Zarf Variables/Constants and imported components

[Riley-Brooksher]

Is there well defined behavior regarding variables and constants (defined at the package level) when components from that package are imported into a higher level package?

For reference, I am building my top-level zarf.yaml as a composition of many imported components from smaller packages broken up by functional area (storage, security, logging, etc). Widely applicable variables, like those defining storage endpoints, have use in components in multiple packages, and it doesn't feel very DRY to repeat those variable definitions everywhere they're needed.

Is there a recommended way of handling variables with component imports? Should I not be composing a top-level zarf.yaml with many imported components, and instead create a monolithic zarf.yaml manifest?

I appreciate any insight/assistance.
