   Gramática de la referencia que eligió Alex (kivra.se): panel de color
   profundo con esquinas muy redondeadas en cabecera y pie, botones píldora,
   tarjetas blancas con zona ilustrada en pastel, acordeón en crema y un
   modal blanco flotante. La paleta es la de la app —familia teal—, no la de
   la referencia: la estructura se toma prestada, el color no.
