/* Kailora Admin — internal operations UI.
   Modern, fast, accessible: bold system-stack typography, a vibrant indigo
   accent over clean white space, layered depth (soft shadows + gradient
   sheens) for a subtle 3D feel, and smooth scroll-driven reveals that are
   fully disabled under prefers-reduced-motion. No external assets — the CSP
   only allows same-origin, so everything here is self-contained. */
