/* Guides and the blog: calm, long-form reading pages in the site's paper-and-felt look. Mobile first.
   Every image has its size set, so nothing shifts as tiles load; tiles below the fold load lazily.
   Felt is flat (design.md: no gradients); gold is the Score's gold, used sparingly for emphasis.
   #quick-answer and .article-body h2 are speakable selectors in the page's JSON-LD: keep them. */
