 # FEATURES: # FEATURES:
-#   - Verifies portable Python structure +#   - Checks: 
-#   - Enables "import site" +#       python.exe 
-#   - Creates required folders +#       pythonXY._pth 
-#   - Creates isolated launcher +#       import site 
-#   - Verifies user-site isolation +#       pip 
-#   - Displays sys.path+#       site-packages 
 +#       writable TEMP 
 +#       PYTHONHOME 
 +#       PYTHONPATH 
 +#       user-site
 # #
-# NOTES: +#   - Displays: 
-#   Python 3.14+ embeddable no longer +#       Python version 
-#   includes ensurepip by default. +#       Executable path 
-# +#       Pip version 
-#   pip may need to be copied manually +#       Site-packages path
-#   from another Python installation.+
