Why this pattern works

Keep model selection visible when comparing chat experiences.

Design notes

Surface: A comparison-ready chat workspace exposes model selection, a conversation sidebar and a broad prompt composer.
Navigation: Left conversation sidebar and top model controls
Layout: Large empty conversation canvas with composer below
Density: Comfortable spacing with focused controls.
Color: White, light gray and violet
Type: Readable sans-serif controls and clear heading hierarchy.
Pattern: Keep model selection visible when comparing chat experiences.
States: Public initial state; no user content submitted.
Don't: Adapt the layout to your own product and supported capabilities; write your own examples and keep important actions clearly labeled.

## Acceptance criteria
- Existing project conventions, design tokens, working functionality, and unrelated changes are preserved.
- Two or three reference principles clearly support the user's task; conflicts are resolved in favor of usability and the existing product.
- Reusable components and semantic HTML express the interface. Available licensed assets are used; important UI text is never rendered as a bitmap.
- Every visible control has a defined behavior. Loading, empty, error, success, disabled, and long-content states are specified where relevant. Demo data is clearly labeled.
- Navigation and content adapt at 375px, 768px, and 1440px without horizontal page overflow. Keyboard use, visible focus, labeled inputs, at least 44px touch targets, readable contrast, and reduced motion are supported.
- Verification distinguishes rendered behavior from proposals and identifies anything still requiring a backend or external service.

## Quality bar
Clear hierarchy, consistent spacing, restrained surfaces, and purposeful motion. Avoid decorative gradients, excessive cards, placeholder buttons, and invented metrics unless the project calls for them. Do not claim a feature is connected or tested without evidence.
