# Development overlay — hot-reload for backend and web.
# Usage:
#   docker compose -f docker-compose.yml -f docker-compose.dev.yml up
#
# Both services mount local source directories so edits are reflected immediately
# without rebuilding the image. Requires node_modules to exist locally
# (run the matching root install first, for example `pnpm run install:common-plat`).
