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?

The issue discusses redesigning the map visualization to better communicate severances, crossings, and walking paths. Start by examining the current view component and styling in the codebase. Look for files handling map rendering, likely using a library like Mapbox or Leaflet within Svelte. The goal is to experiment with negative-space styling and line casing to indicate sidewalks, then later implement area permeability analysis. 'Done' means a new visual design that clearly shows walkability and crossings at various zoom levels.
