/* ════════════════════════════════════════════════════════════════════
   OUR PROCESS — Cinematic Hero
   Isolated component (see process-hero.js). Replaces the previous
   .hero furnace banner on process.html only. Full-bleed photographic
   composition of the glowing steel billet on the rolling line
   (Hero/our-process.*) with a single left-to-right scrim carrying the
   headline — one full-inset photo + one scrim, matching the site's
   established hero convention (.q-hero in quality-hero.css, .oj-hero
   in journey-hero.css, .gc-hero in group-hero.css), not a boxed image
   stitched against a separately drawn background. A five-stage process
   timeline is overlaid across the lower band of the same photo.

   Motion contract: only transform / opacity are animated on anything
   that runs continuously. Width, height, margin, left and top are
   never transitioned.
