// doc-convert.rhai — md_to_html / md_to_pdf / html_to_pdf demo.
//
// Usage: recon --script doc-convert [MD_PATH] [PDF_OUT]
//
// 1. Read a markdown source (CLI arg or Cargo.toml as fallback demo).
// 2. Convert to HTML with a linkable TOC.
// 3. Optionally convert to PDF via agent-browser (skipped gracefully
//    when agent-browser isn't installed).

// Load markdown. `file_read` returns a Blob; `Blob::to_string()` yields
// the hex-debug view, not a UTF-8 decoded String — `md_to_html` would
// silently render the hex bytes as a giant paragraph. Use `text::decode`
// to get the real text body.

// 3. One-shot md → pdf with a different destination. Insert `-2`
// before the `.pdf` extension so the file still opens with a normal
// PDF viewer (writing `.pdf.2` confuses macOS / Finder).
