# Build AND concatenate. b2g_filems_fe is the micro-frontend (package name "micro-fe"):
# concat.js merges runtime/polyfills/main into app/micro-fe.js, which b2g and gMarket
# inject via window.__env.microfeHost. A plain `ng build` emits hashed main.<hash>.js and
# no micro-fe.js, which is why those apps had to load it from the production site.
# --output-hashing=none is required: concat.js reads the unhashed filenames.
