 * @author La-Li-Lu-Le-Lo (@lalilulel0z) formerly BasedToschi - Glue Finance
 * 
 * @notice Centralized constants for the Glue Protocol
 * @dev All Glue Protocol contracts inherit from this to access core constants
 * 
 * 🔧 **What's Inside:**
 * - ✅ **GLUE_STICK Addresses**: Official protocol addresses for ERC20 and ERC721 glue factories
 * - ✅ **ETH_ADDRESS**: Constant for representing native ETH in protocol operations
 * - ✅ **DEAD_ADDRESS**: Standard dead address for burning tokens
 * - ✅ **PRECISION**: 1e18 precision constant for calculations
 * 
 * ⚠️ **CRITICAL - DO NOT MODIFY:**
 * The GLUE_STICK addresses are immutable and protected by the BUSL-1.1 license.
 * Modifying these addresses constitutes a license violation and breaks protocol compatibility.
 * 
 * 📦 **Used By:**
 * - GluedToolsBase
 * - GluedToolsERC20Base
 * - StickyAsset (via GluedToolsBase)
 * - InitStickyAsset (via GluedToolsBase)
 * - GluedTools (via GluedToolsBase)
