-- A readable spelling tried ahead of a general one — a CommonMark block, the image, the pipe

-  before it can give way — the list, whose thematic-break first line and blank lines exist only
-  spelled — hands that one walk to the general form instead: giving way after the walk walks

 - Nothing recurses unbounded: the guards walk iteratively, and blocks, marks and JSON values — an
   attribute's and a carried node's alike — are all held to 500 levels, so a deep document is a
   `Result` rather than the stack overflow that waits near 2000. A level is one block-list
