   Article summary  (rendered by inc/tldr.php, above the first paragraph)

   Inverted panel: near-black with the brand green, dropped into a #fafafa article.
   The inversion is the point — it borrows the site's own dark/green identity so the
   summary reads as a deliberate part of the design rather than a generic tinted
   callout box, and it separates itself from the article without a border.

   Disclosure is a native <details>. The caret sits at the far right on its own
   baseline rule, so the closed state reads as one typographic line rather than a
   bulleted heading.
