/* auth.css — Guardian Command login wall + loading state
 *
 * The login wall is the user's first impression of the platform —
 * the visual language here has to match the dashboard exactly so the
 * sign-in step feels like part of the product, not a hand-off to a
 * third-party form. Same Inter + Bebas Neue + JetBrains Mono trio,
 * same near-black surfaces, same electric blue accent.
 *
 * Tokens are scoped to this stylesheet — the dashboard's --gc-*
 * tokens haven't loaded yet at login time, so auth.css carries its
 * own --auth-accent + --auth-accent-hover that line up with the
 * canonical electric blue (#2F6BFF / #5B9BFF).
