/**
 * Deterministic benchmark corpora.
 *
 * `zipkit bench` with no file compares codecs on these built-in datasets, so
 * ratio/timing comparisons across versions or PRs are apple-to-apple instead of
 * depending on whatever file a user happened to pass. Everything is generated
 * from a fixed seed (no `Math.random`, no bundled fixtures bloating the
 * package), so the same input bytes are reproduced on every machine and run.
