/**
 * Insert a word joiner (U+2060) immediately before each unspaced em or en
 * dash that has preceding content, preventing the dash from appearing as the
 * first glyph on a wrapped line. The em dash (U+2014) is Unicode line-break
 * class B2, which permits a break on either side; the en dash (U+2013) is
 * class BA (break after). The word joiner glues either dash to the preceding
 * word so it cannot start a wrapped line. Does not insert before line-leading
 * dashes (preceded by whitespace or start-of-string) or dashes already glued
 * with a word joiner — including British-style spaced en dashes ("word – word"),
 * which are already protected by the surrounding spaces.
 *
 * **Trade-off:** the inserted U+2060 is invisible but present in the DOM, so
 * browser Ctrl+F / find-in-page will not match a query like `plan—result`
 * against the rendered `plan⁠—result`. This is the same trade-off made by
 * `nbspTransform` (U+00A0 breaks `Fig. 1` searches). Apply only in rendered
 * HTML; do not write into Markdown source.
