annetrack/OwnNetworkingJournal ? reverse-engineered prompt

Build me a clean browser app for tracking my networking, with no fake sample people or demo data anywhere.

I want a simple place where I can save people I meet, log interactions with them, organize them into groups, and keep track of follow ups so I do not lose touch. Please make it feel like a real personal networking journal, with a straightforward interface that is easy to use on desktop. The app should be ready to connect to real authentication and Supabase for saving data, and it should leave room for OpenAI powered extraction and voice transcription later, since those are part of the real setup and should not be mocked.

Use the existing project files and make it deployable as a clean prototype on Vercel. If you need to check current docs for anything, feel free to look them up online. Keep it polished, minimal, and focused on helping me remember who I met, what we talked about, and what I should do next.
