/* Adviso design system — catalog + shared component styles (see /design).
   Served from Adviso.Web wwwroot; used on /design AND shared app-wide
   (btn-*, badge-*, card, form-input, alert/chip/list/toggle/pager/step*/empty/
   skel/progress/drop/tabs/tab/toast/prose/choice/chevron/input-accent etc.
   are consumed by Login, Sign, VerifyOtp, workspaces, admin, client pages —
   not catalogue-only). Uses the same tokens as tokens.css on :root — do not
   add a second :root here. No global * / body reset.

   /design-only layout chrome (.ds-layout, .ds-float-nav*, .ds-layout-body,
   .adviso-ds-catalog, .adviso-ds-main) is appended at the bottom of this
   file and keeps the ds- marker because it only appears on /design. */
