Platform Design Languages
When writing UI ingredients or recipes, refer to these canonical platform design sources. Cookbook artifacts MUST NOT specify values that contradict the platform HIG.
Canonical sources
- Apple: Human Interface Guidelines
- Android: Material Design 3
- Windows: Fluent 2 Design System
- Web: WCAG 2.1 + platform-appropriate system
How this applies to cookbook authoring
- When specifying spacing, type sizes, or target sizes in an ingredient's Appearance section, defer to the platform HIG. If the platform prescribes a value, use it.
- When the HIG has no opinion, specify a cross-platform default and note it as such.
- In the Platform Notes section of an ingredient, list any platform-specific overrides with links to the relevant HIG section.
