Inventory GUI

• Vanilla chest-style interface
• Scrollbar + mouse wheel for tiers larger than 7 visible rows
• Middle-click sort: merge stacks, A→Z by item id, full stacks before leftovers (e.g. 65 → 64 + 1)
• Shift-click / quick-move across the full backpack (including scrolled-off slots)
• Locked hand / equipment slot while the GUI is open so items are not voided

World interaction

• Shift + right-click to place a backpack
• Right-click placed backpack to open
• Shift + right-click placed backpack to pick up with contents intact
• Block drops and pick-block keep stored inventory

Equipment & controls

• Equip on the vanilla chestplate slot
• Optional Curios: equip on back and chest slots
• At most one backpack worn at a time (chest or Curios, never both / never two Curios backpacks)
• Default keybind B opens the equipped backpack (remappable)
• Empty-hand right-click in air opens the worn backpack
• On-body rendering for chest and Curios equipment

Collision

• Per-tier selection/collision shapes based on each backpack model AABB (not a full cube)

Compatibility

• JEI (optional): backpack crafting recipes shown as crafting
• Jade (optional): placed backpack contents preview (hold Shift)
• Curios (optional): soft dependency for wear / render / open
• Mouse Tweaks (optional): GUI drag support; wheel tweak disabled in the backpack screen so scrolling works

Localization

• English (en_us)
• Brazilian Portuguese (pt_br)

Notes

• Worn pose (scale, offsets, rotation) can be tuned in code via BackpackBodyPose for pack maintainers.
• This is the first public feature set for 1.0.0.
