- F21-01: plan_ready and list_ready links carry their week (/plan?week=, /plan/shopping?week=), and the Plan opens on ?week= and keeps it on the week shown, so an older update opens its week. - F21-02: a failed refresh of the Rotation check shows its ErrorBanner beside the cached pending card instead of replacing it. - F21-03: Home carries the household's timezone and is read again at its next local midnight. - F21-04: Home counts pending Side quests through a read-only query (suggest.PendingCount), so reading Home never writes batches.
