 * every keystroke in the editor.
 *
 * Never shown when: empty code (same "no code given" check as
 * generateElement), or an error is present (a resolved outcome — the error
 * needs to be readable, not covered by a spinner).
 *
 * Visually matches Radix UI's <Spinner> (used as rx.spinner() in the Reflex
 * consumer apps): 8 bars radiating from center, rotated 45deg apart, each
 * fading out in sequence.
