+  D-10（docs/20）搜索浮层 · 通用 fragment：theme.json 参数 searchStyle 控制门户搜索形态——
+  · inline（缺省）= 保留主题 header 自有内联搜索表单（现状外观，零变化）
+  · none          = 不渲染任何搜索入口
+  · overlay       = 隐藏内联表单，渲染右上「放大镜」按钮 + 全屏搜索浮层（本文件实现）
+  引用方式：主题 header.html 在其内联搜索表单位置——
+    <th:block th:if="${themeParams != null and themeParams['searchStyle'] == 'overlay'}"
+              th:replace="~{'themes/common/fragments/search' :: overlay(${url})}" />
+    <form class="…" th:unless="${themeParams != null and themeParams['searchStyle'] == 'overlay'}" …>（inline/缺省保留原表单）
+  样式/脚本自持（不引外部依赖）；颜色跟随主题变量缺省蓝。
