• [nitpick] Consider using Python's built-in sum() function instead of numpy.sum() to count booleans. This change would reduce external dependency overhead while achieving the same result.

count_gallery_headings = np.sum(['https://pyfar-gallery.readthedocs.io' in line for line in lines])

.github/workflows/has_label.yml:22

• The updated label check only verifies that some label exists instead of enforcing a version label format. Confirm if this change is intended or if it may affect version label validation.
