<ul class="text-blue-200 text-sm space-y-1">
|
||||
<li>✅ <strong>Top section:</strong> SSR - Query ran on server before HTML sent (instant load)</li>
|
||||
<li>✅ <strong>Bottom section:</strong> React component using <code>/api/shim/sites/list</code></li>
|
||||
<li>✅ <strong>Security:</strong> Database credentials never exposed to browser</li>
|
||||
<li>✅ <strong>Performance:</strong> SSR = ~10ms, API = ~50ms (includes HTTP overhead)</li>
