Gen1Recomp Windows (engine $Version) — native TLS

gen1tls.dll sits next to gen1recomp.exe and exposes a non-blocking TLS
client (Windows Schannel via .NET SslStream, Native AOT). Mods can load it
through LuaJIT FFI, or call love.system.tls* on Android.

Keep gen1tls.dll beside the executable when you redistribute the zip.
