Decoded design system

Beehiiv's decoded design system: background #FFFFFF, text #060419, accent #060419, link #FFFFFF, primary #131125; type scale h1 60px / h2 48px / body 20px; 8px spacing base; 8px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
• link, button_bg are all #FFFFFF — one role, not several (the action color).
• accent #060419 — accent for emphasis — keep it rare on the page.
• primary #131125 — a brand color — but the call-to-action uses #FFFFFF, not this.
• secondary #C4C2D6 — 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.

# Beehiiv — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0EFF1` |
| border | `#D9D9DC` |
| text | `#060419` |
| text_muted | `#646370` |
| primary | `#131125` |
| accent | `#060419` |
| link | `#FFFFFF` |
| secondary | `#C4C2D6` |
| button_bg | `#FFFFFF` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `link`, `button_bg` are all `#FFFFFF` — one role, not several (your action color).
- **accent** `#060419` — accent for emphasis — keep it rare on the page.
- **primary** `#131125` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **secondary** `#C4C2D6` — 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): `#060419` 69.2% · `#928A9C` 14.3% · `#DCD3D2` 9.8% · `#282449` 6.6%

## Typography

- Heading: **SatoshiFont** _(free fallback: Newsreader)_
- Body: **SatoshiFont** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 60px / 700 · lh 60px |
| h2 | 48px / 700 · lh 48px |
| h3 | 30px / 700 · lh 36px |
| body | 20px / 500 · lh 28px |
| small | 18px / 700 · lh 28px |
| eyebrow | 14px / 700 · tracking 1.12px |

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 10px, 12px, 16px, 20px, 24px, 32px, 40px, 64px — snap all gaps/padding to these

## Radius
- base: 8px
- button: 4px
- card: 6px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#000000` | 1px solid rgb(255, 255, 255) | 4px | 8px 24px 8px 24px | 500 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | 1px solid rgb(255, 255, 255) | 6px | 8px 24px 8px 24px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: box-shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 10px 15px -3px, rgba(0, 0, 0, 0.1) 0px 4px 6px -4px` · background `#060419` · color `#FFFFFF`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `#FFFFFF` · color `#060419`
- transition: `all 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 4px 6px -1px, rgba(0, 0, 0, 0.1) 0px 2px 4px -2px`

## Motion
- durations: 125ms (dominant) · 300ms · 200ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease-out`
- animated properties: transform, color, background-color, border-color

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)

_…and 42 more measured on the page._

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

## Layout (measured)
- container max 1180px

## Motion choreography (measured)
Load order: `div.trusted-newsletters-trac` @0ms → `div.ticker-image-container`×4 @1ms → `div.ticker-image-container`×2 @1ms → `div.animate-fadeIn` @858ms
- `div.animate-fadeIn` — opacity 0→1 — 300ms ease-in-out
- scroll reveal: 4 elements rest at opacity 0, translateY(64px), animate in over 0.5s cubic-bezier(0.4, 0, 0.2, 1) (0 revealed during the drive).

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

## Components (measured)
- card ×3: pad 24px 24px 24px 24px · r 8px · border 1px solid rgb(21, 25, 79) · shadow rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 4px 6px -1px, rgba(0, 0, 0, 0.1) 0px 2px 4px -2px · bg rgba(0, 0, 0, 0)
  - hover: font-weight `400` · letter-spacing `normal`

## Responsive (measured)
- breakpoints: 480px · 600px · 640px · 768px · 800px · 992px
- mobile (390px): hero 42px · 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.
