Detailed Description

Service Locator / Dependency Injection container

Manages service registration/discovery and provides typed access. Uses static allocation - no heap.

Two usage patterns:

1. Named services: registerService("display", &display) / get<IDisplay>("display")
2. Typed services: provide<IKeyboardProvider>(ServiceType::KEYBOARD, &kb) / request<IKeyboardProvider>(ServiceType::KEYBOARD)
