Endfield has two server groups, not three: Europe is served off the
Americas machine on a fixed UTC-5, so a European player's day rolls at
09:00 UTC. We were resetting it six hours early, at 03:00, which ticked
the wrong box every morning between those two instants.
Adds GameMeta.resetOffsets, a sparse per-region override, and threads an
optional `game` through every day-key function. Per region rather than
per game on purpose: a blanket offset would drag Asia — which does have
its own Endfield server — onto the Americas clock, moving day keys for
readers who never had the bug. A regression test pins Asia's output as
identical to before.
Day keys are localStorage keys, so this re-labels ticks logged between
03:00 and 09:00 UTC by European Endfield players, one day backward. No
tick is deleted and past days stay editable, but a streak can read as
broken for a day. That is the cost of correcting a wrong reset; leaving
it wrong is worse.
