Why this pattern works

Pair a code pane with a live preview and contextual export actions.

Design notes

Surface: Live editor
Navigation: Sample diagrams and action groups sit below the source editor.
Layout: Code and configuration on the left; the rendered diagram occupies the right.
Density: Keep the working area large; use compact labels for controls without shrinking the editing text.
Color: White canvas, pale violet diagram nodes, and dark connectors.
Type: Monospaced code contrasts with compact sans-serif interface labels.
Pattern: Pair a code pane with a live preview and contextual export actions.
States: The default sample flowchart, with the optional promotion dismissed.
Don't: Do not copy brand assets or sample records. Preserve keyboard access and design empty, loading, and error states for the actual task.

## 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.
