Web-shape HTTP carrier: a `node:http` server routing `/api/*` to an injected fetch-shaped handler (node:http ↔ WHATWG bridge with SSE streamed out chunk by chunk) and everything else to static file serving with the step1-locked semantics — traversal outside the dist root is 403, any miss falls back to `index.html` with HTTP 200 (SPA routing), unknown extensions ship as octet-stream, non-GET/HEAD is 405.
The package has zero workspace dependencies on purpose: the handler arrives by structural typing (`{ fetch: typeof fetch }`), so `webserver ← runtime` is a runtime injection relationship, never a package dependency. Callers supply both the bind `host` and `port`; port `0` requests an OS-assigned port and the running handle reports the assigned value. `dsh web` defaults to `127.0.0.1` and accepts `--host 0.0.0.0` for deliberate network access. Web (browser) shape only — Electron loads dist over `file://` and carries fetch over an IPC bridge, not this server. This package never prints; the URL line belongs to the shell.
The package has zero workspace dependencies on purpose: the handler arrives by structural typing (`{ fetch: typeof fetch }`), so `webserver ← runtime` is a runtime injection relationship, never a package dependency. Callers supply the bind `host`, `port`, and positive `maxRequestBodyBytes`; port `0` requests an OS-assigned port and the running handle reports the assigned value. The API bridge returns 413 before buffering a declared oversized body and keeps chunked-body buffering within the same cap. `dsh web` derives its default cap from the configured aggregate image limit plus base64/envelope expansion and accepts `--max-request-body-bytes` as an explicit override. It defaults to `127.0.0.1` and accepts `--host 0.0.0.0` for deliberate network access.

Client-disconnect detection hangs off the **response** `close` event, not the request: since Node 16, `IncomingMessage` `close` fires as soon as the request body is consumed (immediately for a bodyless GET), which would abort every SSE stream right after open. `RunningWebServer.close()` pairs `close()` with `closeAllConnections()` because SSE connections never end on their own.
