Putting anything up offline starts a solo session: an in-app server bound to 127.0.0.1 only, joined like hosting, so tracking, next episode and the player all work. Invite friends re-hosts on the Host card's port and password with the same media and position; Stop needs no confirmation. Offline, the Library opens with a welcome band (Join a friend, Host, Watch solo); without a Jellyfin account it leads with Files and Link, Jellyfin is an optional card. Play buttons work offline.
