   Shared design system. Cream editorial brand base +
   cinematic dark hero band, living aurora depth, and the
   signature Audit-Thread / Merkle-seal hairline.
   All motion = transform/opacity/filter only, 60fps,
   fully collapsed under prefers-reduced-motion.
   Per-product accent: ForgeShield=teal, LrForge=orange,
   Storygild=violet. Orange #FF6B35 stays the brand CTA.
