The whole build directory is checked in as one file called build.zip.
That keeps it easy to create a new build without having to git add
new files. The ./build/ directory is still git ignored.
This build is created with ./make_build.sh.
The reason for checking in the whole build is to avoid having to run
yarn run build on the server since it's very CPU intensive on a cheap
shared server.
