/**
 * Ekomateriály page — design layer.
 *
 * Reproduces design/ekomaterialy.html 1:1: lead paragraph, sticky anchor nav +
 * content card, eco callout, the two-column comparison, the material blocks
 * (optional image, alternating side), the teal CTA band and the feature strip.
 * Everything is scoped under .eko so the generic names (.cmp, .tag, .mat-*)
 * never leak into other pages.
 *
 * Anchor/sticky offsets use var(--anchor-offset) rather than the mockup's 96px:
 * the mockup's header is 60px tall, the real theme header is 88px (image logo).
