Frontmatter

Every slide — .mdx, .md or .html — is configured the same way:

Field
slideLayout	default · cover · section · two-column · image-left · image-right · image-full · code · quote · statement
transition	fade · slide-left · slide-right · slide-up · zoom · none — this slide zooms in
background	a color, gradient or image URL — like the gradient here
class	extra classes, e.g. text-light
title	the title in the outline and go-to-slide dialog
notes	speaker notes
hidden	shown in dev, skipped in the built deck
