Build me a simple web app that lets people open exported WhatsApp chat files and read them in a clean, familiar chat view that looks like Messenger or WhatsApp.

I want users to be able to import a chat export, see the messages in conversation order, and easily follow who said what and when. Make the experience feel friendly and straightforward, with a nice chat style layout, avatars or names where useful, and a good way to browse long conversations without it feeling messy.

If it makes sense, include a way for users to save and share chats with an account, and use Google Drive as an optional storage option. Keep the app easy to run locally, and if you need current docs for anything, look them up online first.
