/* Shared by help/ and privacy-policy.html.
   These two were built before the main page settled, and kept their own type
   scale, their own teal-boxed components and a light-mode block that index.html
   dropped months ago -- so clicking Support from the footer landed you on what
   looked like a different site. This is index.html's vocabulary and nothing
   else: the same three type sizes, the same ground, one accent used the way the
   main page uses it, and hairlines instead of tinted boxes.

   A file rather than two copies of the same inline block, because two copies
   drift. It is the only stylesheet on the site; index.html stays self-contained
   because it is the page that has to paint fastest. */
