/* ===================================================================
   DTF Station Vietnam — blog (/blog and /vi/blog)

   Rides on assets/design.css: the cards are the design system's `.card`
   with a photograph in the media well, and the article body is the one
   place on the site with long-form prose, so it gets its own measure and
   rhythm here rather than borrowing a component that was not built for
   running text.

   Scoped to .gs like everything else.
