/*!
 * 雾寻图片工坊 · 插件版页面框架（对齐离线单文件版 · 蓝紫科技风）
 * ------------------------------------------------------------------
 * 设计基准 = 离线版 在线工具/index.html：
 *   · 径向渐变页面底（左上淡蓝紫 / 右上淡粉）+ 冷调蓝灰 --soft
 *   · 没有大 hero 卡片：一行紧凑「页头」（品牌 + 描述 左 / 控件 右）
 *   · 分节标题 + 右侧发丝线
 *   · 白卡片 · hairline 蓝调边框 #e7ebf9 · 16px 圆角 · 极轻阴影
 *   · 唯一强调 = 蓝紫渐变 #4f6bff → #a56bff
 * 只负责：设计变量、顶栏、页头、分节标题、容器、按钮、表单件、图标、底栏。
 * 各页特有样式留在 library.css / ai.css。
 * 注意：不要写无作用域的 main / body 规则，避免污染前台页布局。
