## Title

    Proposed fix: [conda >= 25.5 (CEP 22)] 'EnvironmentIsFrozenError: Cannot modify '<prefix>'. The environment is marked as frozen.' — installer/distribution marked the env (often base) read-only; create

## Body

    Recommended action: Create and use a separate environment (conda create -n work ...) rather than modifying the protected one; pass --override-frozen only if you own the environment and accept the risk.
    
    Option: Use a new environment [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. conda create -n work python=3.12
    2. conda run -n work pip install ...
    Expected: Command proceeds without the error.
