C4 hierarchical path

Current layer: Component, explaining the key responsibility units within a Container.
Upper layer: Container, which defines the architectural boundaries to which these components belong.
Lower layer: Code View, only enter a small number of key code anchors when you need to trace the implementation entrance or change the impact surface.

Responsibility

Explain which key components within the apps/esp32_lvgl Container bear architectural responsibilities. The Component layer is not a comprehensive list of classes/functions, only objects that are helpful for understanding system boundaries, collaboration, or the impact of changes.

Boundaries

The boundary of Component View is limited to apps/esp32_lvgl Container; cross-container relationships should be explained back to the Container or Engineering Sequence perspective.

Relationship with business complexity

The component layer helps connect business stories to actual portal, orchestration, adaptation or infrastructure objects.
If a component directly hosts a Use Case, corresponding evidence should appear in the drill-down document of the organization/process model.

Correlation with technical complexity

Corresponds to Engineering Class / Structural Diagram: docs/engineering/class-structural-diagrams/apps-esp32_lvgl/class-structural-diagram.html.
Component-level reuse signs, external collaboration signs and complexity candidate points are still explained by the software structure model.
