-- Subscribed iCalendar (.ics) feeds.
--
-- doot reads Google Calendar with a service account, by calendar ID. That
-- cannot consume an .ics URL, and it cannot see a calendar subscribed to inside
-- a personal Google account either, because Google does not allow re-sharing a
-- subscribed calendar. Published schedules — sports fixtures being the case
-- that prompted this — are distributed almost exclusively as .ics.
--
-- Feeds are fetched on the normal calendar refresh and their events are merged
-- into calendar_events alongside Google ones, so they appear on the timeline
-- without the timeline needing to know they came from a different place.
--
-- last_error records the most recent failure and is cleared on success, so a
-- feed that has quietly stopped resolving is visible in settings rather than
-- just showing no events.
