getirfinans design key principles are:

1. Minimal color. Near-black and white dominate. Green only for success.
2. Generous whitespace. Let content breathe. Don't crowd the interface.
3. Clear hierarchy. Size and weight create focus, not color.
4. Sentence case. Buttons and headings use sentence case, not Title Case.
5. Subtle interactions. Hover states are gentle, not flashy.

The palette is intentionally limited. This creates visual consistency and ensures green stands out for success states.
