Upstream Ethereal scrolls as panels inside #page-wrapper > #wrapper. Home opens with section.panel.banner.right (major heading, tagline, circle Next action, filtered image), then a panel.spotlight carrying the page title, a panel.color1 with ul.grid-icons.three.connected, and another spotlight. There is no conventional top nav on landing — inner pages inject a panel.color1 action row for Home plus site nav. On this Dune port that shell lives across components/layout.tsx and templates/default.tsx, styled by the vendored static/html5up/ CSS (plus noscript.css when JS is off).

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

• The banner’s Next circle aims at /blog when a blog route exists
• The connected icon grid links Blog, Search, Archives, and About as real routes
• Spotlights use filtered/tinted images from the vendored set (pic02, pic03)
• .copyright stays visible whenever show_html5up_credit is on

Honest Dune deviations: upstream’s multi-page HTML becomes ordinary posts under /blog; search is server-side /api/search, not a client filter; Ethereal’s gallery/lightbox demo pages are not fully ported — the Dune demo uses panel spotlights and the icon grid instead. No dark mode — Ethereal upstream is one design; a Dune lift may land later as an enhancement, not as fidelity.
