Priority fixes for prisma.fi

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 1 external script 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.

   On Next.js: Use the next/script component with an appropriate loading strategy.

   44% of E-Commerce & Marketplaces peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

2. Priority 2 · Accelerate

   HTTP/3 advertised

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

   What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.

   47% of E-Commerce & Marketplaces peers do this.

3. Priority 3 · Enable

4. Priority 4 · Harden

   DNSSEC signed

   Observed: No DS record was found for prisma.fi at its parent zone, so its DNS answers are not DNSSEC-signed.

   What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.

   On Amazon Route 53: Enable DNSSEC signing for the hosted zone and establish the chain of trust at the registrar.

   7.7% of E-Commerce & Marketplaces peers do this.
