Render-blocking
A render-blocking resource is one the browser must fetch and process before it can paint anything.
Why it matters
An external stylesheet is a full round trip before the first character appears, which inlining removes entirely.
How it is measured
Count stylesheet link elements in the document head. Zero is the target on a static-first site.
