/* =============================================================
   Corner Plot Media — Design System
   -------------------------------------------------------------
   Structure adapted from the Mill3 / b2b2go reference:
     · warm paper neutrals + deep navy + one hot accent
     · expo-out reveals, 90px travel, 1.05s transform / .45s opacity
     · opacity .001 -> .999 (keeps the layer GPU-composited
       throughout, avoiding promotion/demotion jank)

   Deviations, deliberately:
     · no smooth-scroll library (Locomotive hijacks native scroll
       and wrecks INP). ScrollTrigger/IntersectionObserver only.
     · reveal states are gated behind .js so the page is fully
       readable with JS disabled or broken.
