608 B of flash, 7.6 % of the image, and it is not available: this board runs
continuously and an uptime that restarts every 49.7 days is not acceptable,
which is what a 32-bit millisecond counter wraps at.
The tick split goes with it. It only ever made sense beside the narrowing, and
on its own it costs 66 B to buy about 0.4 % of a CPU nothing here is competing
for.
Both are recorded rather than deleted, and that is the point of the change: the
numbers are real and re-measurable, so someone will find 608 B again and read
it as an opportunity. What they need with it is the reason it was refused.
Docs only; five tests green.
