Latitude 1.3.0 for Minecraft 1.20.1

Latitude 1.3.0 is now available for Minecraft 1.20.1.

This is a backport of the 1.3.0 Latitude update, bringing the newer climate/worldgen system, bespoke UI work, loading-screen polish, HUD tools, and EW border improvements to the 1.20.1 line.

Highlights

• Backported Latitude 1.3.0 to Minecraft 1.20.1.
• Restored the 1.3.0 climate and biome-selection improvements on 1.20.1.

• Restored the bespoke create-world flow and “Begin Expedition” launch path.
• Restored Latitude’s bespoke loading overlay for new and existing worlds.

• Fixed 1.20.1 client/UI API drift across settings screens, HUD Studio, create-world screens, and render hooks.

• Preserved /latdev developer tools for inspection and proof checks.
• Verified fresh-world and existing-world runtime loading.
