   game-shell.css — shared chrome for the 4-screen game suite.
   Every game page (solitaire, mancala, chess, checkers, bubble) loads this
   plus game-shell.js and a window.GAME_CONFIG. The four screens — Game,
   Analog, Instructions, Facilitator — are persistent panels switched by a
   pill toggle; an in-progress game keeps its state because hidden panels are
   only display:none, never torn down.
   Aesthetic matches decks.html (green terminal on near-black).
