/* ── Hero gradient sweep ───────────────────────────────────────────────
   Ported from the app's .gradient-hero / .gradient-sweep-active
   (apps/web/src/styles/globals.css) so the two surfaces read as one brand.
   Stops are verbatim; --brand-primary uses the app's dark-theme value.
   This is the ONLY place the brand gradient appears on this page.

   One stop is changed: the app's #6B45D0 violet measures 2.88:1 against this
   page's backdrop, just under the 3.0 WCAG minimum for display text. It is
   lifted 8% in lightness to #7957D4 (3.51:1), hue held at 256deg.

   The app gates the sweep behind a 1s React timer to avoid animating
   through first paint. A CSS animation-delay does the same job here with no
   JS: .hero__h em paints at 200% center from the start, then begins moving.

   background-size:200% + default repeat makes 200%→0% exactly one tile, so
