/**
 * Spec-derived companion to `MARKDOWN_CORPUS` (same contract, same
 * two-engine gate): example *inputs* from the pinned CommonMark and GFM
 * spec sources listed in `scripts/generate-markdown-spec-corpus.ts`,
 * mechanically filtered to the entries both editor engines already handle
 * identically. Fixture names carry the source spec's own example number,
 * so `commonmark 0.31.2 ex 341 (Code spans)` can be looked up upstream.
 *
 * - Fixtures without `canonical` round-trip byte-identically in BOTH
 *   engines.
 * - Fixtures with `canonical` normalize to the same stable bytes in both
 *   engines, and the canonical form parses to a document equal to the
 *   input's parse — normalizations that lose content (dropped hrefs,
 *   truncated targets) are filtered out by the generator and must never be
 *   added here by hand.
 *
 * A failure means an engine's round trip drifted (or the engines diverged)
 * — fix the engine, or, for a deliberate serializer change, rerun the
 * generator and review its diff.
