I have added a read-only React KPI Scorecard sample to the PnP SharePoint Framework webparts repository:

https://github.com/pnp/sp-dev-fx-webparts/pull/6478

The web part reads a configured SharePoint list and renders up to six KPI cards with:

Current value and target
Deterministic on-track, attention, at-risk, and unknown states
Trend from the latest two observations
Optional date filtering
Loading, empty, access-denied, not-found, throttling, and refresh states
Fluent UI components and keyboard-friendly status presentation

Local verification is complete: five Jest tests pass, TypeScript compiles, ESLint is clean, webpack builds, and the production .sppkg package validates.

Tenant validation requested

Could someone with a SharePoint Online tenant please try this with a representative KPI list and report:

Whether list and field configuration works as documented.
Whether number/date values map correctly from common SharePoint column types.
Whether threshold and trend states are understandable.
Whether the layout remains usable at narrow web-part widths.
A real tenant screenshot, if possible, for the PR gallery validation.

I do not have a suitable SharePoint Online tenant for producing an authentic screenshot, so I am intentionally asking the community rather than inventing one. Positive or negative findings are welcome; they will help make the sample more useful before merge.
