Datapack entries

Entries are ordinary datapack JSON under data/<namespace>/structure_encyclopedia/*.json. The server loads them and syncs the book to clients.

structure must be the exact registry id. /locate structure will tell you. minecraft:desert_pyramid is fine. yourmod:cool_dungeon is fine. A guessed name is not.

Required: structure, icon (item id), lore and description (translation keys). Optional: sort_order (lower first), mobs, loot_items, loot_tables, tags.

One page per structure id. To override a shipped page, replace the same path, for example data/structureencyclopedia/structure_encyclopedia/fortress.json, in a datapack that loads after this mod.

Display name, if you want one: "structureencyclopedia.name.yourmod.cool_dungeon": "Cool Dungeon". If you skip it, the client falls back to structure.<namespace>.<path>.

Write the lore like a page in a real book. Two sentences beat a bullet list of mechanics. Players already fought the place. They want to know what it was.
