Core Kotlin Multiplatform logger with zero third-party runtime dependencies. Two front-door APIs, Log for quick tag-based calls and Logger for structured logging, funnel through one pipeline so configuration applies uniformly. Ships on Android, iOS, macOS, JVM, JS (Node & Browser), Wasm/JS, Linux, and MinGW.

Optional coroutines support for KMP Logger: safe LogContext propagation across suspension points and thread hops. Depends on :logger via api, so consumers name its types transitively.
