- **Primary text (`#000000`)** — uses `ink` token
- **Secondary text (`#333333`)** — uses `ink-soft` token
- **Accent (`#6933FF`)** — uses `accent` token
- **Muted (`#6933FF`)** — uses `muted` token
- **Borders (`rgba(234, 236, 240, 1)`)** — uses `line` token

## Typography

- **Display:** humanist-sans
- **Body:** humanist-sans

- Use humanist sans-serif (Poppins/Open Sans) for a friendly yet professional technical feel.
- Maintain tight negative letter-spacing for large display type to create a cohesive visual block.
- Ensure body text has ample line-height (1.5-1.7) for technical readability.

## Layout

Full-width hero sections alternating with centered content containers.

*Rhythm:* Standard 4px grid based spacing with consistent 24px gutters for layout alignment.

## Elevation & Depth

- 0px 2px 4px 0px rgba(0, 0, 0, 0.075)
- 0px 0px 5px 0px rgb(128, 128, 128)
- Borders: 1px solid #EAECF0

## Shapes

- `sm`: 4px
- `md`: 8px
- `lg`: 12px
- `pill`: 9999px

## Components

- **button:** High-contrast solid purple (#6933FF) for primary actions, pill-shaped with white text. Secondary buttons are outlined with purple borders and dark text.
- **card:** Clean, minimal cards with subtle borders and slight shadows for elevation.
- **input:** Standard form inputs with light grey borders and 8px border-radius.
- **hero:** Large, left-aligned text over a geometric, light blue/cyan gradient background.

## Do's and Don'ts

**Don't:**
- Don't use a wide, decorative serif font — the screenshot shows a clean, modern humanist sans-serif approach.
- Don't use a muted, desaturated color palette — the screenshot features a vibrant, high-chroma purple accent.
- Don't use complex, heavy drop shadows — the screenshot uses very subtle, soft elevation for depth.
- Don't center-align all hero text — the screenshot shows the main headline and supporting copy aligned to the left.
- Don't use decorative or handwritten font styles — the screenshot maintains a strictly professional, clean aesthetic.
- Don't use dark backgrounds for primary CTAs — the screenshot uses a bright purple solid fill for the 'Start free' button.
