/* VDrop — design tokens & shared UI
   One committed mood, not a light/dark split: a looping ambient video —
   a glowing drop adrift in the dark — sits fixed behind every screen, and
   the UI floats over it as frosted glass. A card that flips to a "light"
   palette over a dark video makes no sense, so the palette below is the
   only one; it IS the dark palette from the old two-theme version. */
