Tencent/VasSonic ? reverse-engineered prompt

Build me a lightweight hybrid framework that makes web pages load their first screen much faster on Android and iOS.

I want it to work with pages that are partly static and partly dynamic, and to support cached offline resources too. The main idea should be that the app can request the HTML in a smarter way, start showing content early, and update only the parts that change instead of reloading everything. Please include the mobile client side pieces and the server side helpers so the whole flow works end to end.

It should come with a simple sample app and clear setup instructions for Android and iOS, plus at least one server example I can use to test the full experience. If you need to check current docs or platform details online, go ahead and do that. Keep it practical, easy to run, and focused on making web content feel much closer to a native app.
