+* On Linux, this typically resolves to `~/.config/bit_flipper/`.
+* On Windows, it will use the standard AppData folder.
+
+⚠️ **Sandboxed environments (Flatpak, Snap, etc.)** may redirect the config directory to a sandbox path.
+For example, when running inside Flatpak, the textures may be stored under:
