Summary of Changes

Hello @descorp, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the Architecture.md documentation by converting several key architectural diagrams from static images and ASCII art into interactive Mermaid diagrams. This change aims to improve the clarity, maintainability, and readability of the system's architectural overview, making it easier for developers to understand complex data flows and component relationships.

Highlights

• Documentation Enhancement: Replaced all static image and ASCII art diagrams within the Architecture.md file with dynamic and maintainable Mermaid diagrams.
• Improved Clarity: Introduced Mermaid flowcharts to visualize key architectural aspects, including data flow, module wrapper hierarchy, core interfaces, configuration hierarchy, event emission, payment component lifecycle, and error routing.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request is a great improvement, replacing ASCII art diagrams with much clearer and more maintainable Mermaid diagrams in the architecture documentation. The new diagrams accurately represent the system's data flow and component hierarchies. I've found one minor issue in one of the new diagrams that could affect its rendering, and I've left a suggestion to fix it. Overall, this is a valuable update to the documentation.

[gemini-code-assist]

The stroke property for the Checkout style has an invalid value. stroke:# will likely cause rendering issues with the Mermaid diagram. To fix this, you should provide a valid hex color code. Based on other diagrams in this file, stroke:#6c8ebf seems to be the intended color for this fill.
