Slide archetypes land in the corpus — a vocabulary for the narratives every pitch deck reaches for

27 canonical slide types — problem, why-now, fund-thesis, lighthouse-customers, blue-ocean-strategy — each with the names they go by in the wild, the tags they belong to, and a soft sequencing graph. The first layer of a deck-scheming substrate that lets DidiDecks recognize a slide by its purpose, no matter what the original deck called it.
