/* ── Motion Logo (Transparent Video) ── */
/*
  FIX for "black background" issue:
  The navbar starts fully transparent (over dark hero content).
  Transparent WebM composited over dark = looks black.
  Solution: give the anchor a white pill background. The video sits
  on white, so mix-blend-mode:multiply erases the cream video background
  perfectly (cream × white = invisible). Works in all scroll states.
