   GEXI — Step-by-step guide (idea to content, automate at any step)

   A page layer on the shared design system (brand tokens from styles.css + the
   gx-ui kit). Same Gemini-grade, GEXI-green look and dark mode as the homepage and
   Create. Mobile-correctness contract (the inherited overflow bug, fixed at the
   root): body is a flex COLUMN, so any max-width container that is a flex child also
   sets width:100% and min-width:0, and every horizontal strip is a bounded,
   swipeable scroll region. (Never place the comment-close sequence inside a comment.)
