These conditions are probably not hugely useful for most card users, but
allows the inbuilt automation systems to be used for card internal

- Much improved API cleanliness and testability to allow further
extensibility in future
- Simplified code in `live` view
This technically contains a small change in how overrides work in the
`live` view. Since that change is _closer_ to the documentation, and
since this is likely to be rarely used, this is not considered a
breaking change. Previously, overrides for a given live camera would
always render _as if_ that camera was selected, vs was actually
selected. Now, overrides will only apply in the live view when the
camera is _actually_ selected. If this is an issue for you in practice,
lets discuss.
