// Port of web/kit/AutoTable.tsx.
//
// NOTE: AutoTable.tsx is ~4200 LOC and heavily coupled to the browser. This is a
// faithful, COMPILING *core* — the column model, the header/body/pagination
// render shell, and the Tailwind styling — not a behavioral clone. The following
// substantial features of the TSX are INTENTIONALLY OUT OF SCOPE here because
// they depend on DOM measurement, refs, timers, portals, or floating-ui, none of
// which exist in the neutral vdom runtime:
//
//   - Virtual scrolling / windowed row rendering (rows are rendered eagerly).
//   - Column drag-to-reorder and drag-to-resize (getBoundingClientRect, refs,
//     mousemove tracking) — replaced by a static per-column WidthClass.
//   - Computed/pinned table sizing (pinnedTableWidth measurement) — replaced by
//     table-fixed + static WidthClass.
//   - Runtime-editable calculated columns and footer summary rows, the whole
//     Excel-style formula engine (tokenize/compile/highlight), and their popover
//     editors (Popover/Menu/floating-ui).
//   - CSV and PDF export (pdf-lib / pdfjs-dist), and the export/customize popover.
//   - Remote data fetching (authFetch), remoteFiltering, refreshSignal.
//   - Search/filter toolbar, quick-date presets, column-visibility toggles, the
//     search-aside card, and localStorage persistence of order/width/columns.
//   - Accordion expand/collapse rows and row-highlight auto-paging.
//   - Client-side sorting/filtering/pagination logic (compareRowsGeneric,
//     processDataLocally): sort state and pagination are surfaced here as plain
//     value props + callbacks; the caller owns the actual sort/page computation.
//
// What IS ported: the AutoTableColumn model (header text, alignment, width class,
// sortable + a cell render func), the AutoTable render shell (sticky header,
// body rows, loading skeletons, error/empty states, display-only pagination),
// the verbatim Tailwind class constants/maps, and sort/pagination as props +
// callbacks. Reactive accessors collapse to plain values per the port guide.
