/* Shared by the four standing pages -- privacy, terms, about, contact.

   These are plain HTML in public/, not views inside the app, on purpose. They
   need real URLs that a crawler can fetch and read without running any
   JavaScript: a privacy policy that only exists once React has booted is a
   privacy policy an AdSense reviewer cannot find. Firebase serves files that
   exist in public/ before it considers the single-page rewrite, which is what
   makes /privacy.html a real page rather than the app's shell. */
