/* ===========================================================================
 * Article-image figures (bin/mdbook-image preprocessor output)
 *
 * The preprocessor stamps the natural width/height of the shipping derivative
 * onto the <img> element so the browser can reserve layout space and avoid
 * cumulative layout shift (CLS). Without `height: auto` the HTML height
 * attribute is treated as a fixed pixel size, and `max-width: 100%` then
 * compresses the width below the natural ratio when the column is narrow —
 * producing a horizontally squished image. Setting `height: auto` lets the
 * browser scale the height proportionally and keep the aspect ratio.
 *
 * `display: block` removes the inline-baseline gap under the <img>; centering
 * via auto margins keeps the figure on the article column.
 * ========================================================================= */
