## Thumbnail Screenshot Logic

HENGSHI SENSE has a built-in screenshot tool. The thumbnail is first captured at the default resolution of 1280 × 904, then scaled according to the thumbnail sizing rules.

## Thumbnail API Endpoint

Thumbnails are obtained via the API: `/api/apps/{appId}/dashboards/{dashboardId}/thumbnail`
