Detailed Description

Demonstrates k-space helper functions eliminating code duplication.

This example shows the before-and-after comparison of using the new k-space helper functions. The same ~30 lines of k-space calculation code was duplicated across 4+ examples (04_diffusion_model.cpp, 12_cahn_hilliard.cpp, etc.), totaling 120+ lines of duplicated code.

The new helpers eliminate this duplication while maintaining identical computational results (zero-cost abstraction).
