Engine: - preprocess() accepts conversion_mode (bw/grayscale/color), invert, mask_regions - B&W: full pipeline → binary; Grayscale: skip threshold → 8-bit; Color: skip grayscale → BGR - routes.py forces VTracer for non-binary modes, sets colormode appropriately - potrace_trace() accepts turnpolicy param mapped to potrace constants - 27 new tests in test_modes.py (modes, invert, masks, params, vectorization) App: - Mode selector tabs (B&W | Grayscale | Color) in ImportConvert - Invert toggle (B&W only) - ParameterSliders rewritten: grouped sections, 10+ mode-aware controls - Debounce reduced from 300ms to 100ms - Preview background changed to white - Preset JSONs updated with turnpolicy, color_precision, layer_difference defaults Tests: 126 app + 234 engine = 360 total, all pass. Zero TypeScript errors.
