+# html-to-pdf.sh —— 把 Beautiful Article 的单页 HTML 转成 PDF
+#
+# 用法：
+#   bash <skill>/scripts/html-to-pdf.sh [input.html] [output.pdf]
+#   bash <skill>/scripts/html-to-pdf.sh                       # 默认 article/article.html → article/article.pdf
+#   bash <skill>/scripts/html-to-pdf.sh --help
+#
+# 前提：本机已装 Chromium / Google Chrome / Brave / Microsoft Edge 之一
+# （脚本会自动探测）。无需 npm 包、无需 Node。
+#
+# 设计要点（详见 references/pdf-output.md）：
+#   1. reacticle 默认 TOC 在桌面是左右栅格；PDF 需要 TOC 上、正文下的上下排布。
+#   2. 脚本在 HTML 头部注入一段 @media print CSS 覆盖：把 TOC 塌成一列、解除
+#      sticky、长 TOC 双列省纸、TOC 后强制分页、隐藏 colophon 之外的页眉页脚等。
+#   3. 用 headless 浏览器 --print-to-pdf 渲染（执行页面 JS，Raw 交互渲染为初始
+#      态）；输出标准 A4 / 主题纸色满版背景 + 0.45in 内容留白，无浏览器自带页眉页脚。
+#   4. 失败回退：打印"用浏览器手动 Cmd+P → 另存为 PDF"指引，并把注入后的 HTML
+#      留在临时目录方便用户自己打印。

+/*
+ * PDF print overrides for Beautiful Article.
+ *
+ * Injected by scripts/html-to-pdf.sh into article.html's <head> right before
+ * Chromium headless prints it. reacticle's own print.css already handles
+ * hiding export bars and break-inside on cards.
+ *
+ * This file adds four groups on top of that:
+ *   0) Theme surface — keep the article theme background / text colors in PDF.
+ *   A) TOC layout — force the sidebar TOC to stack above the article and
+ *      page-break after it, so the article body starts on a fresh page.
+ *   B) Page break behavior — undo reacticle's `.ra-section { break-inside:
+ *      avoid-page }` (which causes huge empty pages for multi-page sections),
+ *      glue headings to the following content, keep Hero / Lead / figures
+ *      atomic, and apply widow/orphan control to paragraphs.
+ *   C) Cover — if the article uses the 3:4 Cover component (default), keep
+ *      its authored geometry intact and only force a page break after it.
+ *      See references/cover.md.
+ *
+ * Why a separate file:
+ *   - macOS BSD awk rejects multi-line strings via -v; reading from a file
+ *     with getline sidesteps that.
+ *   - CSS is independently editable / lintable / diff-friendly here.
+ *   - Easy to swap or extend without touching the shell script.

+"""Source → Markdown extraction helper for the Beautiful Article skill.
+
+Mechanically extracts text from a PDF / DOCX / HTML file (or URL) into rough
+Markdown. It does NOT clean editorial noise, mark image placeholders, or record
+extraction risk — that judgement stays with the agent (see Phase 1 +
+references/source-to-markdown.md). The agent should review and refine the output
+into source/source.md and write source/extraction-notes.md.
+
+Usage:
+    python3 source-to-markdown.py <input.pdf|.docx|.html|.htm|.txt|.md|URL> [-o out.md]
+
+Dependencies are probed at runtime and optional. If a parser is missing the
+script prints an install hint and degrades gracefully.
