## Title

    Proposed fix: [bitsandbytes] Warning "No prebuilt binary for CUDA X.Y, loading CUDA A.B instead" / BNB_CUDA_VERSION override silently pinning a wrong library

## Body

    Recommended action: Unset BNB_CUDA_VERSION unless intentionally forcing; if set, use digits only (128 for 12.8) and a version that ships in the wheel.
    
    Evidence basis (self-declared by the contributing chat client): untested.
