/* ==========================================================================
   Compare chapter on purchase pages (sections/product-compare.njk, column swapping: assets/js/product-compare.js).
   Ported from the .pp-compare block of product-page.css on premierrobotic-compare, with the few .pp-* helpers it
   leans on (.pp-wrap, .pp-head, .pp-eyebrow, .pp-headline, .pp-intro, .pp-more, .pp-pill-link, .pp-visually-hidden)
   brought along, so the chapter looks the same on every sister site. Linked by base.njk on pages whose product is in
   src/_data/compareModels.json; not part of the purged, inlined foundation.css (like product-hero.css).
