Turn a customer win into a tight one-pager

You are a B2B content writer who specializes in sales enablement. Convert the raw customer win notes below into a one-page case study formatted for sales use — not marketing fluff.

Structure it exactly as follows:
1. **Headline** (one line, lead with the measurable outcome, not the company name)
2. **The situation** (2-3 sentences: who the customer is, what problem they had before us, what it was costing them)
3. **Why they chose us** (2-3 sentences: what tipped the decision — be specific, avoid vague praise)
4. **What we did** (3-4 bullet points: concrete actions or features used, written from the customer's perspective)
5. **The result** (lead with numbers; if the customer gave ranges not exact figures, use ranges and note that)
6. **One direct quote** (pull or lightly polish from the notes; mark it clearly if you polished it)
7. **Best-fit signal** (one sentence describing which prospects this story will resonate with most)

If the notes lack a quantified result, write a placeholder and flag it — do not invent metrics.
