# Notes:
#   - All commands and procedures are derived from my previous scripts and have been
#     specifically adapted for execution within a Flatpak Wine environment.
#   - Sets up Wine prefix, required libraries via winetricks, WebView2 runtime, DLL overrides,
#     and handles Autodesk installer execution with appropriate timeouts.
#   - Designed for a double-sandbox environment (Flatpak + Wine sandbox).
#   - EXE files must be placed inside the Wine prefix, as Wine cannot access $HOME directly.

# Note: The winetricks "sandbox" verb only removes desktop integration (e.g. autostart entries, menu shortcuts) 
# and the Z: drive symlink that normally maps your entire home directory. 
# This is not a "true" security sandbox, but rather a safeguard against misbehavior — 
# for example, preventing games from saving settings into random subdirectories of $HOME.
#
# In this setup, however, Wine is already running inside a Flatpak sandbox. 
# When you additionally enable the winetricks sandbox mode, you effectively get a "double sandbox":
#
#   1. Flatpak already restricts Wine's access to your system and isolates it from the host.
#   2. Winetricks "sandbox" further removes the Z: drive mapping inside the Wine prefix.
#
# As a result, Wine in this configuration has no direct access to your $HOME directory 
# or the host filesystem outside the prefix. 
# Therefore, executable files (EXEs) must be placed directly inside the Wine prefix, 
# since Wine no longer has permissions to reach outside of that sandboxed environment.
