/**
 * The furniture every bench page is built from.
 *
 * One table renderer, not four. The published runs come in four shapes —
 * retrieval rows, code rows, the per-category sections, the LongMemEval tally —
 * and each was a table component of its own that differed only in which columns
 * it spelled. A column is `{ head, get }`; the shape it reads is the caller's
 * business, and the borders, the alignment, the tabular figures and the
 * horizontal scroll are settled once here.
 *
 * The index is built from the same pieces, so a reader arriving from it does
 * not land on a page that looks like a different site — and so the index holds
 * no style value of its own, which keeps its source free of every digit that is
 * not a figure read from the data.
 *
 * Every piece is a component on gui props. These pages are dark by design — a
 * black page in white type whatever the site's theme — so the inks are stated
 * against that ground rather than the theme's.
