- * export_deck_pptx.mjs — 把多文件 slide deck 导出为 PPTX(图片铺底)
- *
- * 用法:
- * node export_deck_pptx.mjs --slides <dir> --out <file.pptx> [--width 1920] [--height 1080]
- *
- * 特点:
- * - 每张 slide 截图成 PNG,满铺一张 PPTX 页面
- * - 视觉 100% 保真(因为就是图片)
- * - ⚠️ 文字不可编辑(文字变成了图片)
- *
- * 如果用户需要「可编辑文字」的 PPTX:
- * ❌ 不要在 claude-design 的 HTML 上硬上 html2pptx——claude-design 的 HTML 视觉自由度高,
- * 很少能满足 html2pptx 的严格约束(p 标签语法、无 ::before、无 span margin 等)。
- * 实测 32 页里能 pass 的不到 30%,剩下的要逐页改造 + 逐页修字体溢出——工时失控。
- * ✅ 正确做法:切换到 **huashu-slides** skill 的 Path A,按它的 HTML 格式**从头重构**
- * 每一页。huashu-slides 的 HTML 从一开始就符合 html2pptx 约束,可 100% 导出可编辑 PPTX。
- *
- * 依赖:playwright pptxgenjs
- * npm install playwright pptxgenjs
- *
- * 会按文件名排序(01-xxx.html → 02-xxx.html → ...)
