Decide AI. Mint signal.

Decide AI operates as a midnight intelligence command center — a near-black canvas (Deep Obsidian) where massive display type dominates and a single mint-green accent (#73ffb9) punctuates the silence. The system speaks in two voices: whisper-quiet product cards on a dark surface, and oversized editorial headlines at 110–220px that fill the viewport like a magazine spread. Typography is the entire personality: PP Neue Montreal at display weights with aggressive negative tracking collapses the visual gap between letters, creating geometric solidity at extreme sizes. Components are minimal — pill-radius buttons, thin hairline borders in #e5e7eb, and almost no decoration. Color is rationed: a 2% colorfulness budget means the green accent appears as bars, icons, and rare punctuation rather than full surfaces. Density is comfortable and spacious, with generous vertical gaps and content centered in wide container widths.
