/* ─── Auth zone ────────────────────────────────────────────────────────────
 * Loaded by App.razor unconditionally. Only takes effect when an auth page
 * (using AuthLayout) is rendered — every rule is scoped to .auth-* classes
 * that AuthLayout produces.
 *
 * The auth zone is archetype-neutral: same dark glassmorphic look across
 * every realm, with --realm-hue / --realm-hue-2 set on .auth-page providing
 * the brand-tinted backdrop wash and accent.
