+// Initialization partial
+//
+// To make it easier to use all variables and mixins in any Sass file in this
+// project, each .scss file has a `@import 'init';` declaration. The _init.scss
+// file is in charge of importing all the other partials needed for the
+// project.
+//
+// The initialization partial is organized in this way:
+// - First we set any shared Sass variables.
+// - Next we import Sass modules.
+// - Last we define our custom mixins for this project.
+//

+
+// The following Sass functions/mixins are required to generate some variables'
+// values, so we load them first.

+// 3rd party libraries
