+ *
+ * Each item passed to `populate` is `{ label, render?, onPick }`:
+ *   - label: string used for the data-label search filter.
+ *   - render: optional () => Element factory. If omitted a bare hbox
+ *     with a <label> is created.
+ *   - onPick: callback invoked when the item is clicked or activated
+ *     via Enter on the keyboard.
+ *
+ * The driver handles:
+ *   - filtering by lowercased substring match against data-label;
+ *   - arrow-key / Tab navigation with [selected="true"] highlight;
+ *   - Enter to activate the highlighted item;
+ *   - autofocus of the search input on popupshown;
