Files
	fluid.cpp
	Single-switch dispatch from Backend enum to SPH backend implementations.
	fluid.hpp
	Weakly Compressible SPH (WCSPH) fluid solver – public interface.
	heat.cpp
	Heat computation has moved to backends/seq/heat.cpp and backends/omp/heat.cpp. Dispatch happens in fluid.cpp. This translation unit is intentionally minimal – kept for CMake.
	heat.hpp
	Heat transfer parameters for the SPH backends.
	kernel.hpp
	SPH smoothing kernels for 2D WCSPH — delegates to num::SPHKernel<2>.
	main.cpp
	SPH fluid simulation with raylib visualization.
	particle.hpp
	SPH particle data structure.
	rigid_body.hpp
	Rigid body (sphere) for SPH collision and heat exchange.
	spatial_hash.cpp
	SpatialHash is now a header-only wrapper around num::CellList2D. This translation unit is intentionally empty – kept for CMake.
	spatial_hash.hpp
	SPH neighbour search – now powered by num::CellList2D.
