/* ==========================================================================
   Trzecia w nocy — styles.css
   Immersive scroll film. Display: Big Shoulders variable 100..900 (local,
   fonts/BigShoulders-Variable.woff2). Body: Manrope 400/500 (fonts/fonts.css).
   Warm ivory on petrol-black, carmine = danger (night), amber = dawn.
   Runtime hooks (see CONTRACT.md): html.no-js/.js, html.motion-on/.motion-off,
   --p on .scrub-scene and [data-track], --mx/--my on .scrub-media,
   --story and --warmth on html, body.mood-*, .video-ready/.video-failed,
   .is-past/.is-active on .step. The loop orbit reads --p on .loop plus
   .is-active on .cycle-word (one carmine word per quarter turn).
