/* ============================================================================
 * auth.css — shared styles for the chrome-less authentication pages
 * (login, register, two-factor, mfa-setup, change/reset password, accept-invite,
 *  email verification). Loaded by layouts/layout_auth.html.
 *
 * Consolidation note (template-consolidation pilot, 2026-06-08):
 * Every auth page used to inline ~250 lines of near-identical CSS. That block is
 * now centralized here. The animated background gradient is unified to the
 * violet/blue scheme used by 9 of the 10 auth pages (login was the lone red
 * variant). The red accent (var(--color-danger)) is preserved on buttons,
 * focus rings and the logo across all pages.
 *
 * Token-first: values use var(--token, #fallback). The fallback keeps parity
 * even when tokens.css is absent. Genuinely page-unique CSS (OTP cells, plan
 * cards, QR blocks, step indicators, password-strength meters) stays in each
 * page's {% block extra_css %}.
 * ========================================================================== */
