parth-access/saarthi ? reverse-engineered prompt

Build me a simple, warm web app called Saarthi, a safe space where people can sign in, save their thoughts, and feel supported while using it.

I want the app to feel calm and reassuring, with a clean home screen, a place to write private entries or messages, and some kind of personal dashboard so users can come back to what they saved. If it makes sense, include basic account handling and keep the data secure, since this is meant to feel private.

Please make it polished and ready to run, and wire up the backend so user data actually persists. If you need to check current docs for anything, feel free to look them up online.
