## Rollback — three concrete commands

```bash
SNAP=/tmp/ARRFLIX/snapshots/2026-05-08-pre-elegantfin
TOKEN="<JELLYFIN_API_TOKEN>"
BASE="https://arrflix.s8n.ru"
```

### 1. Restore CustomCss + LoginDisclaimer (branding)

```bash
curl -ksX POST "$BASE/System/Configuration/branding" \
  -H "Authorization: MediaBrowser Token=$TOKEN" \
  -H "Content-Type: application/json" \
  --data-binary @$SNAP/branding.json
# Expected: HTTP 204
```

### 2. Restore the bind-mounted index.html on nullstone

```bash
scp $SNAP/index.html user@nullstone:/opt/docker/jellyfin/web-overrides/index.html
# No restart needed — Traefik serves the file directly via the bind-mount.
```

### 3. Restore per-user DisplayPreferences

```bash
for uid in 571decc67cdc4ea683b4c936b0a31ff8 \
           82dd8542915740c8ae799b6723542c63 \
           a4cbcdf95bb34888885af6fbf5c340d1 \
           d787fbfc373a44119a247e7406b2721e \
           2be0f0d3fe3a45dc9298138a15a01925; do
  curl -ksX POST "$BASE/DisplayPreferences/usersettings?userId=$uid&client=emby" \
    -H "Authorization: MediaBrowser Token=$TOKEN" \
    -H "Content-Type: application/json" \
    --data-binary @$SNAP/displayprefs-$uid.json
done
# Expected: HTTP 204 each
```

---

## One-shot rollback (all three at once)

```bash
SNAP=/tmp/ARRFLIX/snapshots/2026-05-08-pre-elegantfin
TOKEN="<JELLYFIN_API_TOKEN>"
BASE="https://arrflix.s8n.ru"

# 1. branding
curl -ksX POST "$BASE/System/Configuration/branding" \
  -H "Authorization: MediaBrowser Token=$TOKEN" \
  -H "Content-Type: application/json" \
  --data-binary @$SNAP/branding.json

# 2. index.html
scp $SNAP/index.html user@nullstone:/opt/docker/jellyfin/web-overrides/index.html

# 3. per-user displayprefs
for uid in 571decc67cdc4ea683b4c936b0a31ff8 82dd8542915740c8ae799b6723542c63 \
           a4cbcdf95bb34888885af6fbf5c340d1 d787fbfc373a44119a247e7406b2721e \
           2be0f0d3fe3a45dc9298138a15a01925; do
  curl -ksX POST "$BASE/DisplayPreferences/usersettings?userId=$uid&client=emby" \
    -H "Authorization: MediaBrowser Token=$TOKEN" \
    -H "Content-Type: application/json" \
    --data-binary @$SNAP/displayprefs-$uid.json
done
```

## Reference (read-only — for diffing, not posting back)

- `users.json` — sanity-check that policies/permissions match before/after a future user-mgmt change. The User API uses `/Users/{id}/Policy` and `/Users/{id}/Configuration` endpoints, NOT a bulk POST.
- `libraries.json` — sanity-check that VirtualFolders are still intact. Library mutations go through `/Library/VirtualFolders` add/remove endpoints, not a single POST.
- `docker-compose.yml` — reference only. If the compose file changes, restore by hand and `docker compose up -d` on nullstone.

## What this snapshot does NOT cover

- Jellyfin SQLite databases (`library.db`, `users.db`, etc.) — full data is preserved by Restic backups, not this snapshot.
- Plugins / plugin config — not part of the CSS/branding migration scope.
- Media files on disk — never touched by theme work.

If a recovery requires DB-level restore, fall back to the Restic snapshot job
documented in `SYSTEM.md` rather than this CSS-scoped rollback.
