/* Mobile-first admin styles. No external dependencies.
   Goals: readable on phones (>=16px text, big tap targets), tables that
   collapse to cards on small screens, light/dark aware with a manual toggle.

   Visual language: calm, crisp, soft depth (Linear/Stripe-dashboard feel).
   Depth + interaction come from CSS tokens (shadows, focus ring, hover tint,
   radii) defined for BOTH themes so nothing is undefined in either.

   Theme resolution:
   - default     -> light values in :root
   - system dark -> dark values, UNLESS the user forced light (data-theme=light)
   - data-theme="dark"/"light" (set by the toggle) always wins. */
