# Cross-platform development environment for RSScript.
#
# Quick start:
#   docker compose build                                   # build the dev image
#   docker compose run --rm dev cargo run --bin rss -- test --all
#   docker compose run --rm dev bash                       # interactive shell
#
# The repo is bind-mounted at /work, so host edits are picked up immediately.
# Build artifacts and crate caches live in named volumes (not on the bind mount)
# so compilation persists between runs and stays fast on macOS/Windows.
