+"""
+Terraria log filter for Umbrella (vanilla, tModLoader)
+
+Vanilla and tModLoader produce fairly clean output, so this filter
+mostly just strips blank lines and tModLoader's internal loading/debug
+noise during startup.
+
+Vanilla format:  plain text, e.g. ": <Player> has joined."
+tModLoader format varies; startup emits many mod loading lines.
+
+Install: /usr/lib/umbrella/filters/terraria.py
+Unit YAML: log_filter: /usr/lib/umbrella/filters/terraria.py
