 * Renders a stacked multi-section node label (name, stereotype, description
 * lines) as pure SVG text, one `createText` call per section so each section
 * can be styled through its own CSS class.
 *
 * Drop-in for `labelHelper` on nodes carrying a `stereotype`: same element
 * structure and return contract. The wrap width is a soft limit - an
 * unbreakable word may exceed it, and the calling shape self-sizes from the
 * returned bounds.
