Add color pixel density checks to cv_graphic_detect.py Pass 1: - density < 20% → skip (text strokes are thin, images are filled) - density < 30% + height < 4% page → skip (colored text line) This fixes green headings (Insel, Internet, Inuit) being removed as graphic regions, which also caused word reordering in lines.
