/* The community (paavya.com/community/), laid out like a product community:
   a sidebar of places at the left, the newest update leading the middle,
   and a welcome, the feeds and "Start here" at the right. Loaded only by
   community/ pages (tools/build-site.mjs), after docs.css, whose screenshot
   frame (.shot) and pager it reuses. Every color is one of site.css's
   tokens, so light and dark follow the site (D-574). */
