   xw-  the made-up Spanish blog the learner is "reading"
   x-   the extension's own UI (tooltip, card form, toast), same look and

   xa-  a copy of the article page (templates/article.html)

   The stage is drawn at a fixed 960 x 640 and scaled by
   static/js/extension-page.js, which also moves a virtual camera over it.
