/* ════════════════════════════════════════════════════════════════════
   ALUMINIUM FOIL HERO — cinematic industrial split (Aluminium Foil page
   only). Isolated component: scoped tokens on .ah-hero, own markup, own
   entrance system. Mirrors ferro-hero.css / product-hero.css's proven
   technique — one real photo (Hero/Aluminium_Foils.png: aluminium foil
   rolls, an unrolled reflective sheet, rolling-mill machinery and a
   digital world map with orange trade-route arcs) bleeds edge-to-edge
   on desktop behind a single scrim, weighted right so the left text
   column reads clean; on mobile it stays a full-bleed background behind
   the stacked text, matching the homepage / ferro-alloys / steel hero.
