Decoded design system

Lucide's decoded design system: background #FFFFFF, text #3C3C43, accent #F56565, link #F67373, primary #F56565; type scale h1 56px / h2 32px / body 14px; 8px spacing base; 8px base radius. The single interactive/action color is #F56565 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F56565 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #F56565 — one role, not several (the action color).
• accent #F56565 — 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.
• link #F67373 — fails contrast on the background (~2.8:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #9CA3AF — 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.

# Lucide — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F3F3F3` |
| border | `#E1E1E2` |
| text | `#3C3C43` |
| text_muted | `#86868A` |
| primary | `#F56565` |
| accent | `#F56565` |
| link | `#F67373` |
| secondary | `#9CA3AF` |
| button_bg | `#F56565` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#F56565` — 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`, `button_bg` are all `#F56565` — one role, not several (your action color).
- **accent** `#F56565` — 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.
- **link** `#F67373` — fails contrast on the background (~2.8:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#9CA3AF` — 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): `#FFFFFF` 95.6% · `#D3C2C4` 4.4%

## Typography

- Heading: **Inter**
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 56px / 700 · lh 64px · tracking -0.4px |
| h2 | 32px / 700 · lh 24px |
| h3 | 24px / 500 · lh 36px |
| body | 14px / 500 · lh 24px |
| small | 13px / 600 · lh 20px |

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

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 3px, 4px, 6px, 8px, 11px, 12px, 16px, 20px, 24px — snap all gaps/padding to these

## Radius
- base: 8px
- button: 20px
- card: 6px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F56565` / `#FFFFFF` | 1px solid rgba(0, 0, 0, 0) | 20px | 0px 20px 0px 20px | 600 14px | none |
| secondary | `#EBEBEF` / `#3C3C43` | 1px solid rgba(0, 0, 0, 0) | 20px | 0px 20px 0px 20px | 600 14px | none |

**States (measured, not guessed)**

- primary hover: background `#FF7070`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `#E4E4E9`
- transition: `color 0.25s ease`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.1) 0px 12px 32px 0px, rgba(0, 0, 0, 0.08) 0px 2px 6px 0px`
- overlay: `rgba(0, 0, 0, 0.12) 0px 14px 44px 0px, rgba(0, 0, 0, 0.12) 0px 3px 9px 0px`

## Motion
- durations: 250ms (dominant) · 500ms · 150ms
- easings: `ease` (dominant) · `ease-in`
- animated properties: color, background-color, border-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 |
|-------|-------|
| `--vp-c-white` | `#ffffff` |
| `--vp-c-black` | `#000000` |
| `--vp-c-neutral` | `#000000` |
| `--vp-c-neutral-inverse` | `#ffffff` |
| `--vp-c-gray-1` | `#dddde3` |
| `--vp-c-gray-2` | `#e4e4e9` |
| `--vp-c-gray-3` | `#ebebef` |
| `--vp-c-gray-soft` | `rgba(142, 150, 170, .14)` |
| `--vp-c-indigo-1` | `#3451b2` |
| `--vp-c-indigo-2` | `#3a5ccc` |
| `--vp-c-indigo-3` | `#5672cd` |
| `--vp-c-indigo-soft` | `rgba(100, 108, 255, .14)` |

_…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: 3-col
- nav: 64px fixed

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 1738 | 334 | 3 | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.VPNavBar` @0ms → `div.divider-line` @0ms → `a.badge` @178ms → `a.badge` @178ms → `div` @247ms
- `div` — opacity 0→1 — 400ms ease-out
- `a.badge` — color rgba(0, 0, 0, 0)→rgba(0, 0, 0, 0) — 5000ms cubic-bezier(0.22, 1, 0.36, 1) (delay 500ms) · loops

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

## Themes (both measured)
- dark counterpart: bg `#1B1B1F` · text `#DFDFD6`
- tokens that flip between modes:
  - `--vp-c-neutral`: `#000000` → `#ffffff`
  - `--vp-c-neutral-inverse`: `#ffffff` → `#000000`
  - `--vp-c-gray-1`: `#dddde3` → `#515c67`
  - `--vp-c-gray-2`: `#e4e4e9` → `#414853`
  - `--vp-c-gray-3`: `#ebebef` → `#32363f`
  - `--vp-c-gray-soft`: `rgba(142, 150, 170, .14)` → `rgba(101, 117, 133, .16)`
  - `--vp-c-indigo-1`: `#3451b2` → `#a8b1ff`
  - `--vp-c-indigo-2`: `#3a5ccc` → `#5c73e7`

## Responsive (measured)
- breakpoints: 480px · 640px · 768px · 960px · 1152px · 1280px
- mobile (390px): 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.
