Platform Design Languages

Defer to these canonical sources before applying the defaults in this file:

Apple: Human Interface Guidelines
Android: Material Design 3
Windows: Fluent 2 Design System
Web: WCAG 2.1 + platform-appropriate system

When the platform HIG prescribes a specific value (spacing, type size, target size), the platform value MUST be used. Use the defaults below to fill gaps or establish a cross-platform baseline.
