The build pipeline, incremental work, and server runtimes.

Build PipelineAn end-to-end tour of how zfb turns your project into a built site.Render ArtifactsThe JSON build artifact zfb writes for each single-region markdown/MDX route — shape, field semantics, and the region rule that decides which routes get one.Incremental rebuildHow zfb's dependency graph limits each rebuild to the pages actually affected by a file change.Dev mode lifecycleWhat happens between hitting save on a .tsx file and seeing the change in the browser — watcher, rebundle, SSR refresh, and the three SSE event types.SSR on a Worker (adapter mode)How a prerender = false zfb page actually runs in production — the two-layer worker output, how Workers Static Assets serves matching assets before the Worker runs, and the AsyncLocalStorage trick behind getCloudflareContext().Build engineHow zfb's crates fit together, why the rebuild is per-page, and what makes a `dist/` write safe.JS runtimeHow zfb hosts JavaScript execution server-side via an embedded V8 isolate, and why the runtime is fixed by the binary.The zudo-react runtimeHow zfb uses one owned runtime to render whole documents and adopt island subtrees.
