Different ways of browsing
The site uses semantic headings, a skip link, visible focus indicators, labeled controls, text-based comparisons and reduced-motion support. On a narrow screen, Menu opens the page list. Sign and Share stay along the bottom edge. Articles and the default comparison remain readable without JavaScript.
Using the explorer
Tab to the city, date and view controls, then activate Compare daylight. Results use a polite live region. Both morning and evening values have text labels. No meaning depends on color alone.
Sharing
Use Share this page for your device’s options, or Copy link. If clipboard access fails, a selectable URL appears.
Verification boundary
