What to fix
- No security.txt: publish one at /.well-known/security.txt with Contact and Expires lines (RFC 9116). Guide
- No HSTS header: browsers can still be downgraded to HTTP on the first visit.
- No accessibility statement link found on the homepage. Legal notices checklist
- No llms.txt: a short Markdown index of what the site offers to AI assistants. Guide
- No A2A agent card at /.well-known/agent-card.json. Guide
