Why this pattern works

Use prompt suggestions to explain the breadth of an otherwise empty conversation.

Design notes

Surface: A sparse model-comparison chat start centers a composer beneath an editorial headline.
Navigation: Small left tool rail and mode selector.
Layout: Centered composer and example prompt chips in open space.
Density: Low-medium
Color: Warm white, black and yellow
Type: Serif headline with compact sans-serif controls.
Pattern: Use prompt suggestions to explain the breadth of an otherwise empty conversation.
States: Public empty chat composer; no prompt 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.
