/* =========================================
   PLATFORMA DESIGN SYSTEM (FASE 5 — DS.3 + DS.4 + DS.5 — 2026-05-08)
   -----------------------------------------
   Component CSS that binds to tokens declared in platforma-tokens.css.
   This file deliberately stays small + focused — it covers the NEW DS.*
   primitives (icon, page-banner, kpi-card, badge variants). Larger
   subsystems (forms, alerts, buttons, tables) live in their own files.

   Sections:
   1. Icon (DS.3)
   2. Page banner (DS.5)
   3. KPI card (DS.4)
   4. Badge / chip variants (DS.4)
   5. Button-row (DS.4)
