Keyboard navigation.
A skip link at the start of each page moves to the main content. Navigation links, menus, scenario controls, and expandable answers are keyboard accessible. Focus indicators identify the active control. The mobile menu can be closed with Escape, and the navigation dropdown uses a native disclosure element.
Motion preferences.
The site respects the browser’s reduced-motion preference. A Pause motion control in the footer stops the decorative topic scrollers and animated brand gradients for the current page. Hovering over a topic scroller also pauses its animation. No information depends on motion alone.
Readable structure.
Pages use one main heading, descriptive section headings, breadcrumb navigation, and meaningful link labels. Journal articles include a table of contents and text-based conclusions. Full-size featured images are accompanied by alternative text, and decorative interface icons are hidden from assistive technology.
Without JavaScript.
The guides, articles, navigation links, and native expandable answers remain available without JavaScript. The three architecture scenarios are shown together instead of requiring a selection. The copy interaction needs JavaScript; the example text can still be selected and copied manually.
