Shorts title tests get messy when the edit changes too

A note about testing Shorts titles and cover frames while keeping the video edit stable enough to learn from the result.

Shorts title tests get hard to read when the title, cover, opening line, sound, and CTA all change at once. I prefer changing the visible promise first: title, cover frame, and first frame. If the same edit works better with a clearer promise, the video may not need a full rewrite.
