CHINA TOP CABLE — Theme Custom CSS（Porto css-code）
工业硬朗 Industrial ｜ 批次 B（2026-09-28）
--------------------------------------------------------------------------
替换对象：原「科技蓝」版（页脚 #0e2a4e / 首页 #1668ff）
回滚：fixbackups/ctc-b2-*/ 里的 porto_settings.json，或 /root/ctc-csscode-backup-*.css
WCAG AA：#ff6a13 不做实心底/白底文字（2.87:1）→ 白底文字用 #c74a00（4.76:1）；
实心 CTA 一律 #c74a00 + 白字（4.76:1），hover #a83e00（6.26:1）；
页脚深底用 #ff6a13（5.99:1）。亮橙只做装饰（描边/图标/角标）
2026-09-29：实心 CTA 由「#ff6a13 + 深字」统一为「#c74a00 + 白字」，
与 porto-child/ctc-industrial-porto.css 的分工保持一致。
