What is the current behavior?

The project is currently using Next.js v15.5.11 with Node.js >=18.18. The build process uses explicit --turbo flag which is no longer needed in Next.js 16 as Turbopack is now the default bundler.

Issue Number: N/A

Current stack:

• Next.js: ^15.5.11
• Node.js: >=18.18
