不起完整客户端、不连服、不登录，只初始化 MC 渲染栈并喂入我们自己造的世界数据。
已验证（全绿）：
countRenderedChunks=29 distinct colors=1450
画面：草地/原木/树叶/天空/HUD/英文文字（sample-world-render.png）
打通的关卡：
- 反混淆（client-named.jar）+ GL 离屏 + new Minecraft(cfg) 不进主循环
- 资源同步重载：22 listener（ModelManager/FontManager/Dispatcher）
★ 不能 join reloadResourcePacks（等主循环→死锁），直接调各 listener reload()
- 注册表从客户端自带 data/ 加载（dimension_type=4）
- 区块注入：LevelChunk + setBlockState → ClientChunkCache.Storage.chunks
+ LightEngine.queueSectionData（全亮）→ allChanged()
- 每帧 mc.tick() 推进网格重建队列（不跑则 countRenderedChunks=0）
踩坑记录（10 条，README 详列）：
LoadingOverlay/ReceivingLevelScreen 遮挡、FolderData 参数序、
assetIndex 用落盘名、reloadShaders 包私有、读像素必须绑 FBO、
判据用 distinct colors 而非 non-black
更正附录 D：state_id=1003 → note_block 不是误映射（note_block 有 800 状态）
—— 真客户端给完整状态，是 1.20.1 上 mod 方块语义的唯一权威来源
