/*
  Pibb Game — stylesheet
  ======================
  Design tokens live in :root. Layout is a horizontal split:
    [ game-area (flex 1) | chat-sidebar (fixed width) ]

  Legacy lobby styles (.tabs, .card, etc.) remain for potential reuse;
  the live app skips the lobby and uses body.in-room immediately.
