Studio header with a transparent full-width bar: logo on the left, inline links centred on desktop, a CTA and a Menu button on the right. After scrolling, the bar turns frosted, the logo shrinks and the links fold away; it can also hide on scroll down. The Menu button opens a full-screen curtain overlay with large numbered links, the current page marked by an accent dot, and social links, email and phone along the bottom. Desktop shows a photo preview on link hover; phones show thumbnails. Esc closes it; focus and page scroll are locked while open.
