Turborepo — decoded design system

Decoded design system

Turborepo's decoded design system: background #FFFFFF, text #0A0A0A, accent #006BFF, link #006BFF, primary #006BFF; type scale h1 72px / h2 40px / body 16px; 8px spacing base; 0px base radius. The single interactive/action color is #006BFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #006BFF — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link are all #006BFF — one role, not several (the action color).
• accent #006BFF — 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.

# Turborepo — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0A0A0A` |
| text_muted | `#676767` |
| primary | `#006BFF` |
| accent | `#006BFF` |
| link | `#006BFF` |
| button_bg | `lab(2.75381 0 0)` |
| button_text | `lab(100 0 0)` |

**Using these colors**

- **Action color** `#006BFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link` are all `#006BFF` — one role, not several (your action color).
- **accent** `#006BFF` — 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.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 93.8% · `#EFEFF1` 3.7% · `#938F92` 2.6%

## Typography

- Heading: **SFMono-Regular** _(free fallback: JetBrains Mono)_
- Body: **SFMono-Regular** _(free fallback: JetBrains Mono)_
- Mono: **SFMono-Regular**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 72px / 600 · lh 72px · tracking -3.6px |
| h2 | 40px / 600 · lh 60px · tracking -2px |
| h3 | 32px / 600 · lh 48px · tracking -1.6px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 20px |

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

> **Fonts —** SFMono-Regular may be proprietary — safe free fallback: JetBrains Mono (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 14px, 16px, 20px, 24px, 32px — snap all gaps/padding to these

## Radius
- base: 0px
- button: 8px
- card: 8px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `lab(2.75381 0 0)` / `lab(100 0 0)` | none | 8px | 8px 16px 8px 16px | 500 16px | none |
| secondary | `lab(100 0 0)` / `lab(48.496 0 0)` | 1px solid lab(90.952 0 -0.0000119209) | 8px | 0px 6px 0px 12px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: background `oklab(0.145 -0.00000143796 0.00000340492 / 0.9)`
- secondary hover: background `lab(96.52 -0.0000298023 0.0000119209)` · color `lab(7.78201 -0.0000149012 0)`
- transition: `all 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 100ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: color, background-color, border-color, outline-color

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

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- nav: 65px sticky · border-bottom 1px solid lab(90.952 0 -0.0000119209) · bg lab(98.26 0 0)

## Motion choreography (measured)
Load order: `svg.lucide` @0ms
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0.2) · r 0px
  - enter: opacity from 0 · 300ms linear

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

## Components (measured)
- input: h 64px · r 0px · bg rgba(0, 0, 0, 0) · placeholder lab(48.496 0 0)
  - focus ring: `` — this exact construction, don't invent your own
- disabled: bg rgba(0, 0, 0, 0) · text lab(2.75381 0 0)

## Responsive (measured)
- breakpoints: 360px · 400px · 448px · 481px · 640px · 768px
- mobile (390px): hero 60px · body 16px · nav: hamburger

## 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.
