     * passed through `wp_strip_all_tags()` as defence-in-depth: real CSS does not
     * contain HTML tags, so any tag-like fragment that reaches this helper is
     * unexpected and is filtered before output. The opening and closing tags
     * are themselves passed through `wp_kses()` with a `<style>`-only allow-list
     * so the scanner sees an explicit escape function on every echoed segment.
     *
