Description

When a font fails to load, the error message is not user-friendly. Need graceful fallback with clear warnings.

Current Behavior

• Silent fallback when font not found
• No warning to user about which font is being used
• Error messages are technical

Desired Behavior

1. Validate font exists at startup
2. Show clear warning: "Font 'JetBrains Mono' not found, using 'Menlo'"
3. Suggest installation command for missing fonts
4. Log which font is actually being used
