Upstream Tessellate opens on a dark #header (centered <h1>, subtitle, scrolly Explore button), then four section.main blocks — #first (icon features), #second (copy + six-tile gallery), #third (featured image + three columns), #fourth (CTA actions) — before #footer with social icons and copyright. On this Dune port that shell lives in templates/default.tsx, with shared credit chrome in components/layout.tsx for inner pages, styled by vendored static/html5up/ CSS.

Compare side-by-side with html5up.net/tessellate:

• #first’s three feature cards spotlight Blog, Search, and Archives with live paths under each icon
• #second’s gallery tiles resolve to Blog, About, Search, Archives, Blog again, and the upstream Tessellate page — not decorative dead ends
• Scrolly buttons (#first, #second, #third, #fourth) should land on those section IDs at mobile width as well as desktop
• Footer copyright/credit stays visible whenever show_html5up_credit is on

Honest Dune deviations: upstream’s single-page marketing copy becomes fixture routes under /blog, /search, /archives, and /about; search is server-side /api/search, not a static filter; the contact-style fourth band has no mail backend. No dark mode — Tessellate upstream is one design; a Dune lift may land later as an enhancement, not as fidelity.
