Decoded design system

Gumroad's decoded design system: background #F4F4F0, text #000000, accent #FF90E8, link #FFFFFF, primary #FF90E8; type scale h1 192px / h2 96px / body 18px; 8px spacing base; 6px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Gumroad — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#F4F4F0` |
| surface | `#E5E5E1` |
| border | `#CFCFCC` |
| text | `#000000` |
| text_muted | `#5C5C5B` |
| primary | `#FF90E8` |
| accent | `#FF90E8` |
| link | `#FFFFFF` |
| secondary | `#625BF6` |
| button_bg | `#000000` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#000000` — 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` are all `#FF90E8` — one role, not several.
- **accent** `#FF90E8` — accent for emphasis — keep it rare on the page.
- **link** `#FFFFFF` — fails contrast on the background (~1.1:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#625BF6` — 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): `#F4F4F0` 81.3% · `#D9AFD4` 10.8% · `#483846` 7.9%

## Typography

- Heading: **ABC Favorit** _(free fallback: Newsreader)_
- Body: **Arial**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 192px / 500 · lh 173px · tracking -0.4px |
| h2 | 96px / 400 · lh 96px · tracking -0.4px |
| h3 | 72px / 400 · lh 72px · tracking -0.4px |
| body | 18px / 400 · lh 28px · tracking -0.4px |
| small | 16px / 400 · lh 24px · tracking -0.4px |

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

> **Fonts —** ABC Favorit may be proprietary — safe free fallback: Newsreader (Google Fonts). Arial — system font, no web load needed.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 12px, 16px, 24px, 32px, 40px, 48px, 58px — snap all gaps/padding to these

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

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#000000` / `#FFFFFF` | 1px solid rgb(0, 0, 0) | 4px | 0px 40px 0px 40px | 400 20px / -0.4px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#000000` | 1px solid rgb(0, 0, 0) | 3.35544e+07px | 6px 6px 6px 6px | 400 16px / -0.4px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `oklch(0.967 0.003 264.542)`
- transition: `all 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 200ms · 100ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `linear`
- animated properties: transform, translate, scale, rotate

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 |
|-------|-------|
| `--color-purple-200` | `oklch(90.2% .063 306.703)` |

| `--pink` | `#ff90e8` |

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

## Layout (measured)
- container max 768px · common grid: 2-col
- nav: 776px · bg #F4F4F0

## Motion choreography (measured)
Load order: `div.absolute` @0ms → `div.flex`×3 @86ms

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

## Components (measured)
- input: h 64px · r 4px · border 1px solid rgb(36, 36, 35) · bg #F4F4F0 · placeholder #757575
  - focus ring: `` — this exact construction, don't invent your own
- link: #FFFFFF · no underline

## Themes (both measured)
- dark counterpart: bg `#242423` · text `#DDDDDD`
- tokens that flip between modes:
  - `--active-bg`: `rgb(255 255 255)` → `rgb(0 0 0)`
  - `--color-primary-foreground`: `rgb(255 255 255)` → `rgb(0 0 0)`
  - `--color-active-bg`: `rgb(0 0 0/.1)` → `rgb(221 221 221/.1)`
  - `--body-bg`: `#f4f4f0` → `#242423`
  - `--color-background`: `rgb(255 255 255)` → `rgb(0 0 0)`
  - `--color-body`: `#f4f4f0` → `#242423`
  - `--color-muted`: `rgb(0 0 0/.5)` → `rgb(221 221 221/.5)`
  - `--color-primary`: `rgb(0 0 0)` → `rgb(221 221 221)`

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 60px · 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.
