@pnicolli @deodorhunter ho impostato di default in storybook il parametro excludeDecorators: true
così non dobbiamo impostarlo ogni volta che usiamo un decorator.
In più ho messo a fattor comune il decorator w-100 che ti permette di espandere il contenitore della storia al 100%.
Si usa come un semplice parametro fra i parameters della Story (o nei meta se vi è piu comodo, a seconda delle necessità).
