/* ============================================================
   VAULT HERO — the homepage hero scene.

   Tier 0: an inline SVG poster, always painted, never blank.
   Tier 1: CSS-3D cards driven by one rAF loop (vault-scene.js).
   The <h1> stays the LCP element — the scene sits behind it and
   is decorative (aria-hidden), so it is never LCP-eligible.

   Typography is inherited from styles.css (Inter). Nothing here
   sets a font. Colours come from the tokens below so the scene
   re-lights for dark mode without touching the scene code.
