/* tDocs — Cloud drive design system v6
   ---------------------------------------------------------------------------
   Light-first cloud drive: white cards on a tinted page, one blue accent,
   soft elevated shadows, generous radii. Dark is kept as a peer theme so the
   existing toggle keeps working. Legacy variable names (--primary, --bg-panel,
   --radius-md, …) are preserved: templates and app.js reference them inline.
