        Some Gemma4 variants use different head dimensions for
        sliding window (head_dim) vs full attention (global_head_dim) layers.
        When global_head_dim > 256, FlashAttention rejects those layers
        (head_size <= 256 kernel limit), causing vLLM to select a different
        backend for each layer type. This mixed-backend execution produces
        numerical divergence and output corruption.

        The fix detects heterogeneous head dimensions from the model config
        and forces TRITON_ATTN (which has no head_size ceiling) for all
        layers when the user hasn't explicitly chosen a backend.
