Why this pattern works

Help users compare source syntax with the formatted result while keeping both in view.

Design notes

Surface: Markdown editor
Navigation: The product header and playground selector sit above the working panes.
Layout: Two tall panes place the formatted article on the left and Markdown on the right.
Density: Primary content has the most space; repeated rows and secondary navigation use a compact, consistent rhythm.
Color: Pale neutral surfaces, dark text, syntax colors, and a sample document image.
Type: Rendered headings and body text contrast with the source pane's monospace syntax.
Pattern: Help users compare source syntax with the formatted result while keeping both in view.
States: Public editor playground displaying its supplied starter document.
Don't: Adapt the interaction pattern to your own product. Do not copy brand assets, sample identities, proprietary text, or assume unseen states. Specify keyboard behavior, loading, empty, error, and narrow-screen layouts for your implementation.

## Objective
Adapt the interaction and layout patterns below to my project. Use my own content and identity. Do not reproduce logos, proprietary copy, or brand assets.

## 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.
