> Electric blue ripple on white paper. A clean editorial canvas where a single vivid blue flows like liquid from corner to corner, making every interactive element feel switched on.

Arcade's visual system is a white-canvas product surface accented by one saturated electric-blue (#2142e7) and a signature flowing blue gradient that anchors the hero. Typography is Inter across all sizes, with weight concentrated in the 400–700 band and tight negative tracking on display sizes that tightens the type optically as it scales. The interface reads as functional and quiet: gray-on-white content blocks, thin borders, compact 12–16px radii, and cool-tinted shadows built on rgba(17,24,39,...) that keep every elevated surface feeling on-brand. Color is rationed — one blue does the work of accent, CTA, and focus — while everything else is a neutral ramp. Density is comfortable but not airy: 8px and 12px gaps dominate micro-spacing, 32–48px separates sections.
