/* ==========================================================================
   Login page — split layout (video left, form right)
   Page-specific rules only; linked after base.css from
   templates/registration/login.html. Uses --s- tokens throughout so the
   right (form) panel follows light/dark theme automatically. The left
   (video) panel's overlay/text colours are deliberately fixed dark/white,
   not token-driven — they composite over arbitrary video frames, not
   themed UI chrome, the same choice Monti's equivalent page makes.
