/* ============================================================================
   PORTAL.CSS — Paideia Reports internal/admin portal design system
   Notion-approach refactor (exploration, off the brand guidelines).

   Architecture (one-way dependency: components -> roles -> primitives):
     1. PRIMITIVES  raw scales, no meaning
     2. ROLES       semantic tokens; the ONLY thing components may read
     3. COMPONENTS  built on roles

   Dark mode is architected-for: redefine the role block under
   :root[data-theme="dark"] (stub at the bottom) — components never change.
   Self-contained: the admin portal depends on this file only, not app.css.
