comark/carousel/unresolved-binding · Bind :zoom and :title to the document or its frontmatter

Each slide takes the carousel's zoom and title while the document is parsed. A :zoom or :title bound to a frontmatter key that doesn't exist, or to data and props that only arrive when it renders, gives the slides nothing, so the carousel has no title and keeps its zoom.
