-Place Tor.xcframework here
-
-Instructions
-- Obtain a prebuilt Tor Apple xcframework (iCepa/Onion Browser lineage) or build your own minimal client-only Tor.
-- Rename it (if needed) to `Tor.xcframework` and drop it in this `Frameworks/` directory.
-- Regenerate the Xcode project if you use XcodeGen (`project.yml` already references `Frameworks/Tor.xcframework`).
-- Build the app; `TorManager` will automatically bootstrap Tor and route all networking through it.
-
-Notes
-- For iOS, the framework will be embedded and code-signed automatically.
-- For macOS, it will be linked and embedded as well (you may prefer a system tor for smaller bundles).
