Create a complete creative brief and script for a 30-second promotional video optimized for Twitter/X, designed for maximum engagement on a mute-first, autoplay platform.

CREATIVE DIRECTION (follow strictly):

Seconds 1-3 — Thumb-Stopping Hook
Goal: Prevent the scroll. You have under 2 seconds of real attention.
Use ONE of the following:
- A bold visual disruption (unexpected color, motion, or scale)
- A text overlay with a provocative statement or question
- A surprising before/after or transformation tease
Rules:
- Must work WITHOUT sound (85% of Twitter video is watched muted)
- No brand logo yet — earn attention before asking for recognition
- No slow fades or gentle intros — start at maximum energy

Seconds 4-15 — Problem and Payoff
Establish the audience's pain point or desire in 2-3 seconds.
Introduce the product/service as the clear resolution.
Show, don't tell — prioritize visual storytelling over narration.
Use fast-paced cuts every 2-3 seconds to maintain engagement.

Seconds 16-25 — Proof and Depth
Demonstrate credibility through ONE of:
- Product in action (real use case)
- A key result, metric, or transformation
- Social proof (testimonial snippet, user count, rating)
Continue the quick-cut pacing. Each shot should add new information.

Seconds 26-30 — CTA and Brand Lock-Up
Deliver one unmistakable call-to-action as both text overlay and voiceover.
Display logo, brand name, and optional tagline.
Final frame should be clean and hold for at least 1.5 seconds.

OUTPUT CONSTRAINTS:
- Provide a full shot-by-shot script with: timestamp, visual description, text overlay, and voiceover/audio for each segment
- All critical information must be communicated visually (captions/text overlays) since most viewers will not hear audio
- Spoken script must be natural and fit within 30 seconds when read aloud
- Keep text overlays to 8 words or fewer per screen

FORMAT AND PRODUCTION:
- Aspect ratio: 9:16 vertical (mobile-optimized)
- Captions: Burned-in, bold, high-contrast (not auto-generated)
- Pacing: Minimum 10 cuts in 30 seconds
- Audio: Energetic background track + clear voiceover
- Final deliverable: Shot list table + full voiceover script
