Perfect solvable grid-based Minecra...

Perfect solvable grid-based Minecraft maze schematic, Java 1.21. Rectangular 64x64 base, 20 block height. Mix easy wide paths, medium twisting corridors with dead-ends, and hard complex sections. Include vertical navigation: stairs, ladders, drops, small tunnels, rooms, massive cavernous expanses and crevices. Walls: 2 blocks thick using stone bricks, deepslate bricks, mossy cobblestone. Floor: stone with gravel/slabs. Ceiling: 4 blocks high with lanterns. Paths: exactly 2 blocks wide, fully navigable with one main solution path plus many loops and dead-ends. Add scattered chests with torches, food, pickaxes, swords, bows, arrows, potions, armor — better loot in deeper/harder areas. Clear entrance and central goal room. Ancient dungeon style, clean and fully playable.
