🟒a11y_check_url(url, max_violations, refresh)

Run an automated accessibility check (axe-core + Lighthouse) on ONE public http(s) web page and return a score, badge tier, and the most important violations with CSS selectors so you can suggest fixes. Takes up to ~1–2 minutes. Automated checks cannot prove WCAG conformance: 'no automated errors found' still needs manual review. Only public pages are accepted (private/localhost addresses are rejected). (곡개 μ›Ή νŽ˜μ΄μ§€ 1개 μžλ™ μ ‘κ·Όμ„± 검사. μžλ™ κ²€μ‚¬λŠ” μ€€μˆ˜λ₯Ό 증λͺ…ν•˜μ§€ λͺ»ν•˜λ©° μˆ˜λ™ 확인이 λ‚¨μŒ.)
