SERVERS config near the top of the <script>.
Replace each bmId with your real BattleMetrics server ID (find it by searching
battlemetrics.com/servers/arksa for your server — the number in the URL is your ID).
Also replace YOUR.IP with your public IP or domain.
Once IDs are set, the page polls the free BattleMetrics API every 60 seconds automatically —
no API key required.
