qft-infinite-sweep.mjs — workshop the cartesian grid as INFINITE
space: wide/deep/shallow slabs + camera pushed into the lattice +
exaggerated perspective, so the field bleeds off every edge and
rushes to a vanishing point rather than reading as a closed cube.
Usage: node tools/qft-infinite-sweep.mjs [size]
