# The build happens here because the server runs out of memory during
# `strapi build`. That build is only the admin panel (build/) - static
# JavaScript and CSS, no native binaries and no secrets baked in - so a Mac
# build runs on the Linux box unchanged. The API itself runs straight from
# src/, which the server pulls from GitLab at the same commit.
#
# The package is stamped with the commit it was built from; deploy:prod
# refuses to ship it if you have moved on since.
