No H1 heading found
SEO
Add exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
Missing viewport meta tag
Accessibility
Add <meta name="viewport" content="width=device-width, initial-scale=1"> — without it the site is broken on mobile.
TLS certificate expires in 21 days

Missing X-Content-Type-Options header
