   HERO ORBIT — shared hero artwork (About, Approach)
   The orb sitting in the horizon, flanked by industry chips. Extracted from
   css/about/about.css so more than one page can use it. Driven by
   js/hero-orbit.js. Load this AFTER the page stylesheet.
   `.ab-hero-art` is the historical About-page hook; `.hero-art` is the
   neutral one new pages should use.
