Rethink styling

The current view is quite messy.

Backing up, what're the important elements to communicate?

- Severances
- It should be clear if walking on one/both sides of one is possible (has a sidewalk or not)
- The (often few) crossings over them
- The usable walking paths of all sorts (dedicated sidewalks, small residential streets where there might not be any, but it's generally low-stress to walk and cross anywhere)

Here's a negative-space attempt, starting from blank.


At very low zoom, this has some problems. The crossings get squished; in some places it looks like there's a crossing over a severance, but it's actually parallel to it.

And it's also impossible to see sidewalks along a severance or not. For the second problem, maybe it's possible to play with the line casing for that.

Once this base idea is working, I want to go further and basically do an area permeability analysis. Within each zone surrounded by severances, how easy is it for people to walk through?
