parallel_for_cpp_core: ThreadPool reutilizable con parallel_for(begin, end, fn) y parallel_for_chunks(begin, end, fn(tid, lo, hi)). Captura excepciones del worker y las relanza en el caller. Pareja CPU del despacho GPU para Monte Carlo multi-core cuando dispatch GPU no compensa. slider_cpp_core: wrapper de ImGui::SliderFloat/Int/Double con label muted arriba, tokens (primary grab), full-width. Variantes float, float_log (logaritmico), int, double. Para los calculadores que tienen 15-30 sliders cada uno y se beneficia del estilo consistente.
