Fractal's config surface is all first-viewport: everything it exposes shows up in the phone-mockup hero on /, not buried in a settings page.

header_title

This demo sets “Fractal” via demo-config.json, rendered as the h1 next to the phone mockup. Empty falls back to the site title — fine for a real site, but the demo names the theme explicitly so the hero always matches what you're evaluating.

header_subtitle

Set to “A phone-first portfolio for Dune demos”, the <p> under the title. Falls back to the site description when empty; a blank subtitle next to a phone mockup reads as unfinished, since upstream Fractal always pairs the two.

phone_image

Pointed at the vendored static/html5up/images/screen.jpg — the same placeholder screenshot upstream Fractal ships inside the device frame. A real site would swap this for an actual screenshot of the product or app being showcased; leaving it empty falls back to this same file, so the demo makes that default explicit rather than implicit.

show_html5up_credit

On. Gates the visible HTML5 UP credit in the footer, required under CC BY when the toggle is on. Turn it off only with a separate Pixelarity license — it should hide every credit surface together.

footer_text

Set to “Fractal Demo” so the copyright line reads as a demo, not a site borrowing its own long title.

No dark mode here — upstream Fractal is one design; a Dune lift would be a future enhancement, not fidelity work.
