/* ===========================================================
   CSIR-FIRST (Round 4) — Auth Pages Theme
   Shared by: login.php, forgot_password.php, reset_password.php,
   register.php

   Reuses the same design tokens defined in index.php so all
   pages of the portal look and feel like one product:
     --navy-950 / --navy-800   instrument-panel backgrounds
     --brass-500 / --brass-200 accent (seals, active states)
     --paper-100 / --paper-000 page / card surfaces
     --ink-900 / --ink-600     text
     --teal-700                interactive accent / focus
     --rule                    hairline dividers

   Loading this file once here avoids re-declaring the same
   tokens and rules inline on every auth page.
