Per request. /attendance is now a client view: a 'Here now' section with host badges + inline self check-in / check-in-as-host / check-out with a note; and a history with name search, a day picker, grouped-by- day headers, per-visit duration, status, notes, and a live visits/members summary for the current filter. New pure tested helpers dayKey (tz-stable UTC bucket) + visitDurationMinutes (+5 tests, suite 459).
