Current implementation
Pages use semantic headings, a skip link, keyboard-operable navigation and filtering controls, labeled search and reduced-motion settings. The archive atlas has a text-based location list and direct map links in addition to its SVG locator.
Known constraints
The SVG atlas is a contextual visualization, not a replacement for the accessible text list. Complex comparison tools also provide explanatory text and linked sources. Full assistive-technology and cross-browser audits remain ongoing.
Report a barrier
Identify the affected page, device or browser, assistive technology if relevant, and the task that failed. The owner can prioritize a specific reproducible issue.
