keep-astro-frontmatter-clean

Summary

Keep the "Code Fence" (the area between ---) in .astro files focused on View Logic (fetching props, transforming data for display). Move complex business logic, data fetching wrappers, or heavy computations into separate .ts utility files.

Rationale

• Testability: Code inside .astro files is hard to unit test isolated from the markup. .ts files are easy to test.
• Readability: Huge frontmatter blocks hurt the scannability of the component structure.
• Reusability: Logic in .ts files can be shared across endpoints and components.

Guidance

1. Extract: If the frontmatter exceeds 20-30 lines, consider extracting classes or functions.
2. Imports: Import the logic and call it.
