/**
 * RPA Digital Headquarters 0.20.0 (D34): the homepage's "Life in the Bond" photo mosaic,
 * "Meet the Brothers" spotlight rail and "Our legacy" milestones (views/public/home/gallery.php,
 * brothers.php, legacy.php). Loaded on the plugin homepage only, after public.css (whose size
 * budget it would break). The bands themselves (.rpa-band--night, --white, --crimson: colours,
 * padding, link and focus colours) and the head row (.rpahq-join__head) are shared; these
 * rules lay out what's inside. minmax(0, 1fr) and the rail's own scrolling keep a 390px page
 * free of sideways scroll; motion only without prefers-reduced-motion.
