+  自定义 HTML shell（替代 dx CLI 默认模板）。
+  存在的唯一原因：注入 favicon（<link rel="icon">），Dioxus.toml 的 [web.app]
+  没有提供 favicon 配置项。
+
+  注意：本文件复制自 dx CLI 生成的默认 shell（含 toast 基础设施 JS/CSS），
+  因此升级 dioxus-cli 后如 toast 行为有变，需重新从 `target/dx/.../index.html`
+  抓取默认模板并重新加上 favicon 链接。<title> 留空，由 [web.app] title 注入。
