Tokens

Replit's decoded design system: background #FAF6F1, text #2F3034, accent #FF3C00, link #FF3C00, primary #2492FF; type scale h1 64px / h2 60px / body 28px; 4px spacing base; 8px base radius. The single interactive/action color is #FF3C00 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FF3C00 — the single interactive color; only on things you click or must notice, never large fills.
• accent, link, button_bg are all #FF3C00 — one role, not several (the action color).
• accent #FF3C00 — 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 #2492FF — a brand color — but the call-to-action uses #FF3C00, not this.
• secondary #FFB199 — 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.

# Replit — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FAF6F1` |
| surface | `#EDEAE5` |
| border | `#DBD8D4` |
| text | `#2F3034` |
| text_muted | `#7C7B7B` |
| primary | `#2492FF` |
| accent | `#FF3C00` |
| link | `#FF3C00` |
| secondary | `#FFB199` |
| button_bg | `#FF3C00` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#FF3C00` — 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 `#FF3C00` — one role, not several (your action color).
- **accent** `#FF3C00` — 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** `#2492FF` — a brand color — but the call-to-action uses #FF3C00, not this.
- **secondary** `#FFB199` — 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): `#FAF6F1` 96.9% · `#BFB4B0` 3.1%

## Typography

- Heading: **ABC Diatype** _(free fallback: Space Grotesk)_
- Body: **ABC Diatype** _(free fallback: Space Grotesk)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 69px / 400 · lh 69px · tracking -4.14px |
| h2 | 64px / 400 · lh 64px · tracking -3.84px |
| h3 | 60px / 400 · lh 53px · tracking -3px |
| body | 16px / 400 · lh 22px · tracking -0.48px |
| small | 15px / 400 · lh 12px · tracking -0.15px |

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

> **Fonts —** ABC Diatype is proprietary — closest free match: Space Grotesk (Google). Load Space Grotesk; keep ABC Diatype first so licensed users still get it.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 8px, 10px, 12px, 16px, 24px, 32px, 40px, 48px — snap all gaps/padding to these
- section rhythm: 48px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 90px
- card: 50px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#FF3C00` | 1px solid rgb(255, 60, 0) | 9999px | 10px 20px 10px 20px | 500 14px / -0.28px | none |
| secondary | `#F6F5F4` / `#36373B` | none | 6px | 0px 8px 0px 8px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: background `#FF3C00` · color `#FFFFFF`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `#EDECE8` · color `#28292C`
- transition: `background-color 0.15s ease`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.02) 0px 1px 2px 0px`

## Motion
- durations: 200ms (dominant) · 120ms · 150ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: fill, background-color, color, opacity

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 |
|-------|-------|
| `--surface-background` | `#EBECED` |
| `--interactive-background` | `#FCFCFC` |
| `--interactive-background--active` | `#F0F1F2` |
| `--interactive-border` | `#C0C3C4` |

_…and 108 more measured on the page._

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

## Layout (measured)
- common grid: 4-col
- nav: 79px sticky · bg #FAF6F1

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 2175 | 820 | 4 | 12 | 120/0 | — |
| 3027 | 650 | — | — | 84/48 | — |
| 3111 | 518 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.useView-module__vOh_Ha__` @0ms → `div.useView-module__vOh_Ha__`×4 @0ms → `span.PlatformCards-module__Z0` @1ms → `div.useView-module__vOh_Ha__` @956ms → `div.useView-module__vOh_Ha__` @956ms → `div.useView-module__vOh_Ha__` @957ms
- `div.useView-module__vOh_Ha__` — opacity 0→1 — 500ms ease-out
- stagger: `div` ×4 — 100ms apart
- scroll reveal: 10 elements rest at opacity 0, translateY(32px), animate in over 500ms (4 revealed during the drive).
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0) · r 0px
  - enter: opacity from 0 · 200ms ease

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

## Components (measured)
- disabled: bg #FF3C00 · text rgba(255, 255, 255, 0.9)

## Responsive (measured)
- breakpoints: 320px · 400px · 480px · 500px · 600px · 640px
- mobile (390px): hero 32px · 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.
