Guidance on writing new components that integrate with the Fluent Frame design system?

[logan2z]

I'm planning on writing a component library that uses the FAST web components as a base but I will need to add additional custom components to my library and want my own components to react to Design System configuration changes like the base FAST components.

Is there a document/tutorial somewhere that discusses what a component author needs to do to enable their new component to play well with the Fast Frame design system? For example, how to implement the component so that it reacts appropriately to changes in the baseLayerLuminance (light/dark mode), cornerRadius etc. so the behavior is consistent with that of the FAST components?
