Widely used scores emphasize global superposition or distance deviations and are not designed primarily for direct assessment of contact patterns. A fast and flexible contact-area-based alternative is therefore highly relevant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We present CAD-score-LT, a high-performance implementation of the Contact Area Difference score (CAD-score) for superposition-free comparison of macromolecular structures. CAD-score-LT evaluates tessellation-derived contact, binding-site, and solvent-accessible surface areas at atom, residue, and chain levels, and supports selective scoring of substructures, interfaces, and binding regions. The software also provides sequence-guided preprocessing, chain remapping, symmetry-adjusted ligand scoring, local scores output, and clustering. Benchmarking against previous CAD-score implementations on CASP16 oligomer model pairs showed near-identical scores but more than one order of magnitude lower running times, with speedups reaching up to 100-fold for whole-structure scoring and 200-fold for inter-chain interface scoring. Case studies in supplementary material demonstrate utility for large-scale model clustering, analysis of protein\u2013nucleic acid interfaces, and evaluation of protein\u2013ligand docking models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Availability and implementation<\/jats:title>\n                    <jats:p>A repository with the CAD-score-LT software and the reproducible benchmarking and example workflows is available at https:\/\/github.com\/kliment-olechnovic\/cadscore-lt-supplementary-info and archived at Zenodo https:\/\/doi.org\/10.5281\/zenodo.21983528.
