  uv (recommended):
    curl -LsSf https://astral.sh/uv/install.sh | sh

  pipx:

  pip:

Add the relevant tool's bin directory to your PATH, then restart your shell:

  uv:    ensure ~/.local/bin is on PATH (or run 'uv tool update-shell')
  pipx:  run 'pipx ensurepath'
  pip:   ensure the user-base bin directory is on PATH (see 'python -m site --user-base')
