/* ============================================================
   Education (role-aware course list) page.
   Shared by desk staff (light theme) and participants (dark theme):
   the same markup + CSS render correctly in both because color comes
   only from --t-* tokens, which the theme layer rebinds per persona.
   Structure in @layer layout, paint in @layer design. Content-named
   classes only — no legacy/appearance names, no hardcoded color.
   Reuses .app-screen and .btn/.btn--primary from elements.css.
   See docs/FRONTEND-ARCHITECTURE.md.
