/**
 * Pysäkkilinja (stop line with one panel at a time)
 * A horizontal line of numbered stops; the active stop's panel shows below. Used on the
 * Index front page section "Miten autamme sinua?" (direction B). Structure:
 *   .gb-container.pysakkilinja            (chain-animated; stops stagger in via CSS delays)
 *     .gb-container.linja-pysakki[.is-active]  p.linja-marker + p.linja-nimi
 *   .gb-container.linja-paneelit           (next sibling of the line)
 *     .gb-container.linja-paneeli[.is-active]
 * js/blocks/pysakkilinja.js turns the stops into a tablist and switches panels. Without JS
 * (and in the editor) every panel is visible, stacked.
