Extra Biomes XL 群系包
RTG 为 Extra Biomes XL 提供的群系包，共 28 个群系。
每个群系由一对类定义：BiomeConfig<Pack><Name>（配置面，落在 config/RTG/biomes/<pack>.cfg，见 群系配置属性）与
RealisticBiome<Prefix><Name>（生成面，落在 world/biome/realistic/<pack>/）。
| 项目 | 值 |
|---|---|
| 群系数 | 28 |
| 配置前缀 | extrabiomes |
| 宿主 modid | ExtrabiomesXL（Loader.isModLoaded 实测值） |
| 配置键格式 | <prefix>.<slug> |
| 配置类 | rtg.api.biome.extrabiomes.config.BiomeConfigEBXL（静态字段 holder，提供 getBiomeConfigs()）+ BiomeConfigEBXLBase（基类，携带 modSlug） |
群系一览（28）
「基础群系」是 RTG 复用的宿主 mod 原有 BiomeGenBase——RTG 自身不申请新的生物群系 ID，
只是接管该群系的地形、地表与装饰生成。数值全部逐类读自源码。
