Every file under assets/ was compressed again on each download, at the low level a request path can afford. They carry their content hash in the name and never change, so the client build now writes a Brotli copy beside each compressible one (postbuild, scripts/precompress.mjs) and production points a browser that accepts Brotli at that copy before express.static serves it. Measured on a production build of 5.1.2, fetching the 652 precached files the way a service worker install does: 16.3 MB -> 13.9 MB on the wire and about 1.0 s -> 0.2 s of server CPU per install. A client without Brotli, a range request and a build without copies are served exactly as before.
