 * Excel-style **set filter**: a per-column checklist of the column's distinct
 * values. Unchecking values hides their rows. Pure UI on top of the grid's
 * public filter API — it builds a value-membership {@link FilterOperation} and
 * applies it via `grid.filter()` / `grid.clearFilter()`, so it needs no core
 * change and composes with the grid's other filters.
 *
 * Mount it (typically in a header popover) and set its `grid` + `column`
 * properties. Toggling an option applies the filter live.
 *
 * @element apex-grid-set-filter
 *
 * @csspart set-filter - The panel container.
 * @csspart search - The search input.
 * @csspart select-all - The "(Select all)" row.
 * @csspart list - The scrollable options list.
 * @csspart option - A single value row.
 * @csspart option-label - The `<label>` wrapping an option's checkbox + text.
 * @csspart checkbox - An option's checkbox.
 * @csspart label - An option's label.
 * @csspart actions - The footer button row.
 * @csspart clear - The "Clear filter" button.
