Inizia da docs/products/buttons.mdx e scss/product/components/_buttons.scss, quindi riproduci il TypeError segnalato durante la build della documentazione. Rintraccia l’errore di slice segnalato fino all’esempio del toggle arrotondato o al relativo stile e considera il lavoro completato quando l’esempio viene compilato senza errori e visualizza il toggle arrotondato previsto.
