 * Blog styles for dianajue.com
 *
 * Loaded AFTER css/resume.min.css and only on blog pages. The base template
 * sets every heading to 'Saira Extra Condensed', uppercase, with h1 at 6rem --
 * great for a one-page CV, unreadable for long-form prose. Everything below
 * scopes friendlier typography to the blog without touching the home page.
 *
 * Palette (inherited from resume.css):
 *   maroon  #af103b   maroon-dark #824027
 *   gray-800 #343a40  gray-700 #495057   gray-600 #868e96

/* Captions.

   Alt text is never displayed -- it exists for screen readers and for the
   case where the image fails to load. A caption you can actually see is an
   italic line placed DIRECTLY under the image, with no blank line between
   the two:

     ![Alt text, describing the image for screen readers](/img/blog/photo.jpg)
     *The caption everyone can see.*

   No blank line means kramdown keeps both in a single <p>, so the caption is
   the <em> immediately following the <img> -- which is what the selector
   below matches. A blank line would split them into two paragraphs and the
   line would render as ordinary italic body text instead.

   Deliberately plain Markdown: a Liquid {% include %} or a raw <figure>
   block would style the same way here but would not preview in Obsidian,
   where these posts are written. The `img + br + em` half of the selector
   covers kramdown's hard_wrap mode, in case it is ever switched on. */
