+**Accessibility is mandatory** — every feature MUST comply with WCAG 2.2 AA
+and all markup MUST use HTML5-valid elements/attributes (no obsolete
+presentational attributes; presentation lives in CSS). New pages, components
+and template changes must keep the a11y guards green:
+`tests/unit/html5-attributes.test.js`, `tests/unit/report-template-wcag.test.js`,
+`tests/unit/css-a11y.test.js`, `tests/unit/page-titles.test.js` — and add
+coverage there when introducing new markup patterns.

+### Accessibility (WCAG 2.2 AA)
+
+This application targets **WCAG 2.2 Level AA**. Dedicated guards cover selected requirements:
+`tests/unit/html5-attributes.test.js`, `tests/unit/report-template-wcag.test.js`, `tests/unit/css-a11y.test.js` and
+`tests/unit/page-titles.test.js` verify HTML5-valid markup (no obsolete presentational attributes), semantic heading
+hierarchy, table captions and scoped headers, chart alternative text, landmark names, color contrast, focus visibility,
+target sizes and per-page titles. Extend these tests when you introduce new markup patterns.
