xAI runs a restrained near-monochrome editorial system on a warm-white canvas. Type leads the visual hierarchy: oversized display headlines at near-100% line-height with tight negative tracking sit above generous breathing room, while GeistMono punctuates the interface with terminal/code fragments. The single defining interaction is a pill-shaped, pure-black filled button — everything else is ghost, outlined, or surface-toned. Cards are flat, borderless, and warm-cream (#f9f8f6); depth comes from a single hairline ring rather than shadow stacks. Color is rationed: a warm off-white page, cream cards, near-black ink, and the occasional vivid accent (Beta pill, traffic-light terminal dots, gradient orbs) that earns attention precisely because the rest of the page refuses it.
