/* ============================================================
   Notifications UI — Sino + Inbox + Popup (caixinha do usuário)
   Fluxo B3. Padrão VIP/premium, tokens em theme.css.

   IMPORTANTE: notificação NÃO é gated por billing_enabled — aparece
   sempre que o usuário logado tiver itens. O JS só injeta estes
   elementos para usuário autenticado.

   Idiomas visuais reaproveitados:
     - overlay com blur + scale-in     — .plans-modal (billing-ui.css)
     - tokens gold/green/warning       — theme.css
