/*
 * THE LISTBOX BODY — Base UI's `Combobox` supplies the keyboard model, the
 * highlight and the filtering; this sheet supplies the surface. Two washes, one
 * weight apart, so `[data-selected]` and `[data-highlighted]` stay tellable.
 *
 * The scroll lives on the list rather than on the root, so a search field and a
 * select-all band stay OUTSIDE it and a long list scrolls under both.
