## Context

The USD Layer Manager application uses ImGui for its user interface. Currently, ImGui uses its default font, which is functional but not optimized for modern UI aesthetics. The proposal outlines changing to the Inter font to improve readability and visual appeal.

## Goals / Non-Goals

**Goals:**
- Load and apply the Inter font in ImGui initialization
- Ensure consistent font usage across the application UI
- Minimal performance impact on startup

**Non-Goals:**
- Implement font selection options for users
- Support multiple font weights or styles beyond regular
- Modify font rendering beyond basic loading

## Decisions

- **Font Choice**: Use Inter Regular (Inter-Regular.ttf) as it provides excellent readability for UI text. Considered alternatives like Roboto, but Inter is specifically designed for interfaces and is more modern.
- **Loading Location**: Load the font in the main application initialization, likely in src/main.cpp where ImGui context is set up, to ensure it's available before any UI rendering.
- **Font Size**: Maintain default ImGui font size (13pt) to avoid layout changes.
- **Fallback**: If Inter font fails to load, fall back to default font to prevent application failure.

## Risks / Trade-offs

- **Font File Dependency**: Requires Inter-Regular.ttf to be included in project assets. Risk of missing file → Mitigation: Add to version control and build process checks.
- **Startup Performance**: Loading a custom font may add slight delay to initialization. Risk: Negligible impact expected, as font loading is typically fast.
- **Cross-Platform Compatibility**: Font rendering may vary slightly on different platforms. Risk: Test on target platforms (Windows primarily).
