/* Airlift Journal: article, index and hub pages (generated by generate-journal.mjs).
   ==============================================================================================
   Built from the "Article template" design reference (airlift-article-reference*.dc.html in the
   setup kit): values below are the reference's, on the site's own tokens. The light surface uses
   the /shop configurator's palette (#cf-shared-css in shop/index.html), including its rule that
   #0a8f6b is for FILLS only (ticks, icons, rules) and TEXT takes #087658, which clears WCAG AA
   4.5:1 on white and bone where #0a8f6b measured 3.7 to 4.1:1.

   Everything is scoped under .jr so nothing leaks into the shared header and footer. Motion is
   transform/opacity only; the reading progress bar has no transition at all.
