/* public/css/docs.css — Public /docs/api reference page.
   Server-rendered reference for the productionised /api/b2b/verify endpoint.
   Reads live tier rates, quotas, and SLA flags from db/api-keys.js via
   routes/docs.js, then renders a copyable markdown-style page that mirrors
   the partners-landing marketing layout. No JS portal / no client hydration —
   static enough that grep on the response is a useful smoke test. */
