  - Implemented minimal visual ARCH logo indicator for AUR packages.
  - Standardized all AUR-related UI elements (checkboxes, badges) to official Arch Blue (#1793d1).
- Theme System: Refactored useTheme hook to a global Context Provider for perfect animation sync.
- Animations & UI: Enhanced drawer animations (slide-up/down), tooltips, and hover states using GSAP.
- Performance: Optimized app filtering with useMemo to prevent re-renders; fixed reconciliation issues.
- Fixes: Resolved hydration mismatches and malformed HTML tags.
- Docs: Updated README and CONTRIBUTING guidelines.
