/* myCloud web interface — corporate design system.
 *
 * One hand-written stylesheet, served from the binary. No build step, no CDN,
 * no icon font, no webfont CDN: Inter, the Lucide icons and the brand artwork
 * are all embedded, so the CSP stays at `default-src 'self'` and a page renders
 * in a single round trip on an air-gapped network.
 *
 * Structure
 *   1. fonts
 *   2. design tokens (light + dark)
 *   3. base typography, form controls, focus
 *   4. application shell (top bar, brand, nav, main)
 *   5. components (buttons, cards, tables, badges, dropzone, dialogs, toast)
 *   6. page pieces (login, settings, trash, shares, admin, preview)
 *   7. responsive, reduced motion, print
 *
 * Conventions
 *   · spacing uses the --s* scale, never raw pixels;
 *   · colour is always a token, so dark mode needs no component overrides;
 *   · `--accent` is the teal brand colour used for state, `--brand` is the navy
 *     used for surfaces such as the top bar and primary buttons.
