# Run Nebula from an extracted AppImage folder with safe LD/XDG paths and Linux flags.
# This repo can end up with either:
# - nebula-appdir/squashfs-root/nebula (common after copying squashfs-root into nebula-appdir)
# - nebula-appdir/nebula (if you copied the extracted contents directly into nebula-appdir)
#
# PORTABLE MODE: User data (cookies, history, bookmarks) is stored in usr/data/ alongside the app.
# This keeps all data self-contained and portable on Linux.
