/**
 * auth.css — styles shared by login.html and register.html.
 *
 * Pages reuse the global Brandzyla design tokens (brand palette, Monainn
 * font, shadow-card / shadow-soft) via Tailwind classes. Only the few rules
 * that are awkward or verbose to express as utilities live here, so the
 * cards stay visually consistent with the rest of the site.
