docker-compose.dev.yml

# RustaSea development override — hot-reload the workspace app.
#
# Layer on top of the base stack for a live-reload loop:
#
#   docker-compose -f docker-compose.yml -f docker-compose.dev.yml up
#
# The workspace is bind-mounted into the container and `cargo-watch` rebuilds
# and restarts the app on every source change. Named volumes keep the build
# cache and the cargo registry out of the bind mount so they survive restarts.
