Deck-as-Page at /thesis — Full 17-Slide Teaser Composed from Narratives, DESIGN.md, and Reference Implementation

The whole deck rendered as a single scrollable page with section-per-slide scroll-snap, design tokens flowing from DESIGN.md into a real theme.css, and 17 section components composed from the upstream narratives. Same content, same brand, dramatically better visual outcome on the first build — directly attributable to the foundation work shipped the day before.
