For the love of all that is holy, can you all please start using `<a>` for navigation and `<button>` for actions, not the other way around?

Please don't make me turn this into a blog post.

"L’asciugamano è forse l’oggetto più utile che un autostoppista galattico possa avere. Ve lo potete avvolgere intorno perché vi tenga caldo quando vi apprestate ad attraversare i freddi satelliti di Jaglan Beta; potete sdraiarvici sopra quando vi trovate sulle spiagge dalla brillante sabbia di marmo di Santraginus V a inalare gli inebrianti vapori del suo mare; ci potete dormire sotto sul mondo deserto di Kakrafoon, con le sue stelle che splendono rossastre; infine, potete usare il vostro asciugamano per fare segnalazioni in caso di emergenza e, se è ancora abbastanza pulito, per asciugarvi, naturalmente.”

Buon Towel Day a tutti!
Happy #TowelDay and #dontPanic ❤️
