   Billing UI — Trial banner + Plans modal (cobrança Stripe)
   Fluxo B3. Padrão VIP/premium, tokens em theme.css.

   IMPORTANTE: nada aqui aparece enquanto billing_enabled === false.
   O JS (billing-ui.js) só injeta estes elementos quando a flag está on.

   Idiomas visuais reaproveitados:
     - .deletion-banner (faixa abaixo do header) — auth-state.css
     - .account-modal     (overlay + card)        — auth-state.css
     - tokens gold/green/warning                  — theme.css
