fix(rec): a fresh take starts its clock at zero, not at the last take's total

Two effects, wrong order: the ticking effect ran before the reset effect on a
new take, so its closure captured the PREVIOUS take's elapsed as its starting
point — the counter showed 0 for one second and then jumped back to thirty
minutes. Effects run in declaration order; the reset now comes first.
