/* Lowbird — design system condiviso (web app, backoffice, box dell'estensione, Mini App).
   Carta fredda e inchiostro; verde "affare" e rosso "caro" hanno un significato (prezzo sotto o sopra
   la media), non sono decorazione. Archivo per tutto: condensato e pesante per i prezzi, come un
   cartellino. L'elemento distintivo è la barra del prezzo (.prange). */
