# This image holds the Docusaurus toolchain (Node 22 LTS + npm + docusaurus
# deps). It is run via docker-compose to consume a snapshot of the repo's
# markdown content (mounted as `/work/docs`) and produce the static build
# output (mounted as `/work/build` -> host `apps/docs/build/`).
#
# The Bun bytecode-compiled runtime server lives outside this image.
