Next.js 16 App Router pages mixing static and dynamic content — Partial Prerendering (PPR) under the Cache Components model. Covers enabling it with cacheComponents (the removed experimental.ppr / experimental_ppr flags), the dynamic-by-default rendering inversion, the Suspense static-shell/dynamic-hole boundary, the 'use cache' directive (automatic keys, cacheLife/cacheTag, children/action pass-through, runtime values as props, serverless durability), async runtime APIs and connection() for non-determinism, page composition from a single hole to parallel dashboards to streaming a Promise into a Client Component with use(), and forms/wizards with updateTag read-your-writes and Activity state preservation. Triggers on PPR, cacheComponents, 'use cache', Suspense streaming, partial prerendering, or static-shell work even when not named explicitly.
