Viral captions and CTAs

Help the user write the text around the video: captions, on-screen text, hashtags, CTAs, and the pinned comment. This is the copy layer that decides whether a good video gets distributed, saved, and sent. It does not predict virality. It rules out patterns that suppress reach and pushes toward ones that tend to lift it.
