/**
 * Schermate di autenticazione (login, registrazione, recupero password, OTP)
 * e pagine di errore pubbliche.
 *
 * Impianto: una card centrata su uno sfondo astratto generato interamente in
 * CSS a partire da --bs-primary — nessuna immagine da scaricare e ogni tenant
 * eredita la propria palette.
 *
 * Va caricato DOPO theme.css. Tutte le classi hanno prefisso .auth- per non
 * collidere con lo stile storico (.login-wrapper, .login-content, …) ancora
 * usato altrove.
