/* ==========================================================================
   Auth pages (login, register, forgot, reset, messages), blue-green tint.
   Loaded only on those pages. Tokens, the --th-* theme variables, the
   .hud-pane family and the xp- dialog kit (fields, primary button, error row)
   come from site.css (do not redefine them here).

   Each page is a compact pane ("login.exe", "register.exe", ...). The pane is
   the window: inside it the h1 is a wide light heading over a hairline, then
   the form, then the links as outlined buttons. Nothing else sits on the page.
