Guide

• Full Client/Server Decoupling — Completely refactored the mod's class hierarchy to strictly separate client-side GUI and rendering logic from server-side data and networking. All screens, renderers, and input handlers are now annotated with @OnlyIn(Dist.CLIENT), preventing any accidental classloading on dedicated servers.

• Safe Screen Opener Proxy — Introduced GuideScreenOpener as a client-only bridge to safely instantiate screens without exposing Screen subclasses to server code, eliminating BootstrapMethodError crashes when opening the guide book.

• Cleaned Event Bus Registrations — Removed manual MinecraftForge.EVENT_BUS.register(PlacementProjector.class) from the mod constructor, relying solely on the automatic @Mod.EventBusSubscriber annotation with value = Dist.CLIENT. This ensures projection logic never loads on a dedicated server.

• DistExecutor-Free Invocation — Replaced risky DistExecutor calls in ModItems with a safe call to the client-only GuideScreenOpener, guaranteeing zero classloading violations when the book item is used on a server.

• Network & Quest Sync — Maintained full SimpleChannel networking with proper server-authoritative quest state handling and client synchronization, keeping multiplayer functionality intact.

✅ Servers no longer crash on startup when Guide is installed.

✅ Mod can be safely added to any Forge 1.20.1 modpack without server-side issues.

✅ All client features (GUI, projection, sounds, mob renderers) remain fully functional in singleplayer and on servers for connected clients.
