v0.1.26: 墨规清辉——MOD 规范范式 + 灾因注册表 + 页面提亮（1047 全绿）

【MOD 规范与范式（核心命题）】
- docs/MOD_GUIDE.md：完整作者守则——命名/id 规约/semver/schema:1/五数据口
  （事件/模板/词库/灾因/配方）/依赖冲突/安全红线（无脚本·禁碰 rng·不动核心时序）/
  打包分发（.cotymod 单文件）/行为承诺
- validateMod 深度校验：category/weight/境界/负成本/非空/options.eff 形状
- modPreflight 权威冲突检测：findEvent（池+动态分支 raid/渡劫/大比/传薪全量）
- MOD_SCHEMA_VERSION=1 + schema 声明与升级提示；PluginStatus.author 展示

【灾因归一化（平衡版落地）】
- calamities 由 as const 死表→聚合注册表（calamityNames/calamityFamilyOf/calamityEffectOf+addCalamity）
- WorldSim 灾签/生产/Market 全链路走聚合读口——MOD 灾因（剑灾/灵潮湍变）进入世界循环
- 默认表不变→基准世界指纹零漂（clock.test 全绿实证）

【页面可读性（有点暗）】
- .dim #6d6150→#a99c80（3.4:1→7+:1）、.dim2 #96896e→#c3b595、.help-text 提亮、
  .feed-item 显色 #efe4c9 + 灰金系 8 处提亮（styles.css 12+/11- 纯色值）
- tests/contrast-readability.test.ts：WCAG 对比度审计（≥4.5:1）+ 历史暗色迁移断言

【测试】1047 全绿（47 套件）：mod-system 9（+validate/灾因/冲突/预检）、contrast 3；
【金钟罩】0.1.25 基线零漂；build 通过
