Nextjs Shadcn

It enforces client boundary hygiene, proper server action usage (mutations only, not data fetching), and the new async params API. The opinionated file organization puts route-specific code in route groups and global utilities at the root. Notably pushes back against generic AI aesthetics with rules like "no purple gradients" and icon-first UI. Includes integration with next-devtools-mcp for live error inspection instead of copy-pasting stack traces. Uses bun exclusively and always imports with @ aliases. Best for greenfield Next.js projects where you want disciplined architecture from the start.
