Prompt
Build an accordion FAQ. Each row is a full-width button with the question in 16px medium weight on the left and a chevron on the right that rotates 180° when open. Top and bottom of each row has a 1px divider in the line color. Click expands the answer with a height + opacity transition over 240ms; answer is 14px in the muted text color, with comfortable line-height (1.55). Only one row open at a time (controlled).

Ease-out for entrance, ease-in-out for state. 200ms hover, 400–600ms layout. Stagger children at 30–60ms so groups feel intentional, not synchronized.
Spacing
Pick one scale (4 or 8) and don't mix. Section padding 96–128px desktop, 48–64px mobile. Headline sits ~24px above the subhead; subhead ~32px above the CTA cluster.
