// Christmas Cookies
// It's December 1st! That means it's almost time for the big day! Santa has a preparation regimen that involves, of course, eating lots of delicious cookies.
// Santa's elves have provided Santa an API whereby Santa can submit his favorite cookie flavors. This year his favorites are:
//     ginger-bread
//     chocolate-chip
// But the elves have some kind of fancy code-gen build step (built in Rust, of course), so all Santa needs to do is update the SantasFavoriteCookies type to accept either of his favorite cookies.
// Can you help?

type SantasFavoriteCookies = 'ginger-bread' | 'chocolate-chip';
