+The VitNode website went from 13.1 MiB to 6.6 MiB gzipped. Keep `keep_names` off: some server code sends functions to the browser as source text (the theme and scroll restoration scripts), and esbuild's name-keeping helper turns them into calls to a function the browser does not have, so every page the Worker renders fails with `n is not defined`. Turn `upload_source_maps` off too: a real deploy uploads the bundle's source maps unless told not to, and a large app's maps pass Cloudflare's 60 MiB limit (error `10021`), which a dry run does not check.
 
 If the app prerenders pages, also set `"assets": { "html_handling": "drop-trailing-slash" }`. A prerendered page is written as `page/index.html`, and Cloudflare otherwise redirects `/page` to `/page/`.
