Hi @Aamod007 sir,

The new CustomizeCTA.timezone-boundaries.test.tsx test suite passes locally (5/5 tests), and the component-specific tests run successfully.

The current CI failure appears to come from existing repository-wide TypeScript issues in:

app/generator/components/EditorPanel.type-compiler.test.tsx
app/generator/components/PreviewPanel.type-compiler.test.tsx

These files are outside the scope of this PR, which only adds timezone boundary test coverage for CustomizeCTA.

Please let me know if any changes are needed from my side. Thank you!
