### Live Preview without reloads

See editor changes in the browser within \~100ms via Contentful's Live Preview SDK and React 19 server components.

### Surgical revalidation

### How is caching handled?

Next.js fetch cache + Contentful webhook → /api/revalidate → revalidateTag for surgical invalidation.
