Mirror the reference theme's universal picker on FA5: a generated full catalog of the bundled FA5 Free 5.15.4 fonts (src/Icons/fa5-icons.php, generated from the shipped CSS + SVG fonts), a zibsvg group parsed from the runtime sprite so it cannot drift, and GET /aksrt/v1/icons/catalog. Shared admin pieces: aksrt_icon_markup()/aksrt_sanitize_icon_value() with an SVG allowlist, the picker field/modal assets, and one canonical aksrt-font-awesome handle registered through aksrt_enqueue_fontawesome().
