/* The xwaivers landing page. Separate from style.css and from landing.css on
   purpose: the app's stylesheet stays small, and each product's front page can
   be redesigned without touching the other one or a signing page.

   No outside fonts or images: the Content-Security-Policy allows only this site,
   and this page deliberately uses no vendored font either, so it costs nothing to
   load. Where PDF Signer's page is a writing desk in warm paper, this one is a
   front-desk tool: cool, flat, plain type, one orange accent for the things that
   are done. */
