QA: Chat Customization (CSS) — Spring AI

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy (check /api/health)

Test Steps

• Navigate to /demos/chat-customization-css
• Verify the chat renders inside the scoped .chat-css-demo-scope wrapper
• Verify user messages have the hot-pink gradient bubble style
• Verify assistant messages have the amber boxy monospace style
• Send a message and verify both bubble styles render correctly

Expected Results

• Chat loads within 3 seconds
• Themed styles only apply inside the demo scope (no global leak)
