Terracarts: Vanilla-Friendly Cars

Vehicles, Customization & Loot

• 4 Cart Tiers & Unique Models: Added Standard, Swift, Sturdy, and Prime — each featuring brand-new custom 3D models, unique stats, and uncraftable tier cores found as rare loot in structure chests.
• In-World Customization: Replaced 16 separate colored cart items with dynamic in-world dyeing (all 16 dyes) and sponge paint stripping.
• Survival Economy: Standardized fuel strictly to pure Coal (+15 FU) and repairs to Iron Ingots (+15 HP), both with anti-waste protection.

Physics, Driving & Collisions

• Smooth Movement & Dynamics: Overhauled movement physics for butter-smooth driving, natural slope climbing, and realistic airborne momentum and knockback impulses.
• Transmission & Braking: Added reverse gear with tier-based speeds, smooth shifting transitions, and dedicated braking with dynamic squeal audio.
• Complete Collision Overhaul: Added brand-new cart-to-cart (C2C) collisions, universal crash consequences (safe bumps vs high-speed crashes with fuel leaks and stun), and expanded entity interactions (mobs, primed TNT, crystals, armor stands).
• Environmental Hazards: Added foliage drag through leaves, shallow water resistance, deep water engine flooding/sinking, and fire/lava damage.

Visuals, Audio & Polish

• Audio & Animations: Overhauled sound logic with tier-specific engine hums, shift clicks, and water sputters; added client-synced steering animations, reverse steering fixes, and improved particle effects.
• HUD & Optimization: Enhanced the in-ride dashboard to blend with tiered stats, optimized overall mod performance, and smoothed out multiplayer/Replay mod syncing.
• Branding & Documentation: Renamed mod display name to Terracarts, updated fabric.mod.json, refreshed LICENSE.md, and completely rewrote README.md.
