Inventories: stack, weight, slot

An inventory is a backpack with limited pockets and a scale. There are two dominant models in FiveM: slot-based, where each item lives in a numbered pocket, and weight-based, where only the total kilograms matter. Most modern systems use both at once. This lesson covers the two models and their trade-off, the stacking rules, item metadata, and how to integrate with ox_inventory without re-implementing it.

You'll learn: Slot vs weight model, stacking rules, item metadata, ox_inventory exports
Time: ~22 minutes
Prereqs: P1 (oxmysql), P9 (persistence)
Outcome: You can give a player 5 burgers, read the true count back from the inventory, and store unique metadata on an item so it stops stacking
