# syntax=docker/dockerfile:1.7
#
# Multi-stage Dockerfile matching the warehack-ing services convention:
#   * dev   — Astro dev server with HMR, source-mounted via compose volumes
#   * build — runs `astro build`, produces /app/dist
#   * prod  — Caddy serves the static dist on port 80, plus a /health probe
#
# Pick the stage at compose-build time via APP_ENV={dev,prod} in .env.
