/* =========================================================================
   KAAYA GLOW — LOGIN PAGE, V2 ("LG" DESIGN SYSTEM)
   A self-contained layer for login.php's card only. Reuses sitewide tokens
   (--kaaya-*, --kg-*, .kg-container, .kg-eyebrow) for brand consistency.

   IMPORTANT: .kg-auth-card / .form-group / .register-link are shared with
   register.php (and .kg-auth-card with book-appointment.php too) — this
   file never touches those selectors. login.php's card below uses entirely
   new "lg-" markup/classes instead. .hero-banner above the card is shared
   sitewide and is also left untouched.
