incorrect icon: pencil

### Describe the Issue

The pencil outline icon isn't actually an outline, it looks filled. Also if this icon is small it just looks like a diagonal line.

### Expected Behavior

Can you make it more like a chunky pencil? Then you might be able to get a proper outlined version and more visible as a pencil as a small icon then a diagonal line.

Same goes for the company logos, these doesn't appear to have an outlined version

Start by locating the pencil outline icon and the company logo assets referenced in the issue. Compare their appearance at small sizes and determine whether the requested chunky, outlined treatment applies to both. Done means the pencil reads clearly as an outlined pencil at small sizes and the relevant logos have an outlined version, but the issue does not name files or tests.
