/* Figures for generated posts.
   A draft can carry a <figure class="post-figure"> block in its Markdown; the
   generator passes it through untouched and every post page links this file.
   Captions follow the house pattern set by From Gutenberg to AGI: a sentence
   that earns the image, then creator, date, holding institution, licence and a
   link to the source file. */
