/**
 * Gets the effective CSS zoom factor applied to an element or any of its ancestors.

 * On mobile, the parent application may apply CSS zoom to accommodate device font
 * size settings. This zoom affects coordinate calculations for click/touch events,
 * as both clientX/clientY and getBoundingClientRect() return zoomed values, but
 * the SVG coordinate system expects unzoomed pixel values.
 *
 * Note: We calculate the cumulative zoom by traversing the DOM tree rather than
 * targeting specific elements to avoid coupling Perseus to parent application
 * implementation details (e.g., specific class names or DOM hierarchy).
 *
 * @param element - The DOM element to check for CSS zoom
 * @returns The cumulative zoom factor (e.g., 1.5 for 150% zoom, 1.0 for no zoom)
