M0 said the big-readout typography would be settled once there was a
stopwatch to settle it against. `ClockulaTypography` now puts `tnum` on the
display, headline and title roles, which is every role a counting number
uses, and `ClockulaReadoutDefaults` names the three sizes the readouts share.
Digits stop changing width as they change, so the timer row, the setup panel
and the live pill stop twitching too — none of them needed a call-site
change to get it.
