Add a benchmarks/ workspace package with a reproducible performance harness measuring four dimensions of TypeStyles performance against a 50-component reference design system: CSS generation time, extracted CSS file size across all naming modes, runtime injection latency, and SSR collection overhead. Includes a Vanilla Extract comparison using the same 50-component design system ported to recipe()/style()/createThemeContract() APIs. Key results (Apple Silicon): - Style registration: ~1.0ms (50 components + 8 token namespaces + 3 themes) - Selector calls: ~0.10ms for ~90 invocations - Extracted CSS: 19.0–31.4 KB raw (4.7 KB gzip) across naming modes - SSR collection: ~1.1ms per request - vs Vanilla Extract: comparable file sizes, both sub-2ms registration Also: - CI benchmark job with regression detection (20% timing / 5% size thresholds) - Docs benchmarks page with methodology and honest caveats - Fix: reset() now clears registeredNamespaces (was a gap in test cleanup) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Timing varies ~3x between Apple Silicon and CI VMs — a checked-in baseline from one platform can't reliably gate the other. File sizes are deterministic and platform-independent, so they're the only regression signal in CI. Timing results are still printed for visibility.
