Map visualizations do not apply theme colors when using Embedded Analytics JS or the React SDK

Describe the bug

When using themes in Embedded Analytics (both React SDK and Embedded Analytics JS), map visualizations do not respect the applied theme colors. Other visualization types (bar, line, row charts, etc.) correctly apply the theme, but maps continue using default colors even when no custom colors are set.

This happens both in my embedded environment and on the public Metabase Embedded Analytics SDK demo site.

To Reproduce

Go to: https://embedded-analytics-sdk-demo.metabase.com/

1. Click New Custom Exploration.
2. Choose From Scratch → Select Customers.
3. Under Summarize, select Count.
4. Under Group by, select State.
5. Click Visualize and switch to a Map visualization.

Notice that the map colors do not change, while other visualization types do.

Expected behavior

Map visualizations should apply the active theme’s color palette in the same way other visuals do.

Additional context

No response

Reproduce the issue on the Embedded Analytics SDK demo using the stated Customers, State, Count, and Map steps, then compare the map with bar or line visualizations under the same theme. Trace the React SDK and Embedded Analytics JS theme handling for map colors. Done means map visualizations use the active theme palette when no custom colors are set.
