/* Sift's site. The palette and the font come from /design/tokens.css, the sites' look (header, buttons, labels, cells,
   questions, footer, the privacy page) from /design/site.css, linked before this file (the monorepo's shared design,
   ../../../design/README.md). This file adds the site's own idea: the demo in the hero, a made-up page filtered by one
   of three rules chosen with radio buttons (no scripts). Choosing a rule outlines each item in turn, as the extension
   does while it asks about it, then fades what the rule sends away. The page is someone else's, so it keeps a page's
   own colours (white, near-black ink) by day and by night. Nothing loads from another host. */
