/* ==========================================================================
   Krignal — v3, "The Meeting"
   One frame, one long scroll, rendered as a real WebGL scene (see
   v3-scene.js): a gold frame around the viewport itself, a vine that
   climbs it and blooms, and two hands that close the last of the gap
   between them. This stylesheet only owns the DOM layer on top of the
   canvas — text, the CTA, chrome — nothing here draws the scene itself.
