# DarkForge Linux — PipeWire service
# ============================================================================
# PipeWire audio server + WirePlumber session manager.
# NOTE: PipeWire is designed to run as a user service, not system-wide.
# This script prepares the runtime directory for the auto-login user.
# The actual PipeWire startup is handled in the user's shell profile
# (~/.zprofile) which starts pipewire, pipewire-pulse, and wireplumber.
#
# The auto-login user is detected from /etc/inittab (--autologin <user>).
