/* ════════════════════════════════════════════════════════════════════════════
   Synetic Portal — Base Components (#523)

   Built on tokens.css. New vocabulary for patterns that the audit found
   scattered as inline styles. Existing classes (.btn, .card, .m-input)
   are left alone in this PR — their migration to tokens lives in a
   follow-up. This file ONLY adds:

     - Truly new components (.pill, .status-dot, .empty-state, etc.)
     - New modifiers on existing classes that don't conflict (.btn-ghost,
       .card-info / .card-warning / .card-danger left-accent variants)

   Loaded AFTER portal.css so it can layer modifiers cleanly. Loading
   order in index.html:
     tokens.css  (foundation)
     portal.css  (existing styles, gradually migrating)
     components.css  (new component vocabulary — this file)

   Naming convention matches existing portal.css: kebab-case with dash
   modifiers (.pill-success, not .pill--success).

   See docs/UI-DESIGN.md for usage guidance.
