<reasoning_process>
1. Identify the primary benefit: what is the ONE thing that makes this product different from alternatives?
2. Lead with the benefit, not the feature: people buy outcomes, not ingredients.
3. Use sensory language where applicable: how does it feel, look, taste, sound?
4. Address the target customer directly: use 'you' and speak to their specific need.
5. Structure: hook (benefit) -> details (features connected to benefits) -> social proof -> CTA.
6. Optimize for scannability: short paragraphs, bulleted features, bold key phrases.

<example>
INPUT: Ergonomic desk chair. Customer: remote workers with back pain. Key feature: dynamic lumbar support that auto-adjusts. Differentiator: moves with your body rather than locking you in one position.

OUTPUT:
Your back shouldn't hurt after an 8-hour workday.
The ErgoChair Pro automatically adjusts lumbar support as you shift positions throughout the day. Most chairs lock you into one angle. This one moves with you: leaning forward for focused work, reclining for calls, upright for deep writing.
What makes it different:
- Dynamic lumbar support that auto-adjusts as you move (not manual knobs you'll never touch)
- Breathable mesh back that stays cool through 10-hour days
- 12-year warranty (most chairs offer 2-5)
'I stopped having back pain within 3 days.' - Sarah K., software engineer
