+# What must never enter the build context.

+# There was no .dockerignore at all, so every one of these was being uploaded to
+# the Docker daemon on each build and then copied into the builder image by
+# `COPY . .`.

+# `.git` is the one that matters for speed — it carries the entire history, and
+# it grows forever while being worthless to a build. The rest is correctness:
+# `dist` and `node_modules` from a developer's machine would be copied in and
+# then overwritten by the build, but only after being transferred, and a stale
+# `dist` copied over the fresh one is a genuinely confusing failure.
