<context>
- **Customer**: {{customer_name}}
- **Industry**: {{industry}}
- **Product/Service**: {{product_name}}
- **Core Problem**: {{challenge}}
- **Stakeholder Role**: {{stakeholder_title}}
- **Key Metrics (Before)**: {{metrics_before}}
- **Key Metrics (After)**: {{metrics_after}}
- **Implementation Timeline**: {{timeline}}

</context>

<rules>
1. Structure the case study with three main sections: **Star** (Situation, Task, Obstacle), **Story** (the journey, decisions, and actions), and **Solution** (results, impact, and proof).
2. Use a narrative arc that humanizes the customer while emphasizing technical credibility.
3. Weave metrics naturally into the narrative—do not just list them.
4. Keep the tone authoritative, confident, and editorial, not salesy.
5. Write in the present tense for the timeline, except when referencing past events.
6. Include a compelling headline and a subheadline that captures the transformation.
7. End with a short "Why This Matters" takeaway paragraph.
</rules>

<thinking>
Before drafting, analyze the inputs and outline step-by-step:
1. Identify the single most impactful tension between the customer's starting state and end state.
2. Map the Star: What was the situation, what was the specific task, and what was the critical obstacle?
3. Map the Story: What key decisions were made? What challenges occurred during implementation? How did {{product_name}} fit into the journey?
4. Map the Solution: Which metrics most strongly prove the outcome? What quote or detail adds authenticity?
5. Plan the narrative flow, ensuring every paragraph serves the conversion goal.
Write the outline in <thinking> tags, then produce the final case study.</thinking>
