-// ──── Driver workaround: per-member SSBO load ────────────────────────────
-// `UIItem it = itemHeap[idx].items[i]` emits an OpLoad of a composite type
-// from a descriptor-heap'd SSBO, which crashes the GPU on the NVIDIA
-// VK_EXT_descriptor_heap path (verified with a 1-float struct repro).
-// Reading individual members works (each becomes OpAccessChain + scalar
-// OpLoad). LoadItem reassembles the struct member-by-member into a local;
-// the rest of the shader then operates on a regular local var.
