Create an ultra-efficient Minecraft...

Create an ultra-efficient Minecraft Iron Farm design that uses very low materials and works in Survival and Hardcore mode. I want a compact, minimal-cost, easy-build structure that produces extremely high iron rates (target: 5 stacks per minute by using multiple synchronized modules). Requirements: - Very small villager pods (3 villagers per module) - 1 zombie scare system that works 24/7 (name-tagged) - Fast golem spawning cycle (maximum speed allowed) - Multiple stacked modules so output becomes extremely high - Very low resource usage: glass, slabs, beds, water, lava, signs, and solid blocks only - Must include: • full top-down layout • side view • block-by-block blueprint • exact dimensions • villager placement • zombie placement • water & lava flow directions • hopper collection system • minimal spawn platform but 100% reliable - Design must avoid raid farm conflict, must avoid ground spawns, and work anywhere in a survival hardcore world. - Make the design look clean and symmetrical. - IMPORTANT: Output the design as a Minecraft build/schematic in .schem or .litematic compatible format.
