Subsystems are self-contained OS components under subsys/, each with its
public API in include/pbl/<name>/. Most follow the same pattern: users
declare what they need next to their own code, the subsystem collects
it at link time, and a Kconfig option selects the backend.
The API reference documents every subsystem’s interface.
