# ================================= Arr Cleanup Launcher =======================================
# ==============================================================================================
#
# PURPOSE
# ─────────────────────────────────────────────────────────────────────────────
# Thin bash launcher for arr_cleanup.py. Handles everything bash is uniquely
# suited for: sourcing shell config, detect_hosts(), exporting env vars.
# All logic lives in Python.
#
# USAGE
# ─────────────────────────────────────────────────────────────────────────────
#   arr_cleanup.sh --arr lidarr [--dry-run] [--log] [--status]
#   arr_cleanup.sh --arr radarr [--i-know-what-im-doing] [--skip-strike-list]
#   arr_cleanup.sh --arr sonarr
#
# ADDING A NEW ARR
# ─────────────────────────────────────────────────────────────────────────────
#   1. Add HOST*_<ARR>_URL, API_KEY, MEDIA_ROOT, PATH_MAP to host*.conf
#   2. Add <ARR>_ORPHAN_AGE, MAX_DELETE_GB, EXTENSIONS, etc. to master.conf
#   3. Add a profile entry to ARR_PROFILES in arr_cleanup.py (6 values)
#   4. Add an export block for the new arr below (copy Sonarr block, change prefix)
#
