  Pautas:
    - [SRP]  Estilos exclusivos de la vista de login (estructura, formulario y visual).
    - [KEEP] No se modifican colores, tamaños, ni comportamiento visual/original.
    - [DRY]  Variables CSS en :root y organización por secciones con comentarios.
    - [A11Y] Mantiene focos/contrastes definidos por el diseño existente.
