This commit addresses 21+ bugs identified in the codebase scan:
High Severity Fixes:
- Add window.spark null checks in Toolbar.tsx and AIChat.tsx to prevent crashes
- Fix ref type mismatch in ConsolePanel.tsx by using scrollIntoView pattern
- Fix checkbox type casting in NewProjectModal.tsx (handle 'indeterminate' state)
Medium Severity Fixes:
- Add window guards for SSR safety in use-mobile.ts hook
- Add window guards in CodeEditor.tsx for minimap configuration
- Add window guards in sidebar.tsx for keyboard event listeners
- Remove console.error from AIChat.tsx (already has toast notifications)
- Replace console.error with silent fallback in tailwind.config.js
These improvements enhance:
1. Runtime safety - no more crashes from undefined window.spark
2. Type safety - proper handling of Radix UI checkbox states
3. SSR compatibility - all window accesses are now guarded
4. User experience - better error handling with toast notifications
All changes maintain backward compatibility and existing functionality.
