+// #351 regression — DEGENERATE orderedList `start` normalization (DO-1).
+//
+// Only an INTEGER >= 2 is a valid explicit start. A degenerate start (0,
+// negative, fractional, non-number) MUST collapse to the default 1 on export:
+// emitting the raw value would produce an untokenizable marker (e.g. "-3.",
+// "2.5.") that `marked` cannot parse, causing the WHOLE orderedList (and its
+// listItems) to re-import as a PARAGRAPH — structural corruption. This test
+// pins that each degenerate start:
+// (1) exports to "1."/"2." markers (default numbering),
+// (2) re-imports as a VALID `orderedList` (not a paragraph) with `start`
+// defaulting, structure preserved,
+// (3) is byte-stable (md1 === md2).
+//
+// Mutation check: revert the converter guard to `Number(raw) || 1` and this
+// test goes RED (a fractional/negative start leaks into the marker).
+// ---------------------------------------------------------------------------
