Builds a per-page WCAG 2.2 compliance score report by aggregating output from one or more accessibility scanners (axe-core / pa11y / lighthouse / WAVE / IBM Equal Access), pivoting violations by Success Criterion (1.4.3 contrast, 2.4.7 focus visible, etc.), grouping by conformance level (A / AA / AAA), reporting per-page coverage gaps explicitly (the "this page wasn't scanned" failure mode), and emitting both an executive summary and a per-page drill-down. Use after a multi-page accessibility scan - pa11y-ci, axe across a sitemap, lighthouse-batch - when the team needs a shareable conformance report rather than a per-page tool dump.
