// Fixture-driven tests for convert_deflists. Every fixture is exact-matched
// against its oracle in testdata/deflists/expected/. See
// testdata/deflists/reference/README.md for how each expected file was decided
// (cross-checked against Pandoc and Hugo/Goldmark).
//
// The fixture inputs are the definition-list examples from
// https://www.markdownlang.com/extended/definition-lists.html
//
// Provenance of each expected file:
//   01,02,08,09  Pandoc and Hugo agree; oracle = that agreed HTML.
//   06           Both agree it is NOT a deflist; convert_deflists passes the
//                markdown through unchanged, so expected = the raw input.
//   07           CommonMark's <4-space marker rule: we accept the 2-space colon
//                (Pandoc does; Hugo does not).
//   05           Block nesting is unsupported; our flatten happens to match
//                Pandoc's output exactly.
//   03,04        Block content in definitions is unsupported; expected captures
//                our current degraded behavior (a <dl> for the term/first line,
//                the rest falling through as markdown) as a regression guard.
