OK, I found the issue is that base: 'docs' works fine on development, but it requires to be /docs on previewing. Seems a bit inconsistent. :(

And if server: {open: true} is provided, it will open browser without base which results a 404 page immediately.

server: {
  open: '/docs',
},

see https://rsbuild.dev/config/server/open#serveropen for more details.
