/* ═══════════════════════════════════════════════════════════════════════
   HOME — one screen, no scroll.

   The homepage is a single stage: the claim, one button, one image. Every
   section that used to live below the fold now lives on the page that owns
   it (/platform, /engagements, /security), which is where the links go.

   Everything here is scoped to body.home-single so no other page inherits
   the locked viewport.
