The global shell eagerly imported the login dialog and libraries overlay even when visitors never opened them. Load each through React.lazy on its first explicit open, with a local Suspense boundary. Keep it mounted after that first open so Radix can handle closing animations and subsequent opens.

Production build comparison using the same installed dependencies:

Client entry and static JS imports	Before	After
Raw bytes	1,305,258	1,278,499
Gzip bytes	397,499	389,414
Brotli bytes	326,403	319,692

This moves 8,085 gzip bytes out of the entry's static import graph. Both overlays emit separate async chunks. These figures exclude route chunks and are not a whole-page transfer measurement; the first opening now waits for its async chunk.

Summary by CodeRabbit

• Performance
  • Libraries and login interfaces now load only when opened, helping improve initial application loading performance.
  • Unused overlays and modals no longer load until they are requested.

📝 Walkthrough

Walkthrough

Changes

The contexts now lazy-load the libraries overlay and login modal. Each component loads when its open function is called and renders through React.Suspense.

Lazy UI component loading

Layer / File(s)	Summary
Lazy libraries overlay loading src/contexts/LibrariesOverlayContext.tsx	The provider dynamically imports LibrariesOverlay, tracks the first open request, and renders the overlay conditionally inside React.Suspense.
Lazy login modal loading src/contexts/LoginModalContext.tsx	The provider dynamically imports LoginModal, tracks the first open request, and renders the modal conditionally inside React.Suspense.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e77cc

The login modal and libraries overlay now load on first use, reducing initial client bundle size while preserving their open, close, and subsequent-open behavior. No merge-blocking risk remains.
