# ==============================================================================
# build-linux-app.sh
#
# Installs Odysseus as a native Linux desktop application (XDG spec).
#
# Prerequisites:
#   - venv built with server dependencies (uvicorn, fastapi, etc.)
#   - System PyQt6 with Wayland support installed via pacman:
#       sudo pacman -S python-pyqt6 python-pyqt6-webengine
#   - qt_wrapper.py present in repo root
#
# The display layer (qt_wrapper.py) runs under the SYSTEM python3 so it
# can use the system-built PyQt6/WebEngine with native Wayland support.
# The backend (uvicorn) runs under the venv python where all server deps live.
# ==============================================================================
