/**
 * open-design-landing-deck — input schema.
 *
 * Sister skill to `open-design-landing`. Produces a single-file slide
 * deck (horizontal swipe pagination, magazine-style) in the Atelier
 * Zero visual language, reusing the same `styles.css` + the same
 * 16-slot image library.
 *
 * The schema is intentionally smaller than the landing page schema:
 * a deck is an ordered array of typed slides, each driving one
 * viewport-height/width frame. Brand identity is shared across slides.
