/**
 * Data-driven shape dispatcher for the drawio SVG preview (GH-481).
 *
 * Pure (no React, no DOM): given a cell's parsed style + absolute box, returns a
 * list of SVG primitive descriptors plus the text-inset box for the label. The
 * renderer maps each descriptor to a JSX element. Keyed on `style.shape` and the
 * boolean style flags drawio emits (`rounded`, `rhombus`, `ellipse`, …); unknown
 * shapes fall back to a plain rect so rendering is always graceful.
