+	Left alone, the variable and static versions of Inter will clash in font menus. 
+	See (https://github.com/google/fonts/pull/1908#issuecomment-575778671)
+
+	This script will update static-family names to include "Static" after the primary family name, to avoid this issue.
+
+	NOTE: this script is simple because "Inter" is such a short name. If a font has longer names, 
+	it should instead append an abbreviated suffix, such as "St" or "Stat"
