+// A media type (also known as MIME type and content type) is a two-part identifier for
+// file formats and format contents transmitted on the Internet.
+// For Hugo's use case, we use the top-level type name / subtype name + suffix.
+// One example would be image/jpeg+jpg
+// If suffix is not provided, the sub type will be used.
+// See // https://en.wikipedia.org/wiki/Media_type
