feat: show navbar immediately while metadata.json loads#196
Merged
Conversation
- Add animated skeleton placeholder in the Navbar dropdown slot while useTestMetadata() is fetching, so layout doesn't shift on load - RunIndex: render Navbar + content skeleton during isLoadingBenchmarkRuns instead of a bare <div>Loading...</div> that hid the navbar entirely - RunComparison: same fix

Summary
metadata.jsoncan be slow to load. Previously the entire page render (including the navbar) was blocked behind the metadata fetch, showing just a bareLoading...div.Changes
Navbar.tsx: WhileuseTestMetadata()is in-flight on benchmark routes, render an animated skeleton placeholder in the dropdown slot so the navbar is immediately visible and the layout doesn't shift when the select appears.RunIndex.tsx/RunComparison.tsx: Replace the early-return<div>Loading...</div>with a full layout that renders<Navbar />plus skeleton content placeholders. The navbar now shows instantly while metadata loads.
