Grouped
A two column FAQ split by topic: each group has a small heading over its own hairline list, next to the heading and contact line.
Interaction Type
A labelled section landmark. Questions sit in a flat list divided by hairlines; each is a heading with a button. Enter or Space opens it, its answer unfolds and the chevron turns. One answer stays open at a time and can be closed again. Reduced motion opens answers without the unfold.
