Inventory Lite - Free Item Slots for Godot 4

Single-container item slots with stack merging, capacity checks, signals. Data layer for custom UI. 

Single-container item inventory for Godot 4.3+. Item Resource, slot capacity, stack merging. Free Lite tier of the SELODev Inventory addon.

The slot grid your game needs and the bag panel you didn't want to write. This Lite tier is the data layer - add, remove, check, count. Wire your own UI; we hand you the signals.

If you want a drop-in `InventoryUI`, drag-and-drop slots, hotbars, tooltips, weight + category enforcement, themes, and cross-system save/quest/vendor integration — see the **Pro tier**. Both tiers share the same item Resource field names so upgrading is a copy-paste.

### What you get (Lite)

- `ItemLite` Resource - id, name, icon, category, max_stack, metadata.

- `InventoryLite` Node - add/remove/has/count, capacity by slot count, stack merging by id + max_stack.

- Signals: `contents_changed`, `item_added`, `item_removed`, `slot_full`.

- `snapshot()` / `restore(data)` for your own save layer.

- Demo: 3 items, capacity 6, +1 / -1 buttons, live list.

Ready for the full system? Inventory (Pro) — $4.99, name your price — adds drop-in InventoryUI, drag-drop, hotbars, tooltips, weight/category gating, and save/quest/vendor integration.

Or get everything: Inventory is in the Inventory Cluster ($14.99, 4 systems) and the RPG Toolkit ($29.99, all 8) — both cheaper than the parts. Building more than one system? The bundle pays for itself on system #2.
