Review Comment:
**Suggestion:** Each geographic feature performs a linear search through all
query rows before applying conditional formatting. This changes rendering to
O(features × rows), while `colorMap` already provides an O(1) lookup; large
regional maps can therefore incur substantial rendering and interaction stalls.
Build a country-to-row or country-to-metric map once before defining `colorFn`.

```mdx
- ⚠️ Large regional maps perform quadratic color lookups.
- ⚠️ Initial rendering and interactions may stall.
- ⚠️ Conditional formatting redraws repeat the same searches.
