这是一个基于 HTML、Tailwind CSS 和 JavaScript 构建的纯前端二维码生成与解析工具，无需后端部署，打开即用。它主要具备以下特点：
-
核心功能：支持将文本或网址快速生成二维码，并可下载为高清图片；同时支持上传二维码图片，智能解析其中的内容。
-
技术亮点：采用 Tailwind CSS 实现响应式布局与玻璃拟态 UI，结合 AOS 和 GSAP 增强页面交互动效，通过调用免费 API 完成二维码的编解码。
-
适配体验：完美兼容移动端和桌面端，加载状态、错误提示等细节处理到位，交互体验流畅自然。
如果你想要其他风格（如更简洁、更营销化），也可以告诉我，我会帮你进一步调整。
