@font-face font-variation-settings

Drag the sliders. The preview loads Recursive (a real variable font) via an @font-face rule whose font-variation-settings descriptor is rewritten live. With v140 the descriptor in the @font-face is the default — no need to repeat font-variation-settings on every usage.
