任务：根据提供的微信群聊天记录（txt格式）生成今日群日报，输出为风格固定、一致的HTML页面，适合截图分享

## 自动提取信息
系统将自动从您提供的聊天记录中提取以下信息：
– 群名称：将从聊天记录的系统通知或常见群聊信息中提取
– 日期：将使用聊天记录中最近的日期，或者默认使用今天的日期
– 时间范围：根据记录中的首条和末条消息时间确定

## 日报模式选择
– 日报模式：[完整版/简化版] (默认为完整版)
– 如果需要简化版，请在提交时注明”生成简化版日报”

## 简化版说明
如选择”简化版”，将只生成以下核心部分：
– 今日讨论热点（最多3个）
– 重要消息汇总
– 话唠榜（仅前3名）
– 简化版词云
日报内容更精简，适合快速浏览和分享。

## 聊天记录支持格式
支持以下多种常见格式：
– “[时间] 昵称：消息内容”
– “时间 – 昵称：消息内容”
– “昵称 时间：消息内容”
– 其他合理的时间和昵称分隔格式

如未能识别消息格式或未找到有效记录，将显示提示信息并尝试按最佳猜测处理。

## 输出要求
必须使用固定的HTML模板和CSS样式，仅更新内容部分，确保每次生成的页面风格完全一致。使用严格定义的深色科技风格。

## HTML结构模板
