1. // hl:http1 — HTTP response wrapper (file-as-class: Response)
2. // Split from the former multi-class server.hl (mission 027).
3. // The file root IS the constructor (mission 052 — `__construct` is gone).
4. // Construction is positional: `new Response(body)` or
5. // `new Response(body, { status = 404 })`. Positional args bind to properties in
6. // DECLARATION order, so `body` and `options` must stay the first two
7. // declarations; the run body below folds `options` into status/headers.
8. // A Bytes body is sent raw, byte for byte (ticket #88) — what an app stored from
9. // `req.bytes` can be served back — and says application/octet-stream unless the
10. // headers name a type.
