/* On narrow screens (iPhone, home-screen Web App), give each section
   its own slot in a flex column so:
     - The orb is vertically centered in the hero area (flex:1)
     - The transcript has a bounded, scrollable area below
     - The chat form pins to the bottom over the safe-area inset
   Body is flex row + justify-content:center by default, which
   content-sizes its children along the horizontal axis even with
   width:100%. Flip body to column on mobile so the cross axis is
   horizontal and align-items:stretch genuinely fills 100vw.
   Use 100dvh (dynamic viewport height) so the layout adapts when
   the iOS keyboard opens and the viewport shrinks. */
