/* The product film: five moments on a dark stage that spans the viewport. The caption lives in the
   section head above the stage, the interface fills the stage, and the camera dollies and pans.
   The world has a fixed logical size (1440 × 800) scaled to fit. Only transforms and opacity move;
   no backdrop-filter inside the world. Light tokens are restored on every moment so the interface
   stays the light Enthy surface on the dark room. */
