/* CESCAC portal de vendedores v2 (Fase 4b): inicio de sesión y registro.
   Referencia de diseño: 21st.dev "Auth Switch" (appvibed01), la misma que usa el acceso del CRM (login.php): panel circular que se desliza
   entre "iniciar sesión" y "registrarse", con los colores y tipografías de CESCAC. Sin iconos de redes sociales (no hay acceso social).
   Escritorio (>870px): deslizamiento. Teléfono: una columna con pestañas. Los IDs y clases que usa el JS
   (.tab, .form-section, .success, .error, #refStatusCrm.si/.no/.verificando) se conservan. */
