# The Windows counterpart of setup.sh (Linux/*BSD) and start-macos.sh (macOS):
# a fresh checkout goes to an installed app in one command. It:
#   1. checks for Python 3.11+ (guides you to install it if missing),
#   2. builds the venv, installs requirements.txt, and installs PyQt6/WebEngine
#      (via install.bat -> build-windows-app.ps1),
#   3. creates the Start Menu + Desktop shortcuts,
#   4. runs first-run setup (data dirs + initial admin password).
#
# Unlike Linux/*BSD, Windows uses pip-installed PyQt6 inside the venv (a single
# interpreter) — there is no system Qt to lean on — so no privileged step is
# needed once Python is present.
