Red first (K3-19 c). SPEC SS 4.1 makes `description` RECOMMENDED -- "A single
sentence summarizing the concept" -- and sets no length limit anywhere, so
the limit is ours: the FIRST <p> of the FIRST direct-child
<sec sec-type="spec"> of a titled <sec>, whole. Measured on R761, 2 026 of
2 761 titled sections carry such a point.
8 of 11 red on 912b850: OutlineMark has no description, the plan carries
none, the loader validates none, and the door writes none. The 3 that pass
pin what must not move: the extracted text, a type that declares no spec
point getting no key, and a stated `--frontmatter description=...` replacing
the derived one (landed with b).
