Dockerfile.stockholm clones github.com/krahl/soundcork-stockholm-app at build
time and installs the required tools (prettier, patch, unzip, jq). No pre-built
image is published upstream, so users must run `make build-stockholm-image` once
before `make prepare-stockholm`.
`make prepare-stockholm` runs the upstream entrypoint logic (extract zip,
run prettier, apply patches) via a volume-mounted docker run, stopping before
`exec java` so we only collect the processed stockholm/ output. The Go service
then serves that directory directly with no patching required at runtime.
Prerequisites: Docker with internet access, and stockholm_zip/stockholm.zip
(Stockholm source zip placed manually — tracked directory, zip gitignored).
