 ### Added
 
 | Web component API | Notes |
 |---|---|
-| `data-state="on\|off"` on slotted children | Show different label text per state; children hidden/shown automatically |
 | External `<label>` support | FACE element works with native `<label for="id">` or nesting in `<label>` |
 | Form association | Submits `"on"` when checked, omitted when unchecked (matches native checkbox) |
+| Form reset | Reverts to initial `checked` value on form reset |
