   AirPods Apple Website — scroll-controlled hero film
   Design system: near-black, one restrained teal-mint accent, huge
   tight-tracked display type. All animated properties are
   opacity / transform so the film stays on the compositor.
   The page background is the SAME #0b0b0d the film is composited
   onto, so the released pin hands over with no tonal step.
