/* Article Slider — front end
 *
 * The height is a CSS variable on .artsl and nothing else touches it: no
 * inline height written by JS, no transform: scale(), no fixed canvas. The
 * viewport is a plain block with overflow hidden and every slide is absolutely
 * positioned inside it, so the layout is identical in LTR and RTL and cannot
 * drift while the theme is still laying out the column.
