Performance, accessibility, best practices and SEO are what we aim at for every page, not a report to admire. How the checks run, which numbers we treat as real, and why an estimate never counts as a measurement.

A score of 95 is a list of things to fix. The landing pages are checked against the built output, not the dev server, with the desktop and mobile presets, and a change that drops a category needs a reason we would say out loud: a richer page can be worth a point, a careless one never is.

The other half of the rule is honesty about numbers. A size, a paint time or a score is quoted only when it was measured in a browser on the built files; anything else is labelled a hypothesis. It is slower to write things that way and much faster to trust them later.
