   Every figure in this guide is marked up as <figure class="shot"> with a
   real caption. Until the PNG exists, the figure carries an extra
   "shot--todo" class and renders as a dashed box naming the file that should
   replace it. Swapping in the real image is a two-line edit — see
   SCREENSHOTS.md — and nothing about the surrounding page changes.
