The Emerald Book

• Added a rare Emerald Book item that sits in the Tools and Natural Blocks tabs and can be crafted from a book, two emeralds, and an ender pearl.
• Opening the book teleports you into the new Emerald Realm dimension; using it there brings you back to your last recorded position, falling back to your world spawn if needed.
• The Emerald Realm is a flat, always-day landscape of emerald blocks with a cleared landing platform and soft lighting so you arrive safely.
• Villagers and iron golems populate the landing area whenever it is quiet, reinforcing the idea of an inhabited emerald refuge.
• The book uses layered vanilla book and emerald visuals, custom names, and flavor text explaining how to travel.

Notes and limits:

• The realm is intentionally simple: no natural structures or ores beyond emerald blocks, and only villagers/golems spawn by default.
• If the target dimension is still loading you’ll see a status message and can try again once the world is ready.
