ARRFLIX/bin/add-jellyfin-user.sh

#!/usr/bin/env bash
# add-jellyfin-user.sh — create a Jellyfin user with the canonical s8n layout.
#
# Defaults applied:
#   - Home sections 0..9: resume, resumeaudio, nextup, latestmedia, none x6
#     (no "My Media" tile row — sidebar already exposes libraries)
#   - SubtitleMode=Default, SubtitleLanguagePreference=eng, AudioLanguagePreference=eng
#   - Non-admin policy with EnableContentDeletion=false
#   - LoginAttemptsBeforeLockout=5 (brute-force lockout after 5 failed attempts;
#     required since arrflix.s8n.ru exposed to public internet on 2026-05-08)
#   - EnableUserPreferenceAccess=false (hides Display/Home/Playback/Subtitles
#     pref pages — owner controls all UX defaults centrally; non-admins can't
#     change their own home layout, subtitle lang, etc.)
#
# Why this exists: Jellyfin has no native global default for new-user
# DisplayPreferences. The home-layout defaults are baked into the web bundle.
# This wrapper layers our preferences on top after user creation, so the same
# layout shows up for every user without anyone having to click through
# Settings → Display → Home Screen.
#
# Usage:
#   JELLYFIN_TOKEN=xxx ./add-jellyfin-user.sh <username> <password>
#
# Or interactive (will prompt for missing creds).
