Custom Banner Pattern Builder
Build a data-driven banner_pattern JSON file — asset ID and translation key — for a custom banner design in a resource pack + datapack combo.
These builders target Minecraft’s 1.21+ data-driven JSON registries. Some schemas (mob variants, dialogs) are newer and still evolving — double check against the current version’s vanilla data before shipping.
