# NoCloudPDF — strip macOS source-tracking metadata from files.
#
# What it removes:
#   com.apple.metadata:kMDItemWhereFroms  (the URL the file came from)
#   com.apple.quarantine                  (downloaded-from-internet flag)
#
# Setup (one-time): browsers don't preserve executable bit on download, so:
#   chmod +x ~/Downloads/strip-meta.command
# After that: drag PDFs onto the icon, or double-click for interactive prompt.
#
# Note: for a single file, you don't need this script at all — just run
#   xattr -c yourfile.pdf
# directly in Terminal. This script's value is the drag-drop UX for repeated use.
