# =========================================
# File: python_env_repair.ps1
# =========================================
# DESCRIPTION:
#   Portable Python Embeddable
#   Bootstrap / Repair Tool
#
# FEATURES:
#   - Verifies portable Python structure
#   - Enables "import site"
#   - Creates required folders
#   - Creates isolated launcher
#   - Verifies user-site isolation
#   - Displays sys.path
#
# NOTES:
#   Python 3.14+ embeddable no longer
#   includes ensurepip by default.
#
#   pip may need to be copied manually
#   from another Python installation.
#
# USAGE:
#
#   Default:
#   powershell -ExecutionPolicy Bypass -File .\python_env_repair.ps1
#
#   Custom path:
#   powershell -ExecutionPolicy Bypass -File .\python_env_repair.ps1 "D:\PortablePython"
