/**
 * DeskPicko Editorial Engine — Comparison Engine frontend.
 *
 * Namespace: `dp2-comparison-`, isolated from every other dp2- module
 * (no bare .card/.button/.table/.badge anywhere in this file — every
 * selector here is prefixed, same discipline as dp2-product-reveal.css).
 * This file defines its own --dp2cmp-* custom properties rather than
 * reusing dp2-product-reveal.css's --dp2pr-* ones — same palette
 * values, but no cross-file dependency between the two components.
 *
 * Visual language matches the approved blueprint: white surface, dark
 * ink typography, one restrained blue accent, light gray dividers, a
 * green accent reserved specifically for the verdict box and winner
 * treatment, generous spacing — premium editorial, not ecommerce-loud.
 *
 * RESPONSIVE STRUCTURE — mobile-first, single 641px+ breakpoint, same
 * convention dp2-product-reveal.css already uses for its own
 * desktop/mobile split. Below 641px, product cards stack, and the
 * collapsible sections are real <details> elements a reader can open/
 * close by hand. At 641px+, product cards sit side-by-side and every
 * <details> is forced open (and locked open by
 * assets/js/dp2-comparison.js, a small enhancement — see that file)
 * so desktop never hides content behind a click, per the approved
 * blueprint's explicit requirement.
