Hold the time apart from the title on any font (#219)

The medium-to-regular step is a no-op on Atkinson Hyperlegible, JetBrains
Mono and imported fonts, which ship no medium face — so the title takes
full ink against the time's 0.8 instead, and the four title sites share
the constant.

Also: the drag copy carries the time its source chip had rather than
deriving one with continuesLeft hardcoded false; the month grid takes
its zone from the state; times are formatted once per row and the chip
width measured once per grid; the chip geometry lives in one file; and
a screen reader hears the time whether or not the chip is wide enough
to draw it.
