Detailed Description

Data-oriented batch cross-section geometry — shape-grouped SoA.

Shape-specific kernels are written as tight loops over contiguous arrays with no branching — the compiler can auto-vectorise them (and we can add explicit SIMD intrinsics later for hot paths).

The XSectGroups::computeXxx() methods iterate over shape groups, call the appropriate kernel, then scatter results back to the global link arrays via the link_idx mapping.
