Note: Units are explicitly milliseconds (ms) and microseconds (us).

This header exposes minimal timing helpers used throughout the application code for short, platform-dependent delays. The concrete behavior (blocking, sleep, busy-wait, tick resolution) depends on the platform-specific implementation behind these APIs.

Implementations should document any real-time or concurrency restrictions (for example, whether the functions may be called from interrupt context). Consumers of these APIs should avoid long blocking delays in time-critical or interrupt contexts.
