/* ============================================================================
   GAME PAGE — the layout every game page shares, modelled on the Shotoshot page.
   Structure only: each game sets its own tokens (colours, fonts) in its own
   css/style.css, loaded after this file, and adds its signature touches there.
     --bg --panel --line --text --muted   ground, cards, rules, type
     --accent      marks: links, buttons, the underline, the asterisks
     --soft        the quieter second line of a heading
     --sans --mono
   Clips are framed and kept near their native 800 px: never a background.
