The dashboard shell is live, but the map and panel bundles are still loading into the browser. On a fresh pnpm dev boot, Next.js may spend a moment compiling these client chunks before the live atlas appears.

Normal On Dev
First-load chunk compilation is slower than warm reloads.
Next Step
If this persists after a refresh, it’s a real runtime problem rather than compile lag.
