/* ═══ Giriş akışı ortak stilleri (login.php + login_2fa.php) ═══
   4 Eki 2026: console.gamedev.ist giriş ekranıyla aynı aile (sol marka kanvası + sağ form).
   Değerler console styles.css "ca-" bloğundan uyarlandı; pay'e özgü farklar:
   - koyu temada küçük metin renkleri (etiket, bağlantı, bildirim) AA için açık tonlarda,
   - 2FA sayfasında sayaç ve kurtarma kodu bölümü (console'da yok).
   Yerel dosya (CSP 'self'). Tema: html[data-theme], gd_theme anahtarı panel ile ortak.
   Dolgulu buton iki temada #0272D6 + beyaz (4.8:1). */
