/**
 * Headless data view: a sort / search / paginate state machine ported from the
 * maildrill `useDataView` hook. Wires search input, sortable headers and
 * pagination controls, emits `dataview:change` with the full state, and — when
 * `[data-c42-dataview-row]` elements are present — also filters, reorders and
 * paginates them directly in the DOM. Server-driven consumers omit the rows and
 * react to the change event instead.
 *
 * Markup:
 * ```html
 * <div data-c42-dataview>
 *   <input data-c42-dataview-search />
 *   <button data-c42-dataview-sort-field="name">Name</button>
 *   <div data-c42-dataview-rows>
 *     <div data-c42-dataview-row data-search="alice" data-field-name="alice"></div>
 *   </div>
 *   <button data-c42-dataview-prev>Prev</button>
 *   <span data-c42-dataview-page></span> / <span data-c42-dataview-pages></span>
 *   <button data-c42-dataview-next>Next</button>
 *   <span data-c42-dataview-info></span>
 * </div>
 * ```
