Notes

• Uses itzg/minecraft-server with AUTO_CURSEFORGE type — it auto-downloads the modpack from CurseForge on startup if not already present
• Modpack: TerraFirmaGreg: Modern (MC 1.20.1), pinned to a specific file ID (7665541)
• Memory: 8 GB initial, 12 GB max (hard limit via mem_limit: 12g)
• Auto-pause is enabled — server pauses after 30 minutes with no players, resumes on connection
• MAX_TICK_TIME: -1 disables the watchdog timer (prevents server shutdown if a tick takes too long, common with heavy modpacks)
