@REM Abstrakt v6 silent install script (prod)
@REM Fetches the current version from prod.yml, downloads the installer, and installs silently.
@REM Prod is a per-machine install -> requires Administrator. Self-elevates if needed.
@REM
@REM To deliver to customers: rename this file to install-abstrakt.bat and email it.
@REM The script self-elevates via UAC, so customers just double-click it.
