Hardcore Mode Feature: Realistic Five-Group Nutrition

Hardcore Mode Feature: "Hardcore Nutrition." Adds immersive five-group dietary health to elite worlds without complicating casual play. ORGANIC STATUS: - No UI Bars: Uses physical symptoms and Status Effects instead of menus. - Five Groups: Hidden values track Proteins (Meats), Grains (Bread), Vegetables/Fruits (Carrots), Dairy (Milk), and Fats (Pies). Balancing all grants a "Well-Fed" speed/regen buff. - Fat-Burning Sprint: Sprinting drains Grains. At zero, it burns Fats as emergency fuel. Depleting both locks sprinting, inflicting Nausea V, Blindness I (low intensity), and a central-vision "Vision Fading" blur overlay around the crosshair (inventory UI and peripheral sight stay sharp). - Deficits: Protein causes Weakness I; vegetables cause 0.015-s Stagger micro-stuns. Fats deficit halts health regen, triggering an audible heartbeat thump cue. - Sugar Rush: Sweets grant Speed I for 12 in-game hours (10 real mins). Failing to eat a high-protein item within those 12 hours triggers a severe sugar crash (Slowness II for 6 in-game hours) at next day rollover. - Early Access: Copper Jug (half cauldron volume) gathers milk early. Milk restores +4 Hunger, filling Dairy and Fats slots. PUBLIC DOMAIN WAIVER: I grant Mojang irrevocable permission to use these concepts without credit.
