Yueyue Structure Block Fixes

Version 1.0.4 for Minecraft 26.3. Preserves structure-block templates' saved waterlogged states instead of automatically filling originally dry stairs, slabs, signs or fences from nearby/target water. Existing wet states stay wet; later normal fluid updates still apply. Only structure-block loading is changed, not natural structures or every template caller.

With Fabric Carpet installed, corner detection follows max(80, structureBlockLimit + 1), including the extra boundary corner. Waterlogging preservation works without Carpet. Install on the logical server: local client installation covers singleplayer; a remote server needs it server-side. This file targets Minecraft 26.3.

中文：结构方块加载时保留文件记录的干湿状态，修复原本不含水的方块被错误灌水。安装Carpet后角落检测跟随structureBlockLimit规则，无Carpet时含水修复仍有效。应安装在实际运行世界的服务端；26.3文件不能用于其它版本。

English operation guide

Save a structure normally, then load it using a structure block; waterlogging preservation applies automatically with no additional toggle. Dry/wet stairs, slabs, signs and fences retain the template's saved waterlogged property even when the destination or neighboring blocks contain water. Later normal fluid/block updates continue to work.

If Fabric Carpet is installed, use its existing structureBlockLimit rule as usual; the corner search uses max(80, structureBlockLimit + 1) to include the extra boundary corner. Without Carpet, only that range integration is inactive; the waterlogging fix remains independent. This does not change natural structure generation or unrelated template callers. Use the 26.3 file only in Minecraft 26.3. For singleplayer install locally; for multiplayer install on the server actually running the world.

中文使用说明

月月结构方块补丁 1.0.4修复结构方块加载时的含水状态问题：原先干燥的牌子、楼梯、半砖、栅栏等，即使目标位置或邻面有水，也按模板中保存的 waterlogged 状态放置；原先含水的继续含水。

• 正常保存结构后，再用结构方块加载即可生效，不需要额外开关。补丁只作用于结构方块触发的模板加载，不把所有自然结构生成或其它模组模板调用都改掉。
• 加载完成后的自然水流与方块更新仍照常发生；此功能不是永久防含水或永久免更新。
• 安装 Fabric Carpet 后，角落检测搜索范围跟随 max(80, structureBlockLimit + 1)，包含边界角落。没有 Carpet 时，含水修复仍独立生效。
• 单人安装在本地即可作用于集成服务端；多人必须在运行世界的服务端安装，只有远程客户端安装无效。当前文件仅用于 Minecraft 26.3 / Java 25 / Fabric，不要用于其它游戏版本。

Runtime and dependencies

• Minecraft 26.3 / Java 25 / Fabric Loader 0.17.3+. No hard Fabric API or Carpet dependency; Carpet only enables the rule-driven corner-range integration.
• Client: Install for singleplayer; optional on remote clients
• Server: Required on logical server for effect
• carpet: optional — Rule-driven corner detection; waterlogging patch standalone
