modpack-final.zip is 78MB, well over Gitea's upload limit. Served directly from Caddy's existing static/ mount instead (path-routed within the minecraft.mivanchenko.de block, alongside the BlueMap failover) - no new container or mount needed. install.sh/install.ps1 MODPACK_URL updated accordingly; install scripts themselves stay on Gitea since they're small text files. Verified full byte-exact download end-to-end. Also drops the stale "moving to the venue" comments now that the server is permanently on mivanchenko.de.
