+// Dev notes
+//
+// Background information on nomenclature and architecture decisions here.
+//
+// - Bootstrap functions, variables, and mixins are included for easy reuse.
+//   Doing so gives us access to the same core utilities provided by Bootstrap.
+//   For example, consistent media queries through those mixins.
+//
+// - Bootstrap's **docs variables** are prefixed with `$bd-`.
+//   These custom colors avoid collision with the components Bootstrap provides.
+//
+// - Classes are prefixed with `.bd-`.
+//   These classes indicate custom-built or modified components for the design
+//   and layout of the Bootstrap docs. They are not included in our builds.
