calendar_feed.py/calendar_render.py: fetch/merge per-user ICS feeds, render agenda/week/month views. manage_overlay.py: composites the manage-button overlay server-side (QR, battery, location/date, share-QR, face labels), reused by every render mode. device.py/common.py wire both together: mode dispatch for /frame/image+advance+back, and the &manage=1 flag. Plus UI (frame_config.html Calendar card, settings calendar URL field) and the icalendar/recurring-ical-events deps.
