- Don't clutter the layout with too many elements — screenshot shows generous whitespace and a clear focal point.
- Don't use sharp, square corners — screenshot shows consistent use of rounded corners and pill shapes.
- Don't use heavy, multi-layered shadows — screenshot shows subtle, soft elevation shadows.
- Don't use overly small touch targets — screenshot shows large, easily clickable buttons and navigation.

The design uses a clean white and slate palette (#FFFFFF, #F1F5F9, #0F172A) with a single vibrant purple accent (#5E51F8) for key calls-to-action. Typography relies on clean, modern humanist and grotesque sans-serif categories for high legibility.

The overall voice is professional and direct, emphasizing ease of use.
