What the Markdown includes

The balanced Markdown keeps slide titles, paragraphs, bullets, tables, chart data, speaker notes, important shape text, SmartArt text, and content image references.

When to use compact Markdown

The package also includes `content.compact.md` for limited context windows. It keeps core text, tables, chart data, notes, and SmartArt text while skipping image references and native shape text blocks.
