/* ═══════════ FIELDSET / LEGEND (#1.4.61) ═══════════
 *
 * Tarayıcı varsayılan <fieldset> bir border çiziyor ve <legend>'ı bu
 * border'ın üzerine bindiriyordu — yazılar çizgilere yapışık görünüyor,
 * sıkışık duruyordu (Image 5, 6, 7).
 *
 * Çözüm: Border ve padding'i sıfırla. Fieldset semantik kalıyor (a11y
 * için önemli — radio gruplarını label'lar) ama görsel olarak normal
 * blok eleman gibi davranıyor. Legend ise .nde-step-label heading'i
 * gibi rahat görünüyor.
 *
 * `min-width:0` Flexbox/Grid içinde fieldset'in default min-width:
 * min-content davranışını ezer (uzun radio etiketleri taşmasın).
