Research direction
Reproduce the reported workload using the createCell/setCellStyle loop for 45,000 cells and autofitColumn across 14 columns. Compare timings for cell creation, styling, and column autofit; done should include a demonstrated performance improvement for the reported operations, with regression coverage if the repository provides a suitable test location.
