One command, zero config, and only the client ever bundles: v8 server
code is plain ESM that Node runs as-authored, so there is no server
build to rot (the lesson of v9).
- start: Vite middleware mode + HMR with per-request streaming SSR via
ssrLoadModule; a virtual client entry generates the browser glue so
the user writes exactly one isomorphic module (plan decision D5).
- build: client bundle via Vite 8/Rolldown, manifest-derived route
assets in dist/bankai.json, service worker built with the precache
list injected (choo-service-worker convention, manifest edition),
brotli+gzip precompression of every text asset.
- serve: immutable caching + precompressed negotiation for hashed
assets, 103 Early Hints (res.writeEarlyHints) with the route's assets
before every page, streaming SSR, and a window.initialState tail with
script-breakout-safe serialization and choo internals filtered out.
- inspect: raw/gzip/brotli size report.
Integration tests drive the real counter example through build and
serve, asserting the 103 interim response at the HTTP level.
