Apple's Human Interface Guidelines (HIG) represent the gold standard for platform-native design. With its emphasis on clarity, deference, and depth, HIG provides a comprehensive framework for building beautiful, intuitive user interfaces.

Key Principles

The new system is built around three core principles that guide every design decision:

1. Clarity — Text is legible, icons are precise, and adornments are subtle
2. Deference — Fluid motion and crisp interfaces help people understand content
3. Depth — Visual layers and realistic motion convey hierarchy and facilitate understanding

Component Showcase

Here's a quick look at the updated component library:

<button class="px-5 py-2.5 bg-brand text-white
  rounded-lg text-sm font-medium">
  Filled Button
</button>

The rounded-lg class creates the distinctive rounded rectangle shape that defines HIG buttons, while the system color palette provides consistent, accessible color combinations across all Apple platforms.
