# context ever includes it — .dockerignore is the first line of that.

# `npm run doctor` — the config doctor for the terminal (#521). It is the tool
# for the case where the app will not start, so it has to be in the runtime
# image rather than only in a checkout. Node 22.18+ strips the types itself,
# so this is the whole of it: the entry point, every module it imports at
# runtime, and js-yaml, which the standalone bundle inlines rather than leaving
# on disk. The standalone build copies package.json verbatim, so the script
# entry is already there. scripts/__tests__/doctor-image.test.ts walks the
# import graph and fails when a module of it is missing from this list.
