   PATCH WCAG AA:
   - --a11y-gray digelapkan: label seksi (#6b7280 pada #f4f6fb)
     hanya ~4.47:1, di bawah ambang 4.5:1 untuk teks kecil (1.4.3)
   - --a11y-focus baru untuk semua outline :focus-visible: gold asli
     (#d4a017) hanya ~2.38:1 di atas latar putih tombol, gagal
     ambang 3:1 untuk indikator UI non-teks (1.4.11). --a11y-gold
     asli tetap dipakai untuk elemen dekoratif (kbd, garis bantu
     baca) yang bukan indikator fokus.
