NamespaceSummary (test-first) renders the substrate ns line from live cluster namespaces (system-filtered, sorted, capped). Handler now overlays both node specs and the ns line via a single cached liveOverlay(). Removed the inline SUBSTRATE/STAGES/NS data — /api/atlas.json is the single source; the page shows an error banner on fetch failure instead of stale data. GPU model naming intentionally NOT done: koala's node has no GPU product label (only nvidia.com/gpu count), so "1× GPU" is the API's truth — naming the RTX 5070 would need GPU-feature-discovery, out of scope. Verified: build/vet/lint(0)/test green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
