/* Clean light dashboard: white cards on a cool grey page, hairline borders,
 * soft one-pixel shadows, one blue for the primary action.
 *
 * Tokens first, components after: every colour below is a role, not a one-off
 * hex, so the whole app can be re-themed by editing this block alone. No web
 * font is fetched — the CSP is default-src 'self' with no font-src, so a Google
 * Fonts link would be blocked — and the system UI face is used on purpose.
 *
 * The same CSP has no style-src, which means the browser refuses a
 * `style="..."` attribute outright. Anything that would have been written
 * inline is a class here instead. */
