Prism UI Kit

A neo-brutalist design system for Flutter. 20+ components built with structural honesty — no shadows, no blur, no Material, no Cupertino. Just raw, intentional form.

Philosophy

Prism rejects decorative UI. Every component exposes its grid anatomy:

• No shadows — depth comes from borders and color contrast
• No blurs — transparency is binary, not filtered
• No Material/Cupertino — platform-agnostic editorial aesthetic
• Bold accents — amber, lime, coral, sky on dark ink canvas
• Structural borders — every component shows its edges
