/**
 * THE INDEX TYPES NO NUMBER.
 *
 * /benchmarks quotes results from pages that carry the whole table, and it is
 * where a figure is most tempting to type and least likely to be checked. It
 * carried a frontier grid ranked first on every benchmark it named, a
 * throughput twenty to ninety times the measurement, a Metal ratio and a
 * LongMemEval baseline that disagreed with the files beside them, and a spawn
 * time named for sandboxes it never measured. So every figure there is read
 * from INDEX in lib/bench-data, and this reads the index's source and fails on
 * any digit outside a comment. Style values count too: they live in the kit,
 * so that a digit in the index can only be a claim.
 *
 * And the figures come from one place. An import from anywhere but bench-data,
 * the registry and the kit is a second source, typed somewhere this does not
 * look. The registry is allowed because the index renders only its names and
 * prose, and that prose is held to the same rule below.
 *
 * This reads the source, not a render, so it runs without a server and fails on
 * the commit that types the number.
