The default output is written to build/client and build/server (RSC builds also add build/server/__ssr_build). The build also writes build/ness-manifest.json, which records the built routes, the cache profiles, and the deployment settings from ness.config.mjs — in RSC mode this comes from Ness's own route tree rather than React Router's build manifest, since RSC Framework Mode does not support a buildEnd hook. Use ness start to serve the completed build.
