avn2312/langbridge ? reverse-engineered prompt

Build me a web app called LangBridge for language learners to find practice partners, chat in real time, and get help with translations and corrections.

I want people to be able to sign up with email, verify their account, or use Google sign in, then set up a profile with the languages they speak and want to learn, their level, timezone, location, interests, and a short bio. After that, they should be able to browse and match with other users, see why someone is a good match, send friend requests, block people, and report bad behavior.

The chat should feel instant, with typing indicators, read receipts, offline messages, attachments, voice notes, and call signaling if possible. Add simple tools for translating text, fixing drafts, saving useful phrases, and tracking learning activity in a dashboard. Please make it polished and responsive, with a React frontend and a Node backend, and use current docs online if you need to fill in any details.
