/* ==========================================================================
   Agency comparison — components/marketing/AgencyCompare.tsx.

   Loaded per page through ServicePageData.extraStyles on the web-design
   pages. The section header uses offer.css (.ofr__eyebrow, .ofr__h2,
   .ofr__lead), which ServicePage always loads; this sheet owns the rows.

   NAMESPACE. `acm-`. The palette is declared here with fallbacks rather than
   inherited from .svcd-section, because /architected-websites/ does not load
   service-devices.css and the section has to look the same everywhere.

   THE TWO COLUMNS follow the site's rule (service-devices.css, .svcd-panel):
   a dashed border means the old way, a lit purple panel means ours.

   MOTION CONTRACT. Everything ships finished. From-states live only behind
   html.has-motion, which motion.js adds solely under
   prefers-reduced-motion: no-preference. .is-in is set on [data-stage] by
   motion.js, with an IntersectionObserver fallback in offer.js.
