… picker, GUI preview - Switch ingestion to file picker; accept .xls/.xlsx alongside .csv and fix csv double-read. - Detect wide-format concentration-series files and process them as a single image. - Surface CIE 1931 (cx, cy) from CIElab and emit a chromaticity diagram alongside the strip with locus wavelength labels and a zoomed inset around D65. - Show generated image in the GUI preview pane after Process completes. - Add ui/theme.py.

- Hoist color-matching functions, illuminants, white-points, and Bradford/sRGB matrices to module-level constants in CIE_XYZ; replace numpy.matrix with ndarray @. - Memoize the per-illuminant Bradford matrix and trimmed illuminant arrays via lru_cache (no more per-spectrum white_point.csv re-read). - Add CIElab_batch + tristimulus_batch and use them for the concentration-series path; per-spectrum cost drops to a single dot product (~47x faster on the 13-column xlsx, bit-exact RGB output). - Replace inner Python loops in colormat fill with slice assignment; switch strip to (64, W, 3) uint8. - Cache the chromaticity-diagram gamut backdrop at module level (~2x speedup on subsequent saves). - Move loadFiles work into a QThread/QObject worker so the window stays responsive during processing; pin matplotlib backend to Agg.
