-**Phase 1 (this benchmark):** Run everything on CPU with the original BBOB functions
-to find the best PSO configuration that matches established optimizers on convergence.
-
-**Phase 2 (next):** Take the winning config, switch `CPU()` → `CUDABackend()`,
-scale to 10⁵+ particles, and show the same convergence in a fraction of wall time.
