Upstream Miniport pairs a fullbleed portrait with a headline, a short intro, and a single scrolly CTA, then drops into an icon-tile grid pointing at the rest of the site. On this Dune port that shell lives in templates/default.tsx, styled entirely by the vendored static/html5up/ CSS — this post exists so the demo explains what you're seeing instead of shipping a generic clone.

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

• The portrait + headline pairing (hero_image / home_headline) should feel like the same family as upstream's photo-led hero
• The four-box tile row below it (Blog, Search, Archives, About) stands in for upstream's project grid — icons come from a small rotation, not per-tile uploads
• Footer credit (#copyright) stays visible under article.wrapper.style4 whenever show_html5up_credit is on
• Active nav in the top bar highlights correctly at mobile widths, trailing-slash safe

Honest Dune deviations: upstream's per-project detail pages become ordinary blog posts under /blog; search is server-side /api/search, not a static filter; contact links have no mail backend behind them. No dark mode — Miniport upstream is one design; a Dune lift may land later as an enhancement, not as fidelity.
