## \u2728 Primary Features
\n* \ud83d\udd12 **Persistent Storage:** Stored levels are linked to the player via scoreboards, meaning they persist through death and even if the book is lost or destroyed.
\n* \ud83d\udcc8 **Precision increments:** Full control with buttons for **1, 3, 10, or 30** levels.
\n* \u26a1 **Bulk Operations:** Rapidly clear your XP bar or withdraw your entire bank with **[STORE ALL]** and **[TAKE ALL]** buttons.
\n* \ud83d\udd0a **Dynamic Feedback:** Includes high-fidelity vanilla sound effects and color-coded chat messages to confirm every transaction.
\n* \ud83d\udee0\ufe0f **Universal Access:** Designed with the `\/trigger` system, allowing **Survival players without OP\/Cheats** to use the interface seamlessly.<\/p>\n

## \ud83d\udd28 Survival Crafting & Initialization
\nWe believe in “Vanilla+” balance. The recipe is expensive enough to feel earned, requiring 8 Bottles o’ Enchanting.<\/p>\n
**The Recipe Pattern:**
\n* **Outer Ring:** 8x Experience Bottles
\n* **Center:** 1x Regular Book
\n* **Output:** 1x Knowledge Book (Auto-converts to XP-Vault upon holding)<\/p>\n

## \ud83d\udcbb Technical Documentation (For Server Admins)
\nXP-Vault is built for stability and zero TPS impact. It avoids “Every-Tick” heavy NBT scanning, favoring a lightweight trigger-based architecture.<\/p>\n
### \ud83d\udcca Scoreboard Management
\nThe pack uses the following internal objectives:
\n* `exp_stored`: The master objective. Stores the player’s banked level count.
\n* `exp_current`: A temporary calculation buffer for XP bar data.
\n* `exp_takeX` \/ `exp_storeX`: Individual trigger objectives.<\/p>\n

\n* **Check a Player’s Bank:** `\/scoreboard players get

\nTo verify the pack is working correctly after installation:
\n1. Run `\/reload` and look for the “[Book of Experience] Datapack loaded” message.
\n2. Grant yourself 30 levels: `\/experience add @s 30 levels`.
\n3. Craft or give yourself the book and click **[STORE ALL]**.
\n4. Run `\/scoreboard players get @s exp_stored`. If it returns **30**, the system is 100% operational.<\/p>\n
\n* **1.21.x Component Migration:** Fully updated to the new `written_book_content` and `item_component` syntax (1.20.5+).
\n* **Recursion Optimization:** Rewrote the `take_all_loop` to handle massive level counts (1000+) without causing server hanging.
\n* **Syntax Hardening:** Replaced deprecated `clickEvent` keys with modern `click_event` formatting for 1.21.11 compatibility.
\n* **Auto-Conversion:** Improved the knowledge book detection logic to be more responsive.<\/p>\n
