/* x13screendots — frontend overlay + custom zoom lightbox.
 *
 * Two render modes:
 *   .x13sd-overlay--compact: only dots, gentle pulse, clickable → opens zoom.
 *   .x13sd-overlay--full:    dots + leader line + label (inside zoom).
 *
 * Sizes for dot/line/label are computed in JS based on displayed image width,
 * so the whole overlay scales proportionally on small viewports and zoomed-in
 * lightbox. The CSS contains NO fixed-px dot dimensions on purpose.
