Use Shadcn UI or Shared Components Only

When adding new UI elements, components, or making UI/content modifications:

• ALWAYS check if a matching component exists under src/components/ui/ or src/components/shared/.
• Prefer existing Shadcn UI primitives (e.g., toast, button, card, etc.) to keep the codebase consistent.
• Do not introduce non-standard styling libraries or custom UI utilities unless absolutely necessary.
• Ensure styling and layouts remain consistent with the existing application design system.
