/* Home's "governed evidence" funnel graphic (SI_Logo_3D_v2.png + arrow
   shapes) is built from fixed-pixel absolute-positioned children (up to
   left:440px within a 520px box) authored for desktop. Those pixel offsets
   don't scale down with their container, so below ~620px viewport width
   this graphic pushes the whole page into horizontal scroll. It's purely
   decorative — the Grow/Defend/Control/Prove cards next to it carry the
   actual content and are unaffected — so hide it on narrow screens rather
   than risk a fragile rescale of hand-placed pixel coordinates. */
