## Style reference

### Skin

`@xihan-ui/styles/tree-select.css` is written against `[data-scope="tree-select"][data-part="root"]` part selectors; the published build uses the mount class `.xh-scope-tree-select` in place of data-scope (same specificity) and sits in the `xihan.components` layer. Put overrides in `xihan.overrides`; the part selectors work as usual.

### Data attributes

Produced by `connect`; valueless attributes are omitted while their condition does not hold.
