/* About (templates/about.html), on top of auth.css: who makes the app. A hero with the facts at a glance beside it, the

   and a last word. Drawn only with the look's tokens (looks.css); the studio's tile keeps its own slate, as a logo
   does. Sections rise into view as they're scrolled to (about.js adds .motion unless motion is off). */
