/* ==================================================================================================================
   usefulweb design system — foundation (tokens, base elements, forms, tables, shared components).
   platform.css adds the page layouts; apps.css the premium-app chrome; account.css the account UI.
   Themes: light tokens on :root; dark tokens when <html data-theme="dark"> (explicit choice, set by the server from the
   uw_theme cookie) or when the OS prefers dark and the visitor has not chosen light. Premium-app workspaces
   (html.uwapp-html) keep their own app themes: there only the platform top bar (.uwapp-bar) follows the site theme.
   The two dark blocks below are
   identical on purpose (tests/platform/theme.test.ts keeps them in sync). All colour pairs meet WCAG 2.2 AA in both
   themes: text ≥ 4.5:1, large text / UI parts / focus ring ≥ 3:1 (docs/ACCESSIBILITY.md "Themes").
   No web fonts are downloaded: the system UI font of each platform, with script-specific fallbacks in platform.css.
