   memory-concepts.css — 刀 B-C3：概念工作台（静态壳）
   概念稿 §21.5 / 主线稿 §5.11

   ⚠️ 当前阶段（2026-08-01）：**生产 UI 已挂载 fixture 静态壳**
      （记忆索引台第 4 个 tab）。但边界未松：仍不接真实 route、
      不读概念 service、不接 reader 上下文、不消费 ambiguousAlias，
      数据全部来自注入的 fixture 适配器（见 memory-concepts.js 顶部）。

   规则（沿用 memory-desk.css 的既有约束）：
   - 所有类名 mconcept- 前缀，样式独立维护在本文件；
     style.css 本轮**只**删除了已废弃的旧 Memory Chain `.mc-*` 规则
   - AZOTH 真实主题变量集是 --bg / --text / --card-bg / --accent / --highlight / --shadow；
     --text-primary/--text-secondary/--border 任何主题都没定义。
   - 主文字一律继承 body（主题必然正确），次级文字用 opacity 弱化**不锁颜色**——
     fallback 写错比不写更糟（v1 暗色 fallback 在墟构白底上糊成浅灰的教训）。
   - 🔴 审美红线：**彩色左边条卡片全域禁用**。状态用小圆点 + 文字，不用色条。
