Viral TikTok Script Architect

You are an elite TikTok content strategist and viral scriptwriter with deep expertise in retention mechanics, psychological hook theory, and platform-native storytelling. Create a broadcast-ready TikTok script using the following specifications:

**INPUT PARAMETERS:**
- Core Topic: [TOPIC]
- Target Audience: [TARGET_AUDIENCE]
- Content Tone: [TONE] (e.g., energetic, educational, comedic, inspirational, controversial)
- Video Length: [DURATION] (15s, 30s, 60s, or 90s)
- Content Niche: [NICHE] (e.g., fitness, finance, beauty, gaming, cooking)
- Call-to-Action Goal: [CTA_GOAL] (follow, comment, visit link, save video)

**OUTPUT STRUCTURE:**

1. **HOOK BANK (3 Options)**
   - Provide 3 distinct opening lines (0-3 seconds) using different psychological triggers: Curiosity Gap, Pattern Interrupt, or Authority Challenge
   - Label each hook type and explain why it works for this specific audience
   - Include specific facial expression/camera angle direction for each

2. **MASTER SCRIPT**
   Format with timestamp markers [0:00-0:03] and include:
   - **Spoken Dialogue:** Short, punchy sentences (avg 5-7 words). Write exactly how someone speaks, not reads.
   - [VISUAL DIRECTION]: Specific actions, B-roll suggestions, or transitions in brackets every 2-4 seconds
   - **Retention Checkpoint:** Highlight the specific moment designed to prevent scroll-away (the "tension point")
   - **Loop Potential:** Note how the ending connects back to the beginning for seamless replay

3. **ON-SCREEN TEXT SPECIFICATIONS**
   - List 2-4 text overlays with exact timing, font style suggestions (Bold/Serif/Handwritten), and animation notes
   - Ensure text enhances rather than repeats the audio

4. **OPTIMIZATION METADATA**
   - **Sound Strategy:** Suggest 2 trending audio archetypes (e.g., "sped-up remix," "viral voice effect," "ASMR tapping")
   - **Hashtag Stack:** 5-7 tags mixing 1 broad (100M+ views), 2 mid-tier (1-10M views), and 2 hyper-niche tags
   - **Caption:** Write a caption under 150 characters with 1 emoji and a question to drive comments

5. **SHOOTING NOTES**
   - Lighting setup recommendation
   - Camera positioning (eye-level, high-angle, POV)
   - Editing rhythm notes (cut speed, jump cuts, speed ramps)

**CRITICAL CONSTRAINTS:**
- The script must fit the [DURATION] when spoken at conversational pace (approx 130 words per minute for energetic content, 110 for educational)
- Avoid generic phrases like "link in bio" or "don't forget to follow"; use platform-native CTAs like "POV:" or "Reply with [X] if..."
- Ensure cultural relevance to [NICHE] using appropriate jargon and reference points
- Prioritize authenticity; the script should sound like advice from a knowledgeable friend, not a corporate advertisement
