pub fn run_fast_path_timing_study() -> Result<FastPathTimingStudy>Expand description
Run the GPU timing study for the fast-path proxy at 1080p and 4K.
Uses synthetic uniform-colour inputs at each resolution.
Runs warmup_runs iterations before measuring, then averages measured_runs.
Returns measured timings if a wgpu adapter is available; otherwise returns a
study with actual_gpu_timing = false and no entries.
