/* «Degradado» (RF-DIS-001): el dispositivo comunica, pero informa una falla
   funcional. Lleva color propio y no el de `alert` porque el criterio exige
   presentar los tres estados de forma distinguible, y dos naranjas no lo son.
   El color nunca va solo: cada insignia lleva su etiqueta textual, que es lo
   que RNF-USA-002 y WCAG 2.1 AA piden para no depender del color. */
