   - 加载逻辑：persona 数据从「点击 persona tab 时才加载」改为「info tab 首屏即加载」（`if (tab==='info' && persona===null) await loadPersona()`，与视频数据并行 dvP/await 拆分）；tab 点击处理器去掉冗余 persona 加载
 - **验证**：bindPager/bindBatchBar 均用 querySelectorAll/空值守卫，容器缺元素不报错；data-rewrite（AI创作）点击时仍 `if (!persona) await loadPersona()` 兜底；data-extract 绑定全局查找在 info tab 同样生效
