   The server pages' components (m373 C1; trimmed to them in m401-05): shadcn as the spec, rebuilt in plain
   CSS on Parcells' tokens (static/tokens.css, light then `.dark` on <html>, or the device's theme without
   script). No new hue here: every colour below reads a charte token. Loaded after static/page.css by the
   Jinja pages of templates/ that use these classes (sign-in, invitation, no workspace, the 404); the app
   page draws its own with the React shell's shadcn components (web/src/components/ui), never this file.

   Only the classes templates/ uses stay (`git grep 'ui-' templates/`): button, badge, field label, input
   group, alert, collapsible, the door's account row, the not-found page. States are data attributes as in shadcn: data-variant, data-size,
   data-invalid, data-disabled.
