An AI agent that resolves customer service conversations
The style
A bold editorial language with a warm, papery calm. Huge light-weight serif headlines are set extremely tight over pure black-on-white text, with oat and cream panels behind the product story. A single hot orange is saved for small highlights, and actions are plain black or white buttons with small, square-ish corners.

Layout
1576px container · 12 columns · 24px gutters
Patterns
- Wide single-column hero with generous vertical rhythm between sections.
- Twelve-column grid; content blocks usually span 4, 6 or 8 columns.
- Full-bleed bands for feature sections, inner content capped at the container.
- Reading text limited to roughly 65–72 characters per line.
Responsive principles
- Below md, grids collapse to a single column and side gutters drop to 16px.
- Type steps above h2 scale down one step on small screens.
- Navigation collapses to a disclosure menu below lg.
- Touch targets stay at least 44×44px on every breakpoint.
07
Motion
Durations and easing curves. Previews respect your reduced-motion setting.
- fast110ms
- base190ms
- slow310ms
ease-standard
ease-enter
ease-exit
Principles
- Motion is measured and calm, easing into place rather than snapping.
- Animate opacity and transform only; avoid animating layout.
- Respect prefers-reduced-motion by replacing movement with instant state changes or fades.
