/*
auth.css

QUOI : Famille "authentification publique" (connexion, inscription, mot de passe oublié/reset,
       changement forcé) — carte centrée premium "liquid glass", mobile-first.

COMMENT : Reprend telle quelle la structure de admin/login.css + admin/register.css (classes
          `.login-*`), renommées `.auth-*` et retokenisées sur les jetons publics (--c-*) au lieu
          des jetons admin (--adm-*). admin/login.css et admin/register.css restent inchangés —
          l'admin garde sa propre déclinaison si besoin plus tard.

OÙ : Chargé par les 6 gabarits publics de la famille auth, à la place de styles/admin.css.

POURQUOI : docs/superpowers/specs/2026-07-15-refonte-formulaires-publics-design.md — ces pages sont
           100% publiques mais empruntaient tout le bundle admin pour une poignée de classes.
