Introduce structure types with named members, sequential offsets, and size. Unit-tested via Type.structureMembersHaveOffsetsAndSize. Full language surface (struct definitions in CSNB, member access codegen) remains the next transplant from finish-for-git.
Use natural alignment and trailing pad for structure members, treat pointer-to-structure as pointer-only, and strengthen structure Type tests.
Reject incomplete and duplicate members, accumulate layout size in long long with overflow checks, and cover trailing pad / array stride.
