Generally assume that clock values always increase to simplify reasoning
everywhere clock values are used. Then enforce that assumption.
Clock values don't really, truly always go up because page reloads &
multiple devices, but since I'm not currently planning to spend the
effort that would be required to perfectly handle this in all cases,
making it happen in fewer cases is a win (rather than just making bugs
I want to fix harder to reproduce).
