DiamondShop

New Feature: Per-Slot Pricing Model

• Pricing Logic Updated: Shops now charge per item slot instead of per individual item.
  • Clicking a slot with a full stack (e.g., 64 items) now costs the same as a slot with a single item.
  • The buyer now receives the entire stack of items in the clicked slot upon purchase.
• Visual Payment Logic: When a purchase is made, the payment diamonds are now placed directly into the slot that was just emptied, maintaining an organized shop layout.
