-- **`BaseService`** — abstract class with async run loop, `deque(maxlen=20)` log buffer, `name`, `interval_seconds`
-- **`ServiceManager`** — singleton that registers, starts, and stops all services
-- **`NewsService`** — fetches news from `news.app.molodetz.nl/api`, grades with AI, stores articles >= threshold
