   login.css
   Loaded ONLY by login.php (body.login-page). Mirrors the dashboard's own
   visual language - the same soft slate background, the same violet /
   indigo / teal accent trio used by the three module cards, the same
   pill buttons and rounded-card conventions as the rest of the app -
   so the sign-in screen reads as the front door of the same product,
   not a bolted-on separate design.
