Styles are made on our one blog2video account, so b2v_styles records which workspace made each; only that
workspace sees, uses, edits or deletes it. Built-in styles are read-only here, and "Your Style" (which learns from
every workspace's edits) is never offered. The account-wide style selection, pin and built-in overrides are never
touched (blog2video.DENIED).
