Upstream Paradigm Shift's home route is a full-height section.intro (banner_title, tagline, an arrow-scroll cue into #first) followed by six plain <section> blocks: a content panel that echoes the page title, an explore panel with icon links to Blog/Search/Archives/About, a four-image gallery, a get-started CTA, and a closing "Get in touch" section carrying the CC BY credit and a small items/icons footer with Dune and HTML5 UP links. Inner pages skip the whole stack for a single header/content section wrapped by a dune-nav button row, since upstream's original nav doesn't survive the section-scroll layout once you're off /.

Compare against html5up.net/paradigm-shift:

• The arrow-scroll cue from .intro to #first should land exactly on the next section, not overshoot
• The dune-nav button row on inner pages is a Dune addition — upstream has no equivalent since its nav lives inside the single-page scroll
• The CC BY credit appears twice (get-in-touch section and footer copyright) — both should hide together when show_html5up_credit is off

Honest deviations: multi-page HTML becomes Dune fixtures; search is server-side /api/search; no dark mode — one upstream design.
