/* 《人工智能与大语言模型》（Moallem、Degen、Ntoa 主编《Artificial Intelligence and Large Language Models: A Scientific Perspective》）2026-10-22 新增：
   对应兄弟目录 阅读-阅读与发芽/网站读书笔记/试排/261022-AI-LLM-Perspective-Artifact/ai-llm-perspective.html
   （概览卡＋“用不用大语言模型，先看两件事”题图、正文内目录、十三部分）。样式由 css/ai-all-in-one.css 换前缀而来。
   页面由根目录 reading_ai_llm_perspective_build.py 从试排页生成，不要手改正文；全部限定在 .ai-llm-perspective-notes 内，类前缀 llm-；
   小程序样式在 miniprogram/build_reading_notes.py 的 CLASS_STYLES（llm-*）。金色（--llm-gold）只用于书中原句和题图里的“高风险”；英文（lang="en"）用西文字体。
   防孤字：段落、条目末尾 4 个字在试排页生成时已包进 .llm-nb，不拆行。 */
