- Deleted the .env and src/env.d.ts files as they are no longer needed.
- Updated BaseLayout to require title and description props directly, ensuring better clarity in component usage.
- Adjusted various pages to pass explicit title and description values, enhancing SEO and user experience.
- Increased print width in .prettierrc.mjs for improved code formatting.
