Pitch Deck — guided build

Take the user from nothing to a deployed, responsive pitch-deck site. Mirrors the brandbook-builder plugin pattern (brief → build → QA/deploy) but the deliverable is a section-scroll deck app, not a brand book.

The output stack is fixed: Vite + React + TypeScript + Tailwind CSS + motion (Framer Motion). The structural pattern is the utopia-os-deck section-scroll model (one component per slide, AnimatePresence loader, fixed Navbar, scroll-snap optional, motion reveals on enter).
