Auto-Stacking
Unlike other stack-size datapacks, Stackable Items automatically consolidates your inventory. Pick up a second boat and it merges into your existing stack
Note: Items with variant data (potions, tipped arrows, suspicious stew, goat horns, bundles) get the increased stack size but must be manually combined to preserve their unique effects/contents.

Safe by Design
intentionally does NOT modify:
Tools, armor, enchanted books, written books, maps, shields, bows, crossbows, elytra, music discs, banners, or player heads.
These items carry unique NBT/component data and modifying their stack size would cause item data loss.
