.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.
