/* ===== Email-verification notice after registering ==========================
   Rendered by views/auth/login.php only in the request right after a
   successful registration. It is visible from the first paint — no script
   opens it — because the sign-in page is the last place a new user should be
   left guessing why their password is refused. */

/* Its own palette on purpose. The page's --login-* variables are filled from
   the site theme, where --login-primary-dark is the NAV BACKGROUND — light on
   this site — which left the heading and the email address almost invisible.
   A notice that has to be read cannot depend on a colour an editor may
   lighten, so these are fixed, and each pairing is checked for contrast. */
