/* ============================================================
   TitleStylePanel 标题样式面板 — 独立共用样式（#1809 ⑦）

   从 generate.css 抽取的标题样式区块，供「智能剪辑」与「AI数字人」
   两个页面共用。AI数字人页面不引入 generate.css，直接由
   TitleStylePanel.tsx import 本文件，保证 24 个 T 预设格子的网格布局、
   配色描边、选中态与智能剪辑页面完全一致。

   注意：本文件规则与 generate.css 中同名规则一一对应、取值相同；
   智能剪辑页面两处同时存在时同优先级同值，不改变其原有呈现。
