# Preparación del ENTORNO DE DESARROLLO en Windows: verifica Python/7-Zip/ODBC del
# sistema, crea el venv e instala requirements.txt para correr `python runner.py`.
#
# NO es el instalador de despliegue. Para instalar el binario compilado en un servidor
# usa install.ps1 (raíz del repo), que es autocontenido y no necesita nada de esto.
