+# docker-compose.yml — One-command dev environment for the app.
+#
+# Key points:
+#   • `volumes` bind-mounts the project root into /app so file changes on
+#     the host are instantly visible inside the container (live reload).
+#   • An anonymous volume for node_modules prevents the host's
+#     node_modules from overriding the container's (they may differ by OS).
+#   • `ports` maps container 5173 → host 5173 so you can open the app
+#     at http://<host-ip>:5173 from any machine on your LAN.
