Stytch — Design System

light · modern · medium · custom · confidence 92% · deep decode

Stytch keeps auth friendly: Booton at a compact 40px/700 in warm ink #1D1D1D, 16px body, and the signature move — Chivo Mono button labels on powder-blue #B2D6DE 4px-radius slabs, splitting the difference between API docs and consumer SaaS. Auth-flow UI cards and fraud dashboards do the demoing while the palette stays pastel-calm; identity infrastructure without the security-vendor menace.

Tokens

Stytch's decoded design system: background #FBFAF9, text #1D1D1D, accent #B2D6DE, link #B2D6DE, primary #0D122B; type scale h1 40px / h2 25px / body 80px; 8px spacing base; 4px base radius. The single interactive/action color is #B2D6DE — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Stytch — Design System

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

Stytch keeps auth friendly: Booton at a compact 40px/700 in warm ink #1D1D1D, 16px body, and the signature move — Chivo Mono button labels on powder-blue #B2D6DE 4px-radius slabs, splitting the difference between API docs and consumer SaaS. Auth-flow UI cards and fraud dashboards do the demoing while the palette stays pastel-calm; identity infrastructure without the security-vendor menace.

## Colors

| Role | Value |
|------|-------|
| bg | `#FBFAF9` |
| surface | `#EDECEB` |
| border | `#D9D8D8` |
| text | `#1D1D1D` |
| text_muted | `#717070` |
| primary | `#0D122B` |
| accent | `#B2D6DE` |
| link | `#B2D6DE` |
| secondary | `#E6FD13` |
| button_bg | `#B2D6DE` |
| button_text | `#1D1D1D` |

**Using these colors**

- **Action color** `#B2D6DE` — 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`, `button_bg` are all `#B2D6DE` — one role, not several (your action color).
- **accent** `#B2D6DE` — 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** `#0D122B` — a brand color — but the call-to-action uses #B2D6DE, not this.
- **secondary** `#E6FD13` — 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): `#969695` 51.8% · `#FFFFFF` 29.9% · `#707074` 10.8% · `#E3E4E6` 7.6%

## Typography

- Heading: **Whitney-Book** _(free fallback: Newsreader)_
- Body: **Whitney-Book** _(free fallback: Newsreader)_
- Mono: **Chivo Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 700 · lh 80px · tracking -2px |
| h2 | 40px / 700 · lh 40px |
| h3 | 25px / 700 · lh 30px |
| body | 16px / 400 · lh 22px |
| small | 14px / 600 · lh 21px |

- Weight ladder: 400 · 469 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Whitney-Book may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 16px, 24px, 32px, 40px, 48px — snap all gaps/padding to these

## Radius
- base: 4px
- button: 4px
- card: 4px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#B2D6DE` / `#1D1D1D` | none | 4px | 12px 12px 12px 12px | 400 13px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#1D1D1D` | 1px solid rgb(206, 206, 206) | 4px | 12px 12px 12px 12px | 400 13px | none |

**States (measured, not guessed)**

- primary hover: background `#9AC2CB`

## Motion
- durations: 300ms (dominant) · 150ms
- easings: `cubic-bezier(0.165, 0.84, 0.44, 1)` (dominant) · `cubic-bezier(0.87, 0, 0.13, 1)`
- animated properties: transform

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

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--font-booton` | `"Booton","Booton Fallback"` |
| `--font-booton-uncommon` | `"BootonUncommon","BootonUncommon Fallback"` |
| `--truste-box-overlay-inner-height` | `854px` |
| `--truste-box-overlay-height` | `854px` |
| `--truste-popframe-height` | `854px` |

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

## Layout (measured)
- container max 1200px
- nav: 100px fixed · bg #FBFAF9

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 137 | 501 | — | — | 0/0 | — |
| 638 | 184 | — | — | 0/0 | — |
| 822 | 1352 | — | — | 0/0 | — |

| 3418 | 608 | — | — | 0/0 | — |
| 4026 | 545 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.sc-548bf5a4-3` @0ms → `div.rfm-marquee`×4 @1802ms
- scroll reveal: 26 elements rest at opacity 0, translateY(86px), animate in over 200ms (7 revealed during the drive).
- 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.

## Responsive (measured)
- breakpoints: 768px · 1023px
- mobile (390px): hero 30px · 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.
