### Prompt – Landing Page Copy & A/B Test Generator
**Context**
- **Product name**: {{product_name}}
- **One‑sentence value proposition**: {{value_prop}}
- **Target persona** (age, role, pain point): {{persona}}
- **Primary benefit**: {{primary_benefit}}
- **Secondary benefit**: {{secondary_benefit}}
- **Desired CTA text**: {{cta}}
- **Emotional trigger for Variant A** (e.g., urgency, scarcity): {{trigger_a}}
- **Emotional trigger for Variant B** (e.g., trust, authority): {{trigger_b}}

**Task**
1. Act as a senior conversion copywriter.
2. For **Variant A** and **Variant B**, produce:
   - **Headline** (max 12 words)
   - **Sub‑headline** (max 20 words)
   - **Three benefit bullets** (each ≤ 15 words)
   - **CTA button copy**
3. Output both variants in **Markdown** side‑by‑side, using headings `## Variant A` and `## Variant B`.
4. After the copy, include a **Testing Metrics Table** with suggested KPI (CTR, conversion rate) and measurement method.

**Quality Bar**
- Copy must be **clear, benefit‑focused, and free of jargon**.
- Each variant must reflect its assigned emotional trigger.
- Use active voice and power verbs.
- No more than 300 characters total per variant.

**Constraints**
- Do not repeat exact phrasing between variants.
- Keep brand voice neutral; only the emotional trigger should differ.
- Return **only** the markdown content.
