# services/shelfarr.nix — Shelfarr: Sonarr/Radarr-style search+acquire for
# audiobooks. Not in nixpkgs, so runs as a container like profilarr.
#
# Only the main app is deployed — the shelfarr-libation companion (Audible
# account backup) is skipped, beta and unrelated to indexer-based search.
# Ebooks volume also skipped (audiobooks-only use case); mount /ebooks later
# if that turns out to be required for the container to start cleanly.
#
# Prowlarr/qBittorrent hookup isn't wired into arr-interconnect.nix: unlike
# Sonarr/Radarr/Prowlarr/Bazarr, Shelfarr has no config.xml API key written
# before first boot — the first registered user becomes admin via the web UI,
# so that connection has to be made once by hand at
# https://shelfarr.nordhammer.it after first boot.
