/* Duet UI: the design tokens and shared components of the account surfaces, which are the
   sign-in family (views/auth-shell.html, plus duet-auth.css) and the account portal
   (pkg/portal/v2, plus duet-portal.css).

   The values are the post-login plans page's (views/plans-feature.html), so /plans, the
   upgrader, sign-in and the portal read as one product. The token names match the marketing
   site's copy of the same palette (DuetWeb/css/duet-tokens.css) so the two files can become
   one later.

   Scoped to .duet-ui, which sits on <html>, never bare :root: the portal still loads Bulma
   (static/css/main.css) and the already-redesigned pages beside it (the plan upgrader's
   .pu-*, the cancel flow's .gs-*) keep their own tokens.

   Light here. The portal redefines these tokens for its dark theme (duet-portal.css,
   html.dp-root); the sign-in pages stay light. Components therefore take every colour from a
   token, never a literal that only works on one background.

   Specificity rules, so this layer and Bulma never fight:
   - element defaults live in duet-auth.css / duet-portal.css under :where(), which adds
     no specificity, so any class (ours, Bulma's, .pu-*, .gs-*) still wins;
   - components are single classes with a dp- prefix (nothing in Bulma starts with it);
   - no bare rules on state classes (.active, .is-active, .valid, .expanded) — the upgrader
     and the cancel modal toggle those on their own elements. */
