/**
 * Virtualized body of DataTable — renders 10K+ rows over @tanstack/react-virtual
 * (blueprint M6, ADR D1/D2 + review fix F-dom-1). Semantic `<table>` preserved
 * with the SPACER-ROW technique: two fixed-height spacer `<tr>`s grow the
 * table's real layout box to the full dataset height, so the sticky `<thead>`
 * keeps its containing block for the whole scroll and the last row stays
 * reachable — per-row transforms (the official example's pattern) do NOT grow
 * the layout box and un-stick the header after ~one window.
 *
 * Limitations (documented contract — mutually exclusive at the type level):
 * no pagination, no expandable rows (fixed row heights are required by
 * estimateSize). Cell content must fit `rowHeight` (cells are clipped with
 * reduced padding; keep rowHeight >= ~32px). A row-action dropdown unmounts
 * when its row leaves the overscan window.
