/* AI Usage Tray - remote view.
   Light and dark are two hand-picked palettes, not an inversion of one another.

   Theme resolution:
     no data-theme         -> follow prefers-color-scheme (the "Auto" mode)
     data-theme="light"    -> stay light even on a dark system
     data-theme="dark"     -> dark everywhere
   The dark tokens live in two blocks with identical bodies: the media query
   (Auto) and the explicit attribute. Keep them in sync when editing. */
