Technical Introduction
This entry explains architecture, boundaries, and working logic of the shop system.
What this system is
The shop is a modular PHP system with clear responsibilities for routing, session, security, data access, and rendering.
Technical guardrails
- Routing centrally decides which page is active.
- Session carries stable runtime context for language, page, and navigation.
- Model functions provide data, views render, services coordinate.
- Docweb documents decisions close to the real code flow.
System layers
The request flows through entry, core, business logic, and rendering in clear layers.
