How it works
Expand comma lists and integer ranges, then form products with the left group as the outer loop. Multiply matrices in declared order; the rightmost operation acts first on a coordinate.
The example translates (1,2,3) by (10,0,0), then rotates 90° about Z, producing (−2,11,3). Reversing the operation order gives a different result.
Limits
Extracted metadata only: no CIF/atom expansion, crystal-cell conversion or biological assembly validation. Supports up to eight nonnested groups and 5000 products. Missing operation IDs remain unknown; duplicates stay visible. Coordinates keep the supplied Cartesian units. Finite arithmetic only; duplicate JSON keys reject.
