What Apple publishes at depth

• Components and technologies (Siri, widgets, etc.)
• Continuous what's new channel

Transferable principles for AwesomeDS

1. Platform literacy first — respect system conventions before brand divergence.
2. Materials & depth are semantic (hierarchy), not pure decoration.
3. Typography hierarchy is a first-class foundation equal to color.
4. Accessibility is foundational, not a bolt-on chapter.
5. Icons have strict production systems (grid, weight, perspective).
6. Spatial / multi-platform thinking (safe areas, focus, input modality).

Anti-imitation

• Do not copy SF Symbols, San Francisco, or Apple product chrome.
• Transfer systems thinking and foundation taxonomy.
