Media and third-party tags on PDPs are the usual suspects.

FAQ
- PSI vs Lighthouse local?
- PSI when a key is configured; lab fallback otherwise. Methodology documents NA handling.
- Hydrogen / headless?
- If HTML is public we measure that URL. App shells can limit what PSI sees.
- Will you remove apps for me?
- No. The report tells you what is expensive; you decide in the admin.
