Observatory log
Accessibility
The observatory interface is decorative on the surface and conventional underneath: every orbital element is a semantic list, link or heading.
Implemented
- Skip link, semantic landmarks and one logical H1 per page.
- Keyboard-operable navigation, search, consent controls and disclosures with visible focus.
- Orbital and constellation modules render as ordered or unordered lists in the DOM, in reading order.
- Status is never conveyed by colour alone; every evidence state carries a text label.
- 44px minimum touch targets, no horizontal scrolling at 390px, usable at 200% zoom.
- Reduced-motion preference removes transitions rather than shortening them.
