/* =========================================================
   LOGIN — Acceso de usuario.
   Unificado al mismo lenguaje plano que downloads.css /
   register.css: sección sobre #000, sin imagen de fondo, sin
   overlay ni vidrio esmerilado. La tarjeta (.login-card) usa el
   mismo tratamiento que .register-card: fondo opaco, borde fino
   y acento superior dorado.

   El título (eyebrow + title-row con líneas doradas) mantiene el
   mismo lenguaje tipográfico que el resto del sitio (downloads,
   register).

   Los campos del formulario (.login-label, .login-input-group,
   .login-input, .login-check, .login-submit-btn) son EXCLUSIVOS
   de esta vista. La alerta (.alert.alert-danger) sigue siendo
   genérica y se mantiene sin cambios en style.min.css.

   Requiere las variables de :root definidas en style.min.css
   (--gold, --gold-light, --gold-dark, --brown, --gold-glow).
