/* Bullet Time web app. Multicam lineage (Inter, white pill CTA, lime "frozen" signal), pushed further with Refero references:
   Krea: pure black canvas, monochrome surfaces, a dark cinematic scene behind the hero, neutral active states.
   FLORA: flat cards (no heavy shadows), accent reserved for status and active edges only.
   Runway / Synthesia tool screens: the output stage doubles as the live render canvas while a job runs. */
