The _comment_atlas_goldens key inside scenarios{} hit _print_list's .get() on a bare String (reproduced: Invalid call on String at visual_capture.gd:699). Moved to a top-level key alongside resolution/golden_dir; _print_list now also skips _-prefixed and non-Dictionary entries so future comment keys cannot crash it. Verified: --list runs clean, JSON valid.
