   XPLOROO · Authentication module
   auth.css — Shared styles for login.html and signup.html. A single
   `.auth-*` namespace so both pages stay visually identical and this file
   can't leak into any other page. Reuses the global `.field` / `.input` /
   `.select` / `.btn` design system from utilities.css — only the card
   shell, layout grid and small auth-specific bits live here.
   Load AFTER utilities.css.
