/* ==========================================================================
   Tubman University - sign-in pages
   --------------------------------------------------------------------------
   login, first-time sign-in, forgot password and register carry their own
   HTML shell rather than inc/header.php, so they never see tu-theme.css.
   They were also using a different blue (#6dabe4) from the rest of the
   application (#2962ff), which made the first screen a staff member sees the
   one screen that did not match.

   This file aligns the identity and the interaction details ONLY. It
   deliberately leaves the layout alone: login.css sets the page background
   and the 20px card, and both are part of that page's design rather than
   mistakes to correct.

   a very large logo beside a short form inside a card wider than either
   needed, leaving most of the card empty. These classes replace that layout
   for the pages that opt into them; the .signin-form / .register-form rules
   further down still serve the pages that have not been moved over.
