+- What was implemented: Delete project functionality with confirmation dialog and toast
+- Files changed:
+  - src/components/ProjectCard.tsx - new client component replacing Link, with delete button and confirmation dialog
+  - src/components/ProjectList.tsx - new wrapper component to manage project list state and toast notifications
+  - src/components/Toast.tsx - new reusable toast notification component
+  - src/app/dashboard/page.tsx - updated to use ProjectList instead of inline rendering
+- **Learnings for future iterations:**
+  - To enable client-side state updates (like removing items), extract list rendering from server components into client components
+  - ProjectList accepts initialProjects from server and manages state locally for immediate UI updates
+  - Use onDelete callback pattern to propagate deletion events from child (ProjectCard) to parent (ProjectList)
+  - Delete button uses e.stopPropagation() to prevent card click navigation when clicking delete
+  - Confirmation dialogs should disable close/cancel while action is in progress (isDeleting check)
+  - Toast component uses useCallback for handlers and auto-dismiss with setTimeout
+  - Toast animations can use TailwindCSS animate-in utilities (fade-in, slide-in-from-bottom-4)
+  - Delete icon appears on hover using group-hover:opacity-100 with parent group class
