Statsig measures in Geist: 65px/500 'Measure what ships. Ship what matters.' in gunmetal #1F2328, 16px body, and ink-dark 30px-radius pill CTAs. Experiment dashboards and metric deltas fill the panels — an A/B testing platform whose own page reads like a clean experiment readout, hypothesis in the headline.

# Statsig — Design System

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

Statsig measures in Geist: 65px/500 'Measure what ships. Ship what matters.' in gunmetal #1F2328, 16px body, and ink-dark 30px-radius pill CTAs. Experiment dashboards and metric deltas fill the panels — an A/B testing platform whose own page reads like a clean experiment readout, hypothesis in the headline.

## Colors

| Role | Value |
|------|-------|
| bg | `#F6F6F6` |
| surface | `#E9E9E9` |
| border | `#D5D6D7` |
| text | `#1F2328` |
| text_muted | `#707376` |
| primary | `#000000` |
| accent | `#1F2328` |
| link | `#000000` |
| button_bg | `#1F2328` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#1F2328` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `link` are all `#000000` — one role, not several.
- `accent`, `button_bg` are all `#1F2328` — one role, not several (your action color).
- **accent** `#1F2328` — 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): `#F6F6F6` 87.4% · `#4F73AC` 7.8% · `#E3E8EC` 4.8%

## Typography

- Heading: **Geist**
- Body: **Geist**
- Mono: **Geist Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 65px / 500 · lh 72px · tracking -2px |
| h2 | 40px / 600 · lh 50px |
| h3 | 32px / 600 · lh 40px |
| body | 14px / 400 · lh 24px |

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

> **Fonts —** Geist — free, on Google.

## Spacing
- base unit: 10px (inferred from the measured scale)
- measured scale: 3px, 5px, 6px, 8px, 10px, 12px, 16px, 20px, 30px, 40px — snap all gaps/padding to these
- section rhythm: 100px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 30px
- card: 10px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#1F2328` | none | 30px | 10px 20px 10px 20px | 600 16px | rgb(212, 215, 220) 0px 0px 0px 1px inset |
| secondary | `#1F2328` / `#FFFFFF` | none | 30px | 6px 20px 6px 20px | 600 14px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`

## Shadows (elevation)
- card: `rgba(27, 37, 40, 0.05) 0px 0px 20px 0px`

## Motion
- durations: 400ms (dominant) · 200ms
- easings: `ease-in-out` (dominant) · `ease`
- animated properties: opacity, box-shadow, border-bottom

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)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 100 | 858 | — | — | 100/0 | — |

## Motion choreography (measured)
Load order: `div.vocColumnScroller`×2 @0ms → `div.vocColumnScroller` @0ms
- scroll reveal: 3 elements rest at a pre-reveal state (3 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 840px
- mobile (390px): hero 40px · body 14px · 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.
