/**
 * Clone SVG for export — async-friendly but with synchronous style capture.
 *
 * KEY CHANGES vs original:
 *  1. Computed styles are captured SYNCHRONOUSLY before any async frame splits.
 *     This prevents race conditions where DOM changes (modal close, scroll)
 *     corrupt styles in later RAF chunks.
 *  2. Caching is removed — each element gets fresh styles (fixes pie chart
 *     fill loss caused by cache key collision on same-class sibling elements).
 *  3. Async chunking is applied only to the WRITE phase (applying styles to clone),
 *     which is safe to defer as the data is already captured.
 *
 * @param {SVGElement} svg - ORIGINAL page SVG (not modal clone)
 * @returns {Promise<SVGElement>} The cloned SVG element
