An unofficial Vercel-inspired system for precise developer platforms: adaptive neutral surfaces, compact operational UI, and production-ready elements across every Frontend Forever category.
Foundations
A public overview of the typography, palette, icon language, spacing, shape, and motion used throughout this AI Kit.
Style identity
Precision interface architecture built from monochrome planes, hairline grids, compact operational controls, and rare semantic color. The system moves between a bright marketing canvas and a dense dark product surface while preserving one typographic and spatial rhythm.

Guidelines
Imagery
Product-first compositions use real interface frames, terminal output, deployment graphs, and precise technical diagrams. Screenshots stay sharp, top-aligned, and contained by a quiet border; avoid lifestyle photography and decorative mockups that do not explain the product.
Layout
Center content in a 1200px rail with 24px desktop and 16px mobile gutters. Marketing sections use visible horizontal rules and occasional 48px grid lines. Split heroes collapse below 900px, dense grids step from four columns to two and one, and code surfaces scroll instead of compressing.
Concept
Use the file tree to move between the full reference preview, implementation guidance, portable tokens, and framework-ready styles. Each surface stays focused, so you can understand the system before copying code.
