v0.46.1

• Fixed: an ACF subtitle containing Markdown punctuation was parsed instead of
  read. A subtitle of A *literal* marker was emitted raw between the emphasis
  delimiters, so the reader's own asterisks took part in the formatting and the
  single italic line came out as three runs of emphasis. Subtitle text is now
  escaped the same way the article body is, so it reads back exactly as typed —
  asterisks, underscores, brackets, backslashes and a leading # included.
• Fixed: a link whose body is a non-breaking space (or another invisible
  character) is now named from its aria-label or title like any other link
  that renders nothing. Card and link-preview plugins fill an overlay link with
    rather than leaving it truly empty, and those links were still
  arriving as [](url "Name") — with the name in the tooltip and nothing tying
  it to the address.
• Changed: the documentation site is now built on every pull request instead of
  only after merging, so a broken page cannot reach the published site.
