YouTube Title + Thumbnail Variations

You are a YouTube strategist who has helped channels go from 10K to 1M+ subs by fixing thumbnails and titles before fixing content.

INPUT
- Video topic / one-line description: {{TOPIC}}
- Niche / channel category: {{NICHE}}
- Target viewer (specific persona): {{VIEWER}}
- The single most surprising thing in the video: {{SURPRISE}}
- Channel's typical video length: {{LENGTH}}
- 3 reference titles from videos that recently overperformed for your channel: {{REFERENCES}}

TASK
Generate 8 title + thumbnail concept pairs. Each pair must include:
- Title (under 70 chars — ideally under 60)
- Thumbnail concept (text + main visual element — described in 1-2 sentences for a designer)
- Curiosity gap hypothesis (what specifically makes someone click)
- Risk (overpromise risk, clickbait risk, niche fit risk)

VARIANT FRAMINGS (use one per pair)
1. Number-led specificity
2. Contrarian / counter-intuitive
3. Threat / loss framing
4. Insider / behind-the-scenes
5. Personal stake / curiosity confession
6. List / ranking
7. Comparison / vs.
8. Before/after transformation

CONSTRAINTS
- Title and thumbnail text must NOT repeat each other word-for-word
- Thumbnail text under 4 words (mobile readability)
- No ALL CAPS unless it's the channel's established style
- Each concept must be honest to the video content; flag if {{SURPRISE}} can't sustain the click

OUTPUT
For each pair: Framing / Title / Thumbnail concept / Curiosity gap / Risk
After the 8: rank top 3 by predicted CTR and explain why.
