YouTube thumbnail copy — 3 concepts

Generate 3 thumbnail-text concepts for this YouTube video.

Video title: {{title}}
The viewer + their pain or curiosity: {{viewer_pain}}

Brand colour and an accent colour: {{colours}}

Return 3 thumbnail concepts. Each one:
1. CONCEPT NAME (e.g. "Big Number", "Before/After", "Faceshock + 3 words").
2. THE TEXT — max 4 words, all caps OR title case (state which), positioned (left/right/centre).
3. WHAT'S IN THE IMAGE — 1 sentence describing the visual + facial expression if face-cam.
4. WHY THIS WINS — 1 line on the psychological hook (curiosity gap / contrast / specificity).
5. WHAT TO TEST IT AGAINST — what existing top-performing thumbnails this might beat or lose to.
