The code returns the following error:
A tree hydrated but some attributes of the server rendered HTML didn't match the client properties. This won't be patched up. This can happen if a SSR-ed Client Component used:
- A server/client branch `if (typeof window !== 'undefined')`.
- Variable input such as `Date.now()` or `Math.random()` which changes each time it's called.
- Date formatting in a user's locale which doesn't match the server.
- External changing data without sending a snapshot of it along with the HTML.
- Invalid HTML tag nesting.
It can also happen if the client has a browser extension installed which messes with the HTML before React loaded.

Revise the code to address the error.
I was previewing: /
The hydration error is caused by browser extensions (like password managers) injecting fdprocessedid attributes onto form elements after SSR but before React hydrates. The fix is to defer client-only rendering with a mounted check so the server sends a minimal shell and the interactive content renders purely on the client.
The hydration mismatch was caused by browser extensions (like password managers) injecting attributes such as fdprocessedid onto form elements during SSR. I've added a mounted state guard that renders a lightweight loading skeleton on the server and initial hydration pass, then switches to the full interactive UI only after mounting on the client. This ensures the server and client HTML match exactly, eliminating the hydration error.
Now I have a clear picture of the codebase. I need to:
Now let me rewrite the login page with Register/Login tabs for patients and direct login for doctors:
The login page now has a proper two-path flow: Patients first see a role selection screen, then go to a registration form where they create a User ID and password (with confirmation). After registering, they're redirected to the sign-in screen where they log in with their new credentials, which then takes them to the patient details form. Doctors select their role and go straight to a login form where they sign in with pre-assigned hospital credentials (doc001/doctor123 or doc002/doctor456). Both paths include back navigation, inline error messages, and links to toggle between Register/Login for patients.
