KPI dashboard specTemplateLow risk

Write a dashboard spec for {{team}} who need to answer: {{decisions}}.

For each metric (aim for 5–8):
- Name and one-sentence definition.
- Exact formula and data source.
- Grain (daily/weekly), filters and segments.
- Target or healthy range.
- Chart type and why.

Also include: metrics we deliberately left out and why, and a note on how often data refreshes.
