   RE.STATICA — PRACTICE GAME (card-game board)
   Fixed viewport: top HUD (tabs · step · hearts · progress), the problem as
   the encounter up top, your hand of cards pinned along the bottom.
   Dark "game surface" regardless of app theme; accents borrow the app vars.
   All scoped under .rs-practice / .rs-practice-stage.
