 * The Boss Voice Section Player: small voice button.
 *
 * Every visual value comes from CSS custom properties (--tbvsp-*) that the
 * Design Customizer writes (see TBVSP_Design::vars). The fallbacks below are the
 * default Minimal Circle design, so the button looks right even without them.
 * All selectors start with .tbvsp: nothing outside the component is touched.
