# mcaxl docs — multi-stage build.
#
# Stages:
#   deps   — install node_modules once, cached by package.json
#   dev    — runs `astro dev` with the source bind-mounted (compose `dev` profile)
#   build  — produces the static site in /app/dist
#   prod   — serves /app/dist with Caddy (static file server, no Node runtime)
