+// Cooking up additional types:
+//
+// The Sass for each hamburger type should be nested
+// inside an @if directive to check whether or not
+// it exists in $hamburger-types so only the CSS for
+// included types are generated.
+//
+// e.g. hamburgers/types/_new-type.scss
+//
+// @if index($hamburger-types, new-type) {
+//   .hamburger--new-type {
+//     ...
+//   }
+// }
