Authoring dungeons

Pack layout:

config/epicquest_dungeoning/
  dungeons.json
  images/          optional preview PNGs
  dungeons/<dungeon_id>/
    structures/<namespace>/.../*.nbt
    worldgen/template_pool/<namespace>/*.json

Register each dungeon in dungeons.json with a required jigsaw object (start_pool, start_jigsaw_name, size, max_distance_from_center, fallback_pool, optional unique_templates).

Building pieces:

• Structure Block SAVE mirrors into the pack under config/.../structures/.
• Put a Dungeon Player Spawn in the start/anchor piece.
• Put a Dungeon End Pad only if you use reach_end completion.
• Keep at least one small dead-end in fallback_pool.

Completion types: kill_entity, collect_items, or reach_end. Omit completion to disable auto-triggers; the return button, API, and /dungeon complete still extract.
