/* Animated building blocks for blog articles.
 *
 * Post bodies pass through HTMLPurifier on save, which strips <style>, <svg>,
 * data-* attributes and animation CSS. Everything here is therefore driven by
 * plain class names (and an inline width on chart bars, which the purifier
 * keeps), so authors can write ordinary <div class="sx-..."> markup.
 *
 * Elements start in their final state; the reveal script adds .sx-js to the
 * body first, so if JS never runs nothing is left hidden.
