AD devs: before updating the sync version to 10, please make sure
the new timezone code has been ported over. The core change to the
scheduler is in _updateCutoff():
b198ba8073/pylib/anki/schedv2.py (L1357)
with the following supporting Python functions:
b198ba8073/pylib/anki/schedv2.py (L1410)
_timing_today() is calculated in Rust (lines up to 92, the rest are
tests):
b198ba8073/rslib/src/sched/cutoff.rs (L20)
The change went through a few iterations before stabilising, so it's
probably easier to refer to the above code than the patches that got
us to that point.
Forces the Fusion theme when running night mode, so we don't need
to work around platform themes that don't respond to the defined
palette.
Feedback/suggestions on the chosen colours welcome - _vars.scss is the
file to change if you want to experiment with adjustments.
