/* ═══════════════════════════════════════════════════════
   hub.css — /boeken and /tto-boeken hub pages (v4)
   Depends on style.css (tokens) and methode.css (hero-gradient,
   methode-section, badge, tag, faq__list, text-shield, btn--*)

   Concept: a simple, beautiful product overview in a premium
   publisher register. One loud fan in the hero, four quiet
   mini-fans in the rows. Strict mirrored 12-column geometry
   for the alternating rows, hairline separators, typography
   and the covers doing the work.

   Motion register: entrance fan-out on the hero (same easing
   family as the overview pages' .book-fan), idle float on the
   hero covers, marker-swipe on the trust line (pure CSS, like
   the homepage's nh-mark), mini-fans spreading on hover, and
   a transform-only translate-up reveal on scroll (js/hub.js).
   Content never depends on JS; reduced motion turns it all off.
