Priority fixes for meo.pt

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 27 external scripts without async or defer.

   Why it matters: A plain <script src> in the head stops the browser from showing anything until that file has downloaded and run.

   What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.

   37% of Telecommunications & Internet peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

   CAA records limit who can issue certificates

   Observed: No CAA record was found for meo.pt, so any public certificate authority may issue for it.

   What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.

   15% of Telecommunications & Internet peers do this.

4. Priority 4 · Accelerate

   HTTP/3 advertised

   Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
