Brainfish
A neo-brutalist B2B-AI support interface built on a white canvas with a single high-voltage lime accent (#a3e635), hard 2px offset drop-shadows, square-to-slightly-rounded edges, and the Geist sans typeface. The system reads as confident and technical — large 56px display headlines with tight negative tracking and italic serif emphasis words, hairline-bordered metric cards, a deep charcoal "enterprise-ready" band, and lime CTA buttons that sit on black borders with hard shadows rather than soft elevation.
