 * AutoPix front-end styles.

 * Sizing model: every figure gets two inline custom properties
 *   --apx-w : the width we WANT (percentage of the content column)
 *   --apx-r : the displayed aspect ratio (width / height)
 * and the width actually used is  min(wanted, maxHeight * ratio).
 * That single rule keeps tall portrait photos from ever exceeding the max height,
 * while landscape photos use the full wanted width. Works in any theme column width.
