/* ═════════════════════════════════════════════════════════════════════════════
   UTU TOTEM SIGNATURE OS — MAARA TownMesh integration build
   Kenya pride + Lo Shu gate 5 + unity-in-diversity first-contact overlay.
   Safe sensory rule: visual rhythm only; no infrasonic audio emitted.

   Integration note: body.utu-sig-active dark background is intentionally
   SCOPED to .utu-page-root so it only applies on the UTU landing page.
   The corner sigils (#utu-totem-layer) and route pill are always-on globally.
