/* ============================================================
   Coffee Inventory · Acceso (login + recuperar contraseña)
   Estilo "Porcelana": fondo hueso con grano, una tarjeta blanca con
   sombras en capas y borde degradado, ícono de app oscuro, campos con
   etiqueta arriba y botón negro con relieve. Tipografía Geist.
   Maqueta de referencia: acceso/templates/login/premium/premium-2-porcelana.html

   Clases que controla el JS y NO se renombran:
     acceso/src/js/index.js     -> .login-error.show, .is-invalid, .loading,
                                   .caps.show, #btnEye, #rememberedUser,
                                   #forgetUserBtn
     acceso/src/js/recuperar.js -> .paso.on, .hide, .aviso-ok, .aviso-error
     src/js/plugins.js          -> span.text-danger(.hide) dentro del .field

   Las reglas de botones van con dos clases (.login-card .btn-continue): el
   preflight de Tailwind (CDN) pisa con [type=submit] a una sola clase.
