/**
 * Speculatively closes inline markup that the stream has not finished writing.
 *
 * Markdown is only meaningful once a construct is closed, so a document caught
 * mid-token renders its own syntax: `**bold` shows the asterisks, `` `code ``
 * shows the backtick, `[text](htt` shows the brackets. Every one of those
 * resolves a few tokens later, which makes the reply flicker between prose and
 * punctuation for the whole of its arrival.
 *
 * The fix is to close the open construct for the parser and let the real
 * closer, when it lands, simply match. Text never changes — only the styling
 * arrives slightly early, which is invisible, where the punctuation was not.
 *
 * Only the *end* of the document is speculative. An unterminated run in the
 * middle is a deliberate literal (`2 * 3 * 4`), and rewriting it would corrupt
 * what the author actually wrote.

 *
 * Synthesising the delimiter row lets the header render as a header
 * immediately and the body rows arrive underneath it. Streaming only: a
