   NUTRILIFT — Diet Validation Popup (redesign)
   Sistema unificato per i 3 popup di validazione dieta:
     data-sev="medical"   -> rosso   (violazioni mediche / allergie)
     data-sev="forbidden" -> arancio (incompatibilita' gravi)
     data-sev="warning"   -> giallo  (avvisi non bloccanti)
   Usa i token di theme.css: si adatta automaticamente a light/dark.
   Carica questo file DOPO modal.css in index.html.
