+spec: https://drafts.fxtf.org/css-masking-1/#clipping-paths
+# https://caniuse.com/css-clip-path is not linked here because the browser
+# versions are very different, mostly due to lack of support for url() for
+# external SVGs being treated as partial support. That is not essential to
+# using the feature, and not even mentioned on MDN.
+# TODO: align with caniuse and link it here.
