<h2>🧪 How to Test</h2>
<ol>
<li><strong>Start the servers:</strong>
<br><code>python app.py</code> (Backend on port 7060)
<br><code>python run_frontend.py</code> (Frontend on port 8000)
</li>
<li><strong>Open registration form:</strong> <code>https://prodevroger-ishingiro.hf.space/register</code></li>
<li><strong>Test field-specific errors:</strong>
<ul>
<li>Try submitting with empty fields</li>
<li>Try invalid email formats</li>
<li>Try invalid phone numbers</li>
<li>Try weak passwords</li>
<li>Try registering with existing username/email/phone</li>
</ul>
</li>
<li><strong>Verify:</strong> Each field shows its specific error message below the field</li>
</ol>
</div>
<div class="test-section">
<h2>📱 Visual Error Display</h2>
<p>Errors now appear:</p>
<ul>
<li><strong>Below each field</strong> with specific error message</li>
<li><strong>With red border</strong> around invalid fields</li>
<li><strong>With green border</strong> around valid fields</li>
<li><strong>Real-time validation</strong> as user types or leaves fields</li>
<li><strong>No generic error banner</strong> at the top of the form</li>
</ul>
</div>
<div class="test-section">
<h2>🎯 Benefits</h2>
<ul>
