Walkthrough

The updates modify the favicon configuration in the layout metadata for the Snow Leopard app and refactor the UI for the "Document Not Found" prompt in the always-visible-artifact component. The favicon declarations are centralized in metadata, and the document creation prompt receives a new structure and styling, with no changes to its logic.

Changes

File(s)	Change Summary
apps/snow-leopard/app/layout.tsx	Centralized favicon declarations in the metadata object and removed the manual favicon link tag.
apps/snow-leopard/components/always-visible-artifact.tsx	Refactored the "Document Not Found" UI: new card-based layout, improved button styling, and simplified header; no logic changes.

Poem

In the land of Snow Leopard, changes abound,
Favicons now in metadata are found.
The document prompt wears a brand new face,
With cards and buttons neatly in place.
A rabbit hops by, giving a cheer—
“Your UI is clearer, your icons sincere!”
🐇✨

apps/snow-leopard/app/layout.tsx (1)

40-44: LGTM! Proper favicon configuration centralization.

The favicon declarations have been correctly moved to the metadata configuration, which is the recommended approach in Next.js 13+ app directory. Using the same /favicon.ico file for all icon types (icon, shortcut, apple) is a common and valid practice for basic favicon setups.

apps/snow-leopard/components/always-visible-artifact.tsx (5)

24-25: Good addition of UI components for the refactored design.

The new imports for Card, CardContent, and Skeleton components support the enhanced UI structure for the document not found screen.

---

316-318: Clean header simplification.

Removing the "Document Not Found" text from the header and keeping only the SidebarTrigger creates a cleaner, less cluttered interface. The document not found message is now better positioned in the main content area.

---

322-331: Excellent preview card implementation.

The mini preview card with skeleton loaders provides a nice visual representation of what a document would look like. The responsive sizing (w-44 h-32 sm:w-52 sm:h-36 md:w-56 md:h-40) ensures good display across different screen sizes, and the skeleton placeholders give users a clear visual cue about the document structure.

---

334-337: Improved content hierarchy and readability.

The centered heading and description provide better visual hierarchy and are more user-friendly than the previous implementation. The text structure is clear and accessible.

---

340-358: Better button layout and accessibility.

The vertical stacking of full-width buttons with consistent sizing (size="sm", w-full) provides better touch targets on mobile devices and improved visual consistency. The loading state handling with centered spinner and proper disabled states maintains good UX during document creation.
