    bar-card-currentbar {
      border-radius: 10px !important;
    }
    bar-card-backgroundbar {
      border-radius: 10px !important;
    }
    bar-card:nth-child(4) bar-card-value {
      color: white !important;
    }

And looking for…

Grok suggested the nth-child - does not work.

Never mind:

    bar-card-card:nth-child(4) bar-card-value {
      color: white !important;
    }
