+#Requires -Version 5.1
+<#
+.SYNOPSIS
+    Launches OBS Studio hidden with the replay buffer running, then starts the tray icon.
+    Intended to be called by DEM as a logon task (fire and forget — do not wait for completion).
+
+.NOTES
+    Reads settings from config.psd1 one level above this script.
+    Writes the OBS profile basic.ini dynamically so the correct UNC path and buffer
+    duration are baked in at session start.
