Thanks for the PR @edwardtay, great work overall!

A couple of suggestions to improve clarity and user experience:

Add a light mode version of the diagram

• Right now, the black diagram works well for dark mode, but it's not fitting for the light mode. Could you include a white/light version of the image and dynamically switch between them based on the user's theme?

Include an introductory paragraph before diving into component details
It would help to start the page with a short paragraph that provides a high-level explanation of the system; what it does, its core purpose, and how the components work together. That way, readers get context before jumping into the architecture diagram and component breakdown.

Will complete the fixes on my end.
