Critical findings

No Content-Security-Policy. The browser will execute any script that ends up in the page, which is what turns an HTML injection into account takeover.Start with a report-only policy: default-src 'self'; object-src 'none'; base-uri 'self'.
No Strict-Transport-Security. A first visit over http, or any stripped link, can be intercepted before the redirect to https happens.Add: Strict-Transport-Security: max-age=31536000; includeSubDomains
