Memory-bounded QSMnet via overlap-tiling — the fully-convolutional U-Net run patch-by-patch (for 32-bit WASM, where whole-volume qsmnet overflows the heap on clinical data). The dataset normalization is applied per value inside the tile loop and the net’s pool depth requires a /16 patch. Approximates whole-volume up to tile-boundary error; see crate::inversion::tiled.
