/* About page v2 — 2026-08-25, implementing the owner's Claude Design draft
   `PDM About Page.dc.html` inside the site layout.

   The draft is dark-only with fixed hex; this page also renders light, so every
   colour maps to a site token. Mono is the local stack — no Google Fonts.

   Section numbers (01, 02, 03) come from a CSS counter on the kickers, the same
   device the features page uses, so the markup stays clean.

   Everything animated is behind a reduced-motion guard: the orbit in the hero
   is decoration, and decoration must never be the reason someone cannot use
   the page. */
