📝 Walkthrough

Walkthrough

Test-only changes: updated a regression test to use the correct element type parameter, and added a comprehensive test case for IdxRange iteration and transform operations including empty ranges, 1D/3D visitation, translation, and stride scaling.

Changes

Cohort / File(s)	Summary
Test Updates test/unit/mem/concepts.cpp	Fixed regression test to compute pitches using the same element type (NonCopyStruct) as the tested MdSpan instead of int, with clarified comments.
New Test Case test/unit/mem/idxRange.cpp	Added comprehensive test case for IdxRange edge cases and transforms, covering empty ranges, 1D/3D iteration order, translation operators, stride scaling, and added #include <vector> dependency.

Poem

🐰 A rabbit hops through index ranges with glee,
Testing each pitch and dimension so free,
From empty to full, in three-D arrays we bound,
Transforms and strides—all correctness is found! ✨
