Delete several scenes, timeline clips, stickers and captions in one edit: pass 1 to 200 ids in element_ids. All or nothing: an unknown id, a clip on a locked track, or a locked track a scene's cut would move refuses the whole call, names the first offender, and deletes nothing (unlock it with lock_track, or pass ripple_secondary "none"). Scenes follow ripple_secondary as in delete_element: "shift" (default) removes each deleted scene's time from every lane, keeping later clips in sync; "none" closes the main track alone. The receipt's clips_removed and clips_trimmed count each unlisted clip once, however many deleted scenes it spanned. Listed clips leave gaps (ripple_delete closes one); captions hide reversibly (restore_fillers brings them back).
