/* /oer V2 — Senken-brand polish pass.
   Parallels /2035's design language with its own visual rhythm.
   Tokens live in tokens.css; this file adds page-specific structure.

   Section rhythm (top → bottom):
     §1 Hero        — Enstatite warm + ripple watermark
     §2 Claim       — Obsidian dark (the page's anchor moment)
     §3 Positions   — White (cool, comparison)
     §4 Portfolio   — Enstatite cream (warm product moment) + obsidian audit subsection
     §5 How it works— White
     §6 Trust band  — Enstatite (continuous with hero rhythm)
     §7 Bridge      — Jade dark (with jasper accent)
     §8 FAQ         — Enstatite cream
     §9 Final CTA   — Obsidian dark

   Memory rule observed: jasper text appears only on Obsidian or Jade. Never on cream/quartz/white. */
