   MSI DESIGN SYSTEM — Accademia di Naturopatia Ippocrate
   -----------------------------------------------------------------------------
   Design system unificato per le interfacce admin della suite
   (Monitor Studenti + Roadmap Didattica + Autovalutazione).

   Estetica: Apple/minimal applicata al contesto naturopatico.
   Molto respiro, tipografia di sistema, gerarchia netta, ombre morbide,
   raggi generosi, animazioni brevi. Accento primario #0071E3.
   Palette secondaria calda (salvia / terra / ocra) riservata ad accenti,
   badge e richiami olistici — mai alle superfici principali.

   Convenzioni
   -----------
   - Tutti i selettori sono prefissati `msi-` e pensati per convivere con
     wp-admin senza combatterlo (nessun override globale, nessun !important
     se non strettamente necessario).
   - Ogni valore cromatico passa da un token in :root. Le trasparenze sono
     derivate dai token con color-mix(), così il dark mode funziona senza
     duplicare una singola regola di componente.
   - Nessun preprocessore, nessun @import, nessun @font-face remoto.
