   Taxi — fixed "cab yellow" theme.
   Same page frame as Ambulance / Flappy / Timberman (full-height app shell,
   frosted top bar, chunky arcade buttons, hard-shadow stage, card overlays,
   colored rules modal) but with this game's own palette taken straight from
   its 3D scene: checker-cab yellow, ink black, asphalt grey, money green,
   fuel amber, sky blue. The stage is a 16:9 landscape board because this is
   a driving game. Deliberately ignores the center's light/dark mode; no
   glass.css loaded. The c-* chrome lives HERE on purpose — it is not
   inherited from the shared stylesheets.
