/**
 * AMCHP login skin — built from the portal design prototype.
 *
 * Palette and metrics are lifted from the prototype's :root, not invented.
 * The markup is core wp-login.php; everything below either styles what
 * WordPress already outputs or positions the two blocks injected via the
 * login_form hook. #loginform is the card, so it survives an error notice
 * appearing above it.
