Priority fixes for totalenergies.fr

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

1. Priority 1 · Harden

   Content Security Policy present

   Observed: The homepage response did not include a Content-Security-Policy header.

   Why it matters: A CSP limits where scripts, styles and frames can load from, which reduces the impact of injected or compromised third-party code.

   What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

   50% of Energy, Electricity & Gas peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 3 external scripts without async or defer.

   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.

4. Priority 4 · Accelerate

   HTTP/3 advertised

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

   20% of Energy, Electricity & Gas peers do this.
