     * `querySelectorAll('[data-icon]')` sweep (see `repaintIcons`) rather than a
     * teardown and rebuild of every subsystem that ever drew one.
     *
     * `width`/`height`/`style` are injected ahead of anything the source markup
     * carries. The HTML parser keeps the *first* of a duplicate attribute, so
     * these win — which is why icon sets must not declare their own.
     *
     * @param name - Registry name. Returns `''` when unresolved, so a missing
     *   icon collapses to nothing rather than throwing.
     * @param size - Edge length in px.
