React UI Patterns

Core Principles

1. Never show stale UI - Loading spinners only when actually loading
2. Always surface errors - Users must know when something fails
3. Optimistic updates - Make the UI feel instant
4. Progressive disclosure - Show content as it becomes available
5. Graceful degradation - Partial data is better than no data
