audit_htmlAudit an HTML string for accessibility violations. Ensures a debuggable Chrome (auto-launches one headless if none is reachable), loads the HTML into a blank tab, and runs the @accesslint/core engine against the real DOM. Auto-detects fragments vs full documents.

audit_liveAudit a live URL via CDP. Ensures a debuggable Chrome (auto-launches one headless via @accesslint/chrome if none is reachable — no manual setup needed), then runs the @accesslint/core engine against the live DOM. CSP-bypassing. Use this for any URL audit.
