Set Clip Creator

Who made this clip — a fact about the video, not about its timeline.

Its own route for the same reason review has one: it carries no segments, it must not collide with a card someone else is mid-drag on, and folding it into the save would mean every tag write had to restate the credit or drop it. So no version bump and no version check.

It does touch ssSavedBy and ssUpdatedAt, unlike review — crediting a creator IS a change to what the feed serves, so the card should say who changed it and when.
