ItemBound
Minecraft 26.1

Items counted: 1385

Install:
1. Create a new Minecraft 26.1 world.
2. Put this ZIP in the world's datapacks folder, or add it during world creation.
3. Join the world. The border starts automatically around the first non-spectator player.

Rules:
- The counter is shared globally.
- Each item ID can score exactly once for the entire world.
- If two players obtain the same new item at nearly the same time, only the first claim scores.
- Every unique item expands the border by 1 block on each side, which is +2 to the border diameter.
- New players see the same shared bossbar and progress.
- The item pool is version-specific.

Commands:
 /function itembound:status
 /function itembound:reset

Dimension behavior:
- Overworld and Nether have independently synchronized borders. The End is left unrestricted.

Notes:
- Item variants that share one registry ID, such as different potion contents, count as one item ID, matching ItemBound's item-ID style.
- Creative-only and technical items are not in the pool.
