Shortwave — Design System
Shortwave automates email in round geometry: Poppins at 64px/400 white on deep space, 16-18px body, and flat text CTAs. AI-agent chat panels and inbox screenshots do the demonstrating while gradient auroras keep the dark canvas alive — the Google-alumni email client that pitches AI triage with a friendly, circular voice.
