Top issues to fix

Missing Content-Security-Policy header
Security
Add a CSP to control which sources can run scripts — the strongest single defense against XSS.
No H1 heading found

Add exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
Meta description longer than 160 characters
SEO
Trim the meta description to under 160 characters to avoid truncation in search results.
2 broken links on the page
