# baseHref comes from angular.json (docker configuration = "/app/"). Do not pass an
# absolute --base-href here: it bakes a hostname into the bundle and forces a rebuild
# whenever the public URL changes.
# setup.sh / setup.bat build these apps with `ng build --configuration=docker` and
# nothing else. update-version.js is not on master (only on origin/dev and
# origin/development) and would be a no-op in the image regardless: it stamps
# environment.ts/prod/demo/uat/local/preprod, none of which the docker configuration
# uses, and writes ../b2g_digitall/config/app-version.json - a path outside this
# build context. The digitall backend reads that manifest from its OWN repo.
