Missing meta description

No H1 heading found
SEOAdd exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
1 cookie without Secure/HttpOnly flags

Missing canonical link
SEOAdd <link rel="canonical"> so search engines know which URL variant to index.
No structured data (JSON-LD) found
