+<h2>METHODOLOGY</h2>
+<p>Each benchmark is run with the <a href="https://github.com/huggingface/kernels-benchmarks">Kernels Benchmarking Framework</a> and follows these principles:<br />
+- a reference implementation (usually PyTorch native) is included for baseline comparison<br />
+- multiple input sizes and batch sizes are tested to reflect real-world usage<br />
+- runs are repeatable via python virtual environments and documented dependencies<br />
+- results are collected and visualized using standardized scripts  </p>
