together with games.css via $extraCss. The playfield is
   deliberately dark (night-sky arcade look), so the sky colours are literals
   like in games-najezdzcy.css; chrome uses site design tokens.
