   Motion — native CSS only, no library, no JS.

   ONE moment, and it is the hero's load. The hero's own elements arrive in a
   short stagger via @starting-style + transition: 420 ms each, last delay
   160 ms, 580 ms in total. Nothing else on the page animates on entry.

   Scroll-driven reveals were removed on 05 Sep 2026 and must not come back.
   They hid every section below the fold from every screenshot this repo took —
   a fullPage capture does not scroll, so the operator's "look at the
   screenshots" gate was looking at a blank page. They also run backwards when
   the visitor scrolls up, and on a phone opened from WhatsApp they read as lag.
   Everything below the hero is painted at load, no exceptions.

   A browser without @starting-style simply shows the finished page.
   prefers-reduced-motion removes the stagger and changes nothing else.
