Quick Wins

High-impact, low-effort fixes, ranked by what this scan actually found.

Mute the autoplaying media or give it controls — Nothing starts making noise the visitor cannot stop.
Load the first image eagerly — The largest image starts downloading with the page instead of after it.
Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
Point the aria-* attributes at ids that exist — The controls announce the name the markup was already trying to give them.
Serve the intermediate certificate with the leaf — The certificate validates on every client, not only the ones that have seen the intermediate before.
Close menus and dialogs on Escape — Keyboard users can close the menu or dialog the expected way.

What the site checks found

Medium — Security — The server sends no intermediate certificate, so clients that have not cached it refuse the connection.
Low — Security — No CAA record — any certificate authority may issue a certificate for this domain.
Low — Security — The zone is not signed with DNSSEC, so a forged DNS answer cannot be detected.
Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
Low — Performance — The HTML is compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
