Title: Implement Country Themes

Domain: Design (UI)

Difficulty: Intermediate

Steps:

Add theme-switching logic.
Apply colors based on the country.
Expected outcome: UI theme changes based on country.

This task proposes implementing a Multi-Country Themes UI to allow the
application interface to adapt visually based on selected countries or regions.

The feature should:

• Support country-specific themes (colors, imagery, or branding)
• Allow easy switching between country themes
• Ensure visual consistency and accessibility across all themes
• Be scalable to support additional countries in the future
• Avoid performance degradation when loading or switching themes

Applying multi-country UI themes will improve localization, user engagement,
and regional relevance while maintaining a consistent core experience.
