/*
 * /articles/
 *
 * 1. The base rules are a complete static page (no JS, or reduced motion):
 *    a short intro, then each category with a plain grid of articles.
 * 2. Rules under `.sn-js` apply only when the head script decided motion is
 *    welcome. They lift every article onto a single S-shaped track that
 *    scrolls like a snake. If the script never reports in, `.sn-js` is removed
 *    and the static layout returns.
 *
 * Only transform and opacity are animated.
