 * Re-renders every registry-drawn icon under `roots` from the renderer's current

 *
 * This is what makes a theme's icon pack swappable at runtime. Icons are drawn
 * once when their DOM node is built and are not rebuilt by `GridApi.refresh()`
 * — the header, footer, toolbar, launchers and toast layer are all long-lived —
 * so without this sweep a pack change would only reach rows that happened to be
 * re-rendered.
 *
 * **Host-supplied icons are left alone, by construction.** `data-icon` is only
 * ever written by {@link IconRenderer}, so raw markup or elements a host passed
 * through `RowMenuIcon`, a dropdown option or a custom header renderer carry no
 * marker and are invisible here. No allowlist is needed.
 *
 * Two node shapes exist and are handled differently:
 * - a marked `<svg>` — produced by `renderToString`; the node *is* the glyph, so
 *   it is replaced outright.
 * - a marked container — produced by `render()`/`updateIcon()`; its contents are
 *   refilled in place, preserving the wrapper's classes and inline sizing.
