Hey there - I've reviewed your changes - here's some feedback:

• The workflow only runs on the “master” branch, but many projects now use “main” by default—consider updating the branch filter or making it configurable.
• You’re uploading ./out but never run next export after next build, so the static files won’t actually be generated—add an export step to populate the out folder.
• You cache only .next/cache, but adding a cache for node_modules (or your package manager’s install directory) can further speed up CI runs.
