/**
 * Static export: the current view as a standalone SVG file or a PNG raster.
 *
 * The exported SVG must survive leaving the page, and on the page its
 * appearance comes from two different places: marks carry presentation
 * attributes (`fill` from the colour scale), while everything else is styled by
 * the injected stylesheet through classes and `--apexmaps-*` custom properties.
 * A serialized clone keeps the first and silently loses the second, which is
 * the classic broken map export: right shapes, wrong everything else.
 *
 * So the clone gets the *computed* style of every node inlined onto it, for a
 * whitelist of visual properties. Computed values have custom properties and
 * dark mode already resolved, so what leaves the page is what was on it, with
 * no second copy of the stylesheet to keep in sync.
 *
 * What this deliberately does not cover in P1: the legend and tooltips are
 * HTML outside the SVG, so the export is the map plot itself. Fonts are named,
 * not embedded; a viewer without the page's font falls back.
 *
 * @module export/Exporter
