App-based branding via Branding themes in Entra External ID
From Microsoft's description: “A new Live Preview feature also helps quickly visualize the changes before saving.”
In Entra External ID (EEID), customers can create a single, tenant-wide, customized branding experience that applies to all apps. We're introducing a concept of Branding "themes" to allow customers to create different branding experiences for specific applications. A new Live Preview feature also helps quickly visualize the changes before saving. For more information, see: Customize the sign‑in experience for your application with branding themes.
