-- Sādhana reminder support.
--
-- timezone: the user's IANA zone (e.g. "Asia/Kolkata"), reported by the
-- browser, so reminders fire at their local clock time. Defaults to UTC
-- until the client reports a real zone.
--
-- sadhna_reminders_enabled: per-user opt-out for the daily reminders.
--
-- last_{chant,quote}_reminder_on: the UTC date a reminder of that kind was
-- last sent, so each kind goes out at most once per (UTC) day.
