Build me a full stack app for creating branded short links and personal bio pages. I want users to be able to sign up, log in, verify their email, reset their password, and stay signed in securely. After login, they should get a dashboard where they can paste in a long link, make a short link with either a random 6 character code or a custom alias, copy it easily, delete it, and download a QR code for it.

I also want a public bio profile page for each user at /bio/:username where they can upload an avatar, write a short bio, add social links, and pick from a few different themes. The short link side should track clicks, referrers, and device type, and show simple analytics charts for that data. Make the whole thing feel polished and modern with a dark linear style, subtle glow, smooth interactions, and responsive layouts. Use current docs online if you need to.
