One build-less TSX panel that uses every component in the components catalog: form controls (Textarea, Checkbox, RadioGroup, Slider, Field), layout (Tabs, Collapsible, Toolbar, Grid, Box, tooltips), a paged and sortable Table, a lazily loaded Tree, Markdown, CodeView, a plugin Image, KeyValue, Callout and Skeleton. It needs Orca 1.4.248 or newer (Box is catalog 4).

orca plugin dev load .   # also writes .orca/types, the typings tsconfig.json extends
orca plugin test .       # runs src/panel.test.tsx in Node with orca/testing
orca plugin check .      # renders the panel once and reports errors with file:line

src/files.ts stands in for a data source: the Table asks for the next page with onLoadMore when the person scrolls near the end, and the Tree reads a folder's children on first expand.
