/* ============================================================================
   auth.css — shared look for the unauthenticated / pre-app pages:
   login.html, first-login.html, reset-password.html.

   A centered white card (TIS color logo + "AgentDesk" rule) floating over a
   full-bleed photo: Adobe Stock #1489998918, Standard License (see
   login-bg.webp / login-bg.jpg, 2560px web copies).

   Both status-bar vocabularies are supported because the page scripts toggle
   different class names: login.js uses .status + .show, first-login.js /
   reset-password.js use .msg-bar + .visible. Same for the secondary action:
   .text-link (button) and .back-link (button or <a>).
