Sanity check on kerb and lit tags

Hello! I've just started using StreetComplete, and I want to make sure I understand the answers before I go through and make a bunch of garbage data.

In this picture, is the kerb a ramp, or flush?

The sidewalk deflects downwards, but it's not a ramp ramp like the example picture.

How about this one?

The kerb itself dips, but the sidewalk on this one looks more flat and does simply run into the road. And then it has the texture, obviously. Is this one different from the last one?

Also, just to check, I marked both of these sidewalks as "concrete". That's correct, right? I wondered about "concrete plate", because they're segmented, but the picture made concrete plate look much more substantial.

My other question was based on the "lit" tag for a bus stop. This bus stop has a street light near it, but there's no light on the bus stop itself. It sounds like that means it is lit? Would a non-lit stop just be one that is fully dark at night, then, with no kind of lighting anywhere near it at all?

This one is further from the street light, but still has line of sight. Lit?

Thanks very much for any help you have!
