    # Apple Silicon only: Apple's fused MPSGraph SDPA, the AUTOMATIC attention
    # backend on MPS. The marker installs it on Apple Silicon and prunes it
    # everywhere else (Linux/CUDA), so it is a hard requirement exactly where it
    # is the only viable attention kernel. Requires torch>=2.11 (within the
    # torch~=2.7 floor); the resolver forks torch to >=2.11 on macOS.
