Three-tab Bubble Tea TUI (Setup / Manage / Monitor) for setting up and running a headless Jellyfin server over SSH: - Setup: install/uninstall Jellyfin, add media drives (single or btrfs RAID pool), import an existing detached btrfs pool non-destructively, firewall, move Jellyfin storage onto a media drive - Boot-drive-safe drive classifier (walks LUKS/LVM/RAID to the physical disk; never offers a disk hosting /, /boot or swap) - Keep-existing-filesystem path previews on-disk content, skips starter folders when content exists, and grants Jellyfin recursive read access - Manage: copy from external drives, mount/eject, rename/delete - Monitor: per-core CPU, load/mem/uptime, btrfs error counters, SMART Single static binary; installs to /usr/local/bin so sudo can find it.
