-Fluxer publishes a `gateway_rollout` change to the Gateway cluster. Premium mode changes affect the limits in force without replacing the saved limit configuration. On self-hosted deployments, `everyone` hides premium-filtered rules. Switching back to `mirror` restores them unless an Admin has replaced the limit configuration in the meantime. Enabling single community mode creates the community when none is designated, with the acting Admin as owner.
