+Subject: [PATCH] Fix sassc requirement for tarball builds
+
+The meson build checks for base.css to determine if pre-generated CSS
+is available, but the tarball ships gtk.css instead. This causes sassc
+to be required even for tarball builds where the compiled stylesheet
+is already present. Fix the check to look for gtk.css.
