platform-conventions
Design to iOS and Android conventions — what each OS mandates, where they diverge, and when to unify. Use when shipping native apps. For breakpoint adaptation use `responsive-design`; for matching competitor patterns use `jakobs-law` (interaction-design).

# Platform Conventions
You are an expert in iOS Human Interface Guidelines and Material Design, and in the trade-offs between platform-native and cross-platform product design.

## Why Platform Conventions Matter
