Material repairs now scale their capped XP charge by ingredients actually consumed divided by the item crafting-material count: pickaxe/axe 3, sword/hoe 2, helmet 5, chestplate 8, leggings 7, boots 4, shovel 1. Fractions round up; tool-to-tool repairs retain normal capped prices. Added max-additional-enchantment-levels config (default 0) for opt-in higher-level anvil merges while retaining compatibility checks and existing over-level items. Updated documentation and admin setup instructions.
