    brandUrl: "https://www.xyz.com/",

I had this same problem, I have solved it by removing all theming from .storybook/manager.js and instead added it under light in .storybook/preview.js .

This is working but I now get a flash of Storybooks default theming before my custom theme loads 😦

// .storybook/preview.js

import { themes } from "@storybook/theming"
import storybookBrandImage from "./StorybookBrandImage.png"

export const parameters = {
    darkMode: {
        current: "light",
        light: {
            ...themes.normal,

            brandTitle: "yourTitle", 
            brandUrl: "yourURL",
            brandImage: storybookBrandImage, 

       }
       dark: {
            ...themes.dark,

       }
   }
}

If anyone knows a solution to the default theming flash before my custom theming loads, please let me know 🙏🏽

@nikkipantony Solution is great and the only thing I can add to improve this workaround is that you can keep yourTheme.js file, export it and spread it.

// yourTheme.js
export const brandTheme = {
  light: {
    base: "light",
    colorPrimary: "#222",
    colorSecondary: "#eed457",
    brandTitle: "JS",
    brandUrl: "https://en.wikipedia.org/wiki/JavaScript",
    brandImage:
      "https://upload.wikimedia.org/wikipedia/commons/thumb/6/6a/JavaScript-logo.png/600px-JavaScript-logo.png",
  },
};

// preview.js
import { themes } from "@storybook/theming";
import { brandTheme } from "./theme";

export const parameters = {
  darkMode: {
    current: "light",
    light: {
      ...themes.normal,
      ...brandTheme.light,
    },
    dark: {
      ...themes.dark,
    },
  },
};

Thanks Nikki!
