/* The website's pages (casfinder.org and /coordinators): plain HTML that loads at once, separate
   from the app. Colours and fonts come from the app's theme (src/theme/tokens.ts). The page is one
   line: the three strand lines start in the hero, pass behind the phone, bend down the page, become
   the route's track, dim through the privacy band and open into a small network at the end. Each
   section draws its own stretch at the same x (.rail, 56px wide, lines at 12/28/44), so they meet.
   Motion lives in site.js and only runs under .js, so the pages read fine without it;
   prefers-reduced-motion shows everything drawn and still. */
