EarthyFox/GFTP ? reverse-engineered prompt

Build me a full stack tea journaling app for Gong Fu Cha lovers.

I want users to be able to sign up, log in, and keep their own private data. The app should let them record tea sessions with things like steep time, water temperature, leaf to water ratio, tasting notes, and a flavor profile. It should also have a tea stash area where they can track the teas they own, including tea type, source, and any notes.

Please include a few simple brewing tools, like ratio and unit conversion helpers, and add preferences so each user can choose their unit system for things like temperature and volume. Make it feel clean and easy to use on desktop and mobile.

Use the existing project setup and make it work as a deployment ready web app. If you need current docs or deployment details, look them up online and follow the usual best practices.
