WCAG AUDIT (POWERED BY AXE-CORE)
Run a scan on any page and get a score 0–100, per-violation report with the relevant WCAG success criterion and a Deque University deep-link.
• Default scan is fast and single-state — runs in whatever emulation you currently have applied. Opt in to multi-state to compare findings across default / dark / deuteranopia / reduced-motion / high-contrast.
• Element picker — click a component, scan only that subtree.
• Export as JSON, self-contained HTML (opens in a new tab), or GitHub-ready Markdown.
Inspect the latest comments and rating distribution.
