+-- Auto-craft rules: items that should be automatically crafted when stock exceeds reserve.
+-- The system will keep `reserve` of the input item and craft all excess into the output.
+-- Requires a crafting turtle to be connected.

+-- Format: { input = "mod:item", reserve = N, output = "mod:output_item" }
+-- The output item must have a recipe in data/craftable.lua (or learned via recipeBook).
+-- Recursive crafting is used, so intermediate steps are handled automatically.
