Remarkably simple - slightly odd, but I can see how it gets the desired effect.

An earlier version of this feature is already present on alpha-v9 from a prior meeting. Edits made to this PR since then are not yet on alpha-v9; they will land at the next propagation. If you need them on alpha-v9 sooner, please open a separate PR targeting alpha-v9.
Thanks!
