/* =====================================================================
   RIA — LANDING EDITORIAL LAYER
   Inspired by oryzo.ai / awwwards-grade product stories. Adapted to
   RIA's brand (violet/cyan) — we steal the *grammar* (oversized
   display type, section numbering, generous whitespace, cinematic
   reveals, magnetic CTAs, 3D perspective) without the orange palette
   or WebGL/Three.js weight.

   Loaded only on the landing (index.html). Authed app pages keep the
   sober Linear/Vercel feel.
