/* ============================================================
   WhatsApp Marketing SaaS — Bootstrap 5.3 custom layer
   The design system is Bootstrap (dark theme) + this thin layer:
   brand tokens (deep-green accent), the gradient brand button,
   the app sidebar, the auth hero, and the few boxes Bootstrap
   has no primitive for (QR box, group checklist, paywall veil).
   Everything else — layout, cards, tables, forms, buttons,
   badges, alerts, progress — is stock Bootstrap classes.
