/* ============================================================================
   LattIQ · T4 colour morph - morph.css  (return package v2)
   ----------------------------------------------------------------------------
   v2 per design review: NO feathered self-paint, no masks, no ::before
   overlays - the runs are monotonic and the fixed backdrop is the only
   background layer, so nothing can produce a seam or notch.

   2026-07-23: the engine now runs on mobile too (Akash: colour-morph on mobile
   at full quality). So the legibility rules (border kills, light-green text
   retune, decorative-pseudo kills) are keyed only on html[data-morph="full"]
   and apply at EVERY width - the engine sets that attribute wherever it runs.
   The 100vh flex "chapter" layout stays desktop-only (mobile keeps natural
   section heights so the page doesn't balloon).
