The rules that are expensive to rediscover: integer-only arithmetic and why
(Python and Dart round differently), the count clamp and why a duplicate slot
hour is worse than it looks, the last+2h cutoff and its midnight clamp, and
the required-argument decision in _slots.py / slot.dart.
Split into docs/meal-schedule.md rather than inlined -- CLAUDE.md hit 276
lines against the 250 cap, the same split the Flutter rules already use.
