Static small fixture

This fixture represents the simplest possible workload: one kilobyte of static HTML with no scripts and no external resources. It measures the fixed per-fetch overhead of each tool (process launch, engine initialization, HTTP request, parse, extract) with no rendering work to amortize that cost against.

Under this workload, a heavyweight engine like Chromium cannot amortize its startup cost and will look disproportionately expensive compared to servo-fetch. The spa-heavy fixture tests the opposite extreme.
