/* ============================================================
 * theme_dark_modules.css —— 夜间模式（theme-dark）业务模块覆盖层
 *
 * 背景：chess-user 的夜间 token（--bg-card / --text-primary 等）已在
 *       css/theme_vars.css 就位，但大量业务模块把卡片底色写死为
 *       #fff / white / 浅灰，导致夜间模式下整页泛白。
 *
 * 策略：不动任何业务模块源码（87 个模块，且本地副本领先生产，
 *       直接改源码会产生冲突），改为在 theme_vars.css 之后追加本覆盖层，
 *       用 .theme-dark 前缀 + !important 精确压过写死的浅色底。
 *       选择器全部取自生产真实类名（已逐一核对，无臆测）。
 *
 * 评估依据：2026-11-09 夜间模式适配评估（87 模块全量运行时取证）
 *           报告 D:\docs\2026-11-09-夜间模式适配评估.md
 *
 * 生效范围：仅 body.theme-dark 时生效，白天模式零影响。
 * 维护：本文件在 css/theme_vars.css 之后加载（index.php 内 link）。
 *       后续新增模块白底问题一律追加到对应分节，勿散落各模块源码。

 *
 * 生产源码里大量文字色写死为深灰（#333 / #666 / #999 / #1f2937 /
 * #2c3345 / #5a6178 …）。这些在夜间深底上对比度不足 1.4，肉眼不可读；
 * 卡片改深底后更会彻底看不见。
 *
 * 本段把深灰文字统一提亮到夜间语义 token：
 *   --text-primary   标题 / 关键值
 *   --text-secondary 正文
 *   --text-muted     次要 / 计数 / 提示
 *
 * 生成方式：脚本扫描生产 modules/*.php 与 index.php 的 color 声明，
 * 取 RGB 各通道 ≤130 的深灰，按类名语义与原色深浅分三级。
 * 已排除：胜负/错误/成功等状态色、theme_vars.css 已有夜间色的选择器。
 * 白天模式零影响。

/* ============================================================
 * 分节 17 —— 夜间可读性补丁（2026-11-09 第二轮）
 * 触发：用户反馈 daily_practice 夜间模式下「灰色/紫色字看不清」。
 *
 * 根因一：分节 15「夜间文字提亮」把标题/数值按 primary/secondary/muted 三档批量降色，
 *        其中 secondary 档（#aaaaaa）用 !important 覆盖了分节 8 的 primary 档，
 *        导致 .dpr-card-t / .dpr-clock / .dpr-info-i .v 全部掉档变灰。
 * 根因二：模块源码里写死的深灰 / 深紫文字（#111827 #334155 #4c1d95 #7c3aed）
 *        在夜间底色（#1f2940 / #2a3550）上对比度只有 1.1~2.1:1，等于消失。
 * 根因三：浅底容器（白卡/浅色 chip）在夜间没压暗，而分节 15 又把里面的文字提亮成
 *        #e0e0e0 → 白底浅字，对比度 1.1~1.3:1，同样看不见。
 *
 * 手法：全部 .theme-dark 前缀 + !important，白天模式零影响。
