+- If backend mode is not explicitly set and Vulkan-runtime backend loading fails, wrapper auto-falls back to `dx12_bridge` on Windows and Linux.
 - `dx12_bridge` is opt-in.
 - On Windows: `dx12_bridge` performs DX12/Vulkan preflight, then loads the first runtime library exposing the required FSR3 dispatch exports.
 - On Linux: `dx12_bridge` is enabled for wrapper runtime compatibility mode and uses Vulkan dispatch symbols in this build.
