Slides Are A Document View, Not A Second ArtifactURL copied
demo/vyasa-slides.md is the best reusable example in the repo, because it explains the slide system in the same medium it uses. Slide decks are assembled in render_slide_deck() and vyasa/slides.py: ## splits horizontal slides, deeper headings become downward detail, and each slide gets a real URL. That means the normal document stays the source of truth while presentation mode becomes another route, not another file to maintain.
