What this deck builder supports: slide kinds, body block types, capacity limits and the brand palette. Call this before writing deck Markdown for the first time.

Parse deck Markdown and report the slide outline plus layout warnings (overflow risk, too many cards, missing titles) without rendering a file. Cheap — use it while drafting.

Render deck Markdown into a True-branded .pptx. Returns an artifact_id — pass it to deck_preview to look at the result and to deck_fetch to get the bytes. Regenerate from edited Markdown rather than editing the .pptx.

Render a generated deck to images so you can actually see it. Returns a contact sheet by default, or individual slides. Look for text spilling out of a card, a nearly empty slide, or a badly wrapped title, then fix the Markdown and regenerate.

Return the generated .pptx itself as an embedded resource, for hosts that cannot fetch a download URL. Large files are refused — use download_url or file_path instead.
