/* pp-story.css — the fast-facts strip and the slide deck it opens.

   A place page is a travel page and was a poor place to LEARN about the
   place. This is the educational layer: a row of fact tiles under the hero,
   and a deck of eight to ten slides a reader scrubs through, one idea a
   slide, every slide naming the Wikipedia article and the date it was read.

   Shared by country and city pages. pp-story.js drives it; the markup is
   baked into the page by tools/lib-static.mjs so a crawler reads the slides
   without running anything. */
