Subject: [PATCH] Improve accessibility for CAPTCHA challenges in DeepSeek v3
Add accessible CAPTCHA solution using hCaptcha to improve accessibility for visually impaired users.
* **Add dependencies**: Add `hcaptcha` and `flask` to `requirements.txt`.
* **Implement hCaptcha in Flask app**: Create `app.py` to set up Flask application, configure hCaptcha, and create routes for sign-up and login with hCaptcha integration.
* **Create sign-up form**: Add `templates/signup.html` with HTML form for user sign-up, integrating hCaptcha widget and adding ARIA labels and roles for screen reader compatibility.
* **Create login form**: Add `templates/login.html` with HTML form for user login, integrating hCaptcha widget and adding ARIA labels and roles for screen reader compatibility.
* **Add CSS styles**: Add `static/css/styles.css` to style form elements and hCaptcha widget, ensuring high contrast and readability for visually impaired users.
* **Write unit tests**: Add `tests/test_accessibility.py` to test accessibility features using NVDA and verify hCaptcha integration and screen reader compatibility.
