   Space Shooter — styles
   ---------------------------------------------------------------------------
   Deliberately the same design language as the Snake game
   (games/snake-game/css/style.css): ink panels, parchment type, brass and
   jade accents, Fraunces / Inter / IBM Plex Mono, 12px radii, flat buttons.
   Every selector is scoped under #space-shooter (or .shooter-page for this
   standalone page), so nothing leaks into — or in from — a host page.
