+Subject: [PATCH] build: Fix detection for pre-compiled css files
+
+The default theme changed from Adwaita to Default and this tripped up
+the logic to detect if the tarball builds contain pre-built css files or
+not. Fix this by looking at pre-compiled css files in themes/Default/
+instead of themes/Adwaita/.
