REM 1. Detect CPU architecture and pick the best-fitting embedded Python build.
REM 2. Download & extract that build into .\embedded_python\
REM 3. Bootstrap pip via install-utils\get-pip.py
REM 4. Install virtualenv and create .\talemate_env\ using the embedded Python.
REM 5. Activate the venv and proceed with Poetry + frontend installation.
