Sample n_lines parallel scan lines perpendicular to the bars. The bar-normal
direction is angle_deg (degrees from the image x axis, counter-clockwise in
display = row up) or, if None, the dominant gradient direction of the structure
tensor. Lines are spaced evenly over the band fraction of the strong-gradient
region’s extent along the bars (ISO-style 10 scans over 10 %..90 % of the height),
sampled every step pixels by bilinear interpolation over the whole image width.
Returns profiles (n_lines, L), angle_deg, coherence (0..1, how
line-like the texture is), offsets (px across the bars), step and
origin / direction / normal (row, col) so a profile sample s of line
k maps to origin + offsets[k] * normal + s * step * direction.
