# uv owns the environment for this repo: it creates the .venv, resolves
# the uv + Cargo workspaces, and builds the `dynbem` Rust extension via
# maturin so `import dynbem` works after this script finishes.
#
# Works on Linux / macOS / Windows (git-bash, WSL). Windows callers can
# use the setup.cmd wrapper, which runs `uv sync` directly (no bash
# required).
