# Build the static site, then serve it with nginx.

# The build stage needs git: "last updated by" on every page is read from git

# history at build time. Keep .git in the build context (see .dockerignore) and

# make sure CI checks out the full history — a shallow clone has one commit and

# blanks out most authors. Without git the build still succeeds; pages just

# fall back to the file date with no author.

# Verified: builds clean, 76MB image, deep links and git attribution both work

# in the running container. `docker compose up --build` serves it on :8080.
