noice style LSP progress bar?

Hello, I was wondering if fidget could be customized to display an LSP progress bar like noice does. Some examples:

It looks like the bar serves as a background to the progress message. This seems like it would require highlighting different parts of the message separately. Is this currently possible in fidget?

The issue names no files, tests, or entry points; begin by finding fidget's progress rendering and customization APIs. Compare them with the noice examples and determine whether separate highlighting can support the requested background bar; record the supported configuration or the limitation.
