 ## Operations Notes
 
-- `vercel.json` disables Git-based Vercel auto deployment
-- the app exposes `/health` for deployment verification

+- the app exposes `/health` for CI deployment verification
 - Docker runtime uses the Node server for app and API delivery
 - CI and release jobs depend on repository secrets for external integrations
