RydzzKen/swiss-editorial-minimalist ? reverse-engineered prompt

Read the SKILL.md file I attached and build me a clean Swiss editorial style website for a small AI design studio called Northline.

I want it to feel monochrome, calm, and premium, not like a typical startup landing page. Use a simple editorial layout with a strong hero, a short services section, a selected work section, and a contact or call to action area. Make the typography feel deliberate, the spacing airy, and the whole page very restrained.

Please keep it in one complete HTML file with inline CSS and JavaScript, and make sure it works well on mobile and desktop. Add a dark mode toggle that actually works, and use simple line based visuals or icons instead of colorful illustrations. No gradients, no heavy shadows, no big rounded cards, and no bright accent colors.

If anything in the skill has a fixed style choice, follow that automatically.
