/**
 * Homepage "Our Services" band — hover-expanding accordion.
 *
 * A full-bleed navy section under the milestones: a skyline strip on top,
 * a centered title/description, then a horizontal accordion whose panels
 * share the width until one is hovered/focused — that panel expands while
 * the others contract (flex). On touch the same band becomes a sideways
 * scroll-snap swipe strip (each slide ~84% wide, a peek of the next one).
 *
 * Approved from prototype/service-slider.html and scoped to the theme brand
 * palette (--sfm-navy / --sfm-green / --sfm-font-sans).
