Scenario-based tutorials and reference architectures

What content needs to be created or modified?

Add scenario-based tutorials and/or reference architectures, ideally tailored to industries or common real-world scenarios, to showcase common architecture patterns using Radius.

Describe the solution you'd like

Create a set of guided tutorials/blueprints that walk users through end-to-end solutions (and the architecture behind them), such as "retail/e-commerce", "SaaS multi-tenant", "data processing pipeline", etc., focusing on commonly used patterns and how to implement them with Radius.

Where should the new material be placed?

Please suggest a location in the docs structure where this content should reside, or a URL path if known.

AB#18062

Start by reviewing the Radius documentation structure and existing tutorials and samples to identify where scenario-based content belongs. Define the scope and architecture patterns for the proposed real-world scenarios, then document end-to-end guided solutions and confirm that the tutorials clearly explain how to implement them with Radius.
