+    Standalone MelonLoader IL2CPP mod whose ONLY job is to dump every
+    Google.Protobuf FileDescriptor that the running client has loaded.
+
+    It carries no Harmony patches, so it is safe to drop onto ANY Rec Room
+    build (2020, 2023, …) without the version-specific ClientMod patches
+    misfiring. Everything game-side is reached through plain
+    System.Reflection over the Il2CppInterop proxy assemblies, so no game
+    DLLs are referenced at compile time (they would be derivative works).
+
+    Build (desktop net6 MelonLoader, same pin as the ClientMod):
+
+      dotnet build DorkNet.ProtoDumper/DorkNet.ProtoDumper.csproj -c Release
+
+    Drop bin\Release\DorkNet.ProtoDumper.dll into <RecRoom>\Mods\ on a
+    MelonLoader-patched build and launch. Output lands in
+    <RecRoom>\DorkNet-ProtoDump\.
