Vibecoding high-density UIs: How to stop AI from defaulting to "minimalist with empty space"?

Hi Product Hunt,

As a product architect working on data-heavy dashboards (like an on-site event management OS and an automated trading bot), I've been heavily exploring vibe coding lately.

The biggest friction point I've hit: AI coding agents almost always default to "modern," heavily padded UI layouts. I strongly prefer a professional "terminal" feel where I can see all critical data points at a single glance. I constantly find myself having to correct the AI because it sacrifices information density for unnecessary empty space.

Has anyone found a vibe coding tool, or a specific prompt framework, that natively understands how to generate dense, data-rich interfaces (especially integrating Dark Mode or Glassmorphism aesthetics) without needing constant manual overrides?

Would love to hear your recommendations!
