/* Otian AI Consulting.
   Same family as otianai.com: its tokens, Georgia over Inter, the terracotta. Its own layout,
   because the job differs: that site sells software and ends on a download, this one sells two
   people and ends on a booked call. Left-aligned editorial headings, the people in the first
   screen, the reviews as a collection that grows, and the booking button in the header throughout.
   The color values are otianai.com's, copied (css/styles.css :root and [data-theme="dark"]);
   if the brand moves there, move it here. */
