Security
Add a CSP to control which sources can run scripts — the strongest single defense against XSS.

Add alt attributes to images — screen readers depend on them, and they help image SEO.
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 15 days
Security
Renew soon or enable auto-renewal to avoid a browser-warning outage.
2 cookies without Secure/HttpOnly flags
