Continue builds open-source AI coding in the IBM Plex family: Plex Sans at 36px/600, Plex Mono for 14px labels and body notes, engineering-white background, minimal chrome. The extension's config-file aesthetic extends to the site — a dev tool typeset like the editor pane it lives beside.

# Continue — Design System

> light, modern, medium, custom — deep decode (measured live)

Continue builds open-source AI coding in the IBM Plex family: Plex Sans at 36px/600, Plex Mono for 14px labels and body notes, engineering-white background, minimal chrome. The extension's config-file aesthetic extends to the site — a dev tool typeset like the editor pane it lives beside.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFF0F1` |
| border | `#D9D9DC` |
| text | `#020817` |
| text_muted | `#62656F` |
| primary | `#F9B4B4` |
| accent | `#020817` |
| link | `#020817` |
| secondary | `#FDECEC` |

**Using these colors**

- **Action color** `#020817` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#020817` — one role, not several (your action color).
- **accent** `#020817` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#F9B4B4` — a brand color — but the call-to-action uses #020817, not this.
- **secondary** `#FDECEC` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 75.1% · `#51537B` 7% · `#898AAA` 5.4% · `#A9ABBF` 4.4%

## Typography

- Heading: **IBM Plex Sans**
- Body: **IBM Plex Sans**
- Mono: **IBM Plex Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 36px / 600 · lh 40px · tracking -0.9px |
| body | 15px / 400 · lh 24px |
| small | 14px / 400 · lh 21px |
| eyebrow | 12px / 400 · tracking 2.4px |

- Weight ladder: 400 · 500 · 600 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 4px
- scale: 2px, 4px, 6px, 8px, 12px, 16px, 24px, 32px

## Radius
- base: 6px
- button: 6px
- card: 6px

## Primary button
- bg `None` · text `None` · radius None

## Motion
- durations: 150ms (dominant) · 200ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: color, background-color, border-color, text-decoration-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Layout (measured)
- nav: 21px

## Motion choreography (measured)
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0) · r 0px

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #171717 · underline

## Responsive (measured)
- breakpoints: 768px
- mobile (390px): hero 30px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
