/* ==========================================================================
   RegiFarm — Design system del pannello web (app shell + componenti).
   Condiviso da tutte le pagine di /app/*.html e da /admin.html.

   Regole del progetto rispettate qui:
   - nessun @import, nessun font remoto, nessuna dipendenza esterna (CSP-safe);
   - nessun selettore :has() (supporto non garantito, ha gia' causato un bug);
   - mobile-first: le regole base valgono per il telefono, poi si sale;
   - il body non scrolla MAI in orizzontale: ogni tabella sta in .table-wrap.

   Token: identici a website/index.html (stessi nomi, stessi valori) + i token
   di stato che nel sito erano hardcoded.
