/**
 * Chinese and Japanese inline annotations before measurement (#193, #194,
 * #195, #421): what the configuration makes of the spans the parser
 * marked, on every text the layout measures as a block.
 *
 * - `cjk.emphasis: 'dots'`: the Chinese and Japanese characters of `*…*`
 *   lose their italics and take emphasis dots; Latin letters in the same
 *   emphasis keep the italics.
 * - `cjk.emphasisMark`: what an emphasis mark leaves unset (`:dots[…]`
 *   without `style`, `*…*`) takes the configured or regional shape, fill
 *   and side (the sesame over the text in Japan).
 * - `cjk.bookTitleMark`: `'brackets'` adds the `cjk.bookTitleBrackets`
 *   (《》 and 〈〉 nested; 『』 and 「」 in Japan) around each `:book[…]`
 *   title as text the lines are broken with (spans flagged `inserted`,
 *   which take no character of the plain text); `'wavy'` keeps the
 *   title's run for the wavy line; `'none'` drops it.
 * - Ruby readings and warichu notes get their font (at their size, in the
 *   text's face unless `cjk.ruby.fontFamily` names one) and colour; a note
 *   gets the brackets `cjk.warichu` gives it unless it names its own. In
 *   Japan (and where `cjk.ruby` asks for them) readings also take their
 *   overhang and alignment rules, and a reading per character of a word
 *   becomes a jukugo ruby (#422).
 * - Kanbun marks (`:kunten[…]`, #430) get their font (`cjk.kunten.fontSize`
 *   in the text's face), colour and placement.
 *
 * Spans without any of these marks pass through untouched (the same
 * array), so text without them measures and caches as before.
