## Quick Reference

| What you want | Where to put it |
|---|---|
| A room | `data/rooms/<id>.yaml` |
| An item (sword, ore, key) | `data/items/<id>.yaml` |
| A mob (NPC, monster) | `data/mobs/<id>.yaml` |
| An interactive object (rock, lever, door) | `data/objects/<id>.yaml` |
| A shared drop table | `data/drops/<id>.yaml` |
| A crafting recipe | `data/recipes/<id>.yaml` |
| A help topic | `data/help/<id>.yaml` |
| A science module | `data/modules/<id>.yaml` |

Behaviors (gather, talk, use) are defined **inline** in object and mob YAML
under `gather:`, `talk:`, or `use:` keys. There is no separate behavior directory.
