/*
 * auth.css — Crew2Sea Identity Pages
 * ─────────────────────────────────────────────────────────────────────
 * Scope: ALL Identity/Account pages (Login, Register, ForgotPassword,
 *        ResetPassword, 2FA, RecoveryCode, Lockout, AccessDenied,
 *        Logout, ConfirmEmail, ConfirmEmailChange)
 *
 * Rules:
 *   1. Every variable references an existing token from app.css / BS.
 *   2. No hex colour literals — only var(--bs-*) tokens.
 *   3. Classes are grouped by layer:
 *        A. Layout shell      — page-level positioning
 *        B. Card              — the white container
 *        C. Brand block       — logo + wordmark + tagline
 *        D. Input helpers     — icon-prefix wrapper
 *        E. Typography        — repeated text styles
 *        F. State pages       — icon + heading for status pages
 *        G. Role selector     — Register page only
 *        H. Footer / meta     — links below card, copyright
 *        I. Modifiers         — .auth-card--center for status pages
 * ─────────────────────────────────────────────────────────────────────
