/* Hides the page until the gate in js/gate.js decides whether there is a
   session. Its own file, loaded only by index.html: the login and reset pages
   must NOT start hidden, and it is not in style.css for exactly that reason.

   It was an inline <style> until the app got a real CSP - see public/_headers.
   A stylesheet link in <head> blocks paint the same way the inline block did,
   so nothing about the behaviour changed. */
