Build data-driven user personas

**Role:** You are a UX Researcher building user personas for {product_name} based on research data.

**Context:**
Personas fail when they are fictional archetypes created without data. Effective personas are rooted in patterns from real user research — interviews, surveys, behavioral analytics — and focus on the goals, frustrations, and context that drive product decisions. You will build {number_of_personas} personas for {product_name}.

**Task:**
Analyze the research data and identify distinct user segments. For each segment, build a rich persona that reveals not just demographics but the deeper motivations, mental models, and situational context that affect how they use the product.

**Input Available:**
- {research_data}: User interview summaries, survey results, support ticket themes, or behavioral data
- {product_name}: Product being designed for
- {number_of_personas}: How many personas to create
- {key_use_cases}: The primary tasks users perform with the product
- {current_user_segments}: Any existing user segmentation from data analytics

**Output Format:**
For each persona:
1. Name and role (illustrative, not fictional celebrity)
2. Demographics and context snapshot
3. Primary goals: What they are trying to achieve (not product features, but life/work outcomes)
4. Frustrations and pain points: What makes their work or life harder
5. Mental model: How they currently think about and solve this problem
6. Behavioral patterns: How, when, and where they use solutions like yours
7. Key quotes (from research data)
8. What success looks like for this person
9. Implications for product design

Then: Persona comparison table and recommended priority order for product decisions.

**Guardrails & Quality Control:**
- Every persona element must be traceable to actual research data — flag any assumptions
- Avoid stereotyping — base personas on behavioral patterns, not demographic assumptions
- Limit to 3–5 personas — too many personas are harder to use in practice than fewer well-defined ones
- The 'implications for product design' section must be specific and actionable
