/* ═══════════════════════════════════════════════════════
   NCAT Certificate System — Auth Pages Stylesheet (v2)
   dash_settings/css/auth.css
   Covers: login.php, cpassword.php, cpasswordf_reset.php

   Fixes from design review:
   - Font sizes switched from rem to px. The reference template's
     rem values were computed against ITS OWN root font-size; on
     this app's pages the inherited root font-size is different,
     so the same rem numbers rendered visibly smaller. Px values
     render the same everywhere regardless of what else is loaded
     on the page.
   - The top navbar is `navbar-fixed-top` (position:fixed) and
     nothing in the existing theme (startmin.css) compensates for
     that with body padding, so the auth card was sitting flush
     against/under the navbar. Fixed with body.auth-page padding-top.
   - New split layout: a sky-blue aircraft visual panel alongside
     the form, instead of a single narrow card.
