+//! # Core Module — Manager and Executor Layers
+//!
+//! Defines the two architectural layers that drive rendering: **Context** (Manager) owns GPU hardware
+//! resource lifecycle (Device, Queue, Surface), and **Renderer** (Executor) orchestrates draw calls by binding
+//! Material pipelines and Mesh vertex data into a RenderPass.
+//!
+//! ## Interaction with Other Modules
+//! - `context` consumes errors from `utils`, holds Frame references during frame loops.
+//! - `renderer` receives Device/Queue references from Context, uses Materials from `resources`.
+//! - `frame` is consumed by both Context (begin_frame → end_frame) and Renderer (render → present).
