Decoded design system

Napkin's decoded design system: background #FFFFFF, text #1A1A1A, accent #2D68F5, link #969696, primary #2D68F5; type scale h1 80px / h2 44px / body 18px; 8px spacing base; 8px base radius. The single interactive/action color is #484848 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #484848 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #2D68F5 — one role, not several (the action color).
• accent #2D68F5 — accent for emphasis — keep it rare on the page.
• link #969696 — fails contrast on the background (~3.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #EAF1FF — 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.

# Napkin — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DCDCDC` |
| text | `#1A1A1A` |
| text_muted | `#717171` |
| primary | `#2D68F5` |
| accent | `#2D68F5` |
| link | `#969696` |
| secondary | `#EAF1FF` |
| button_bg | `#484848` |
| button_text | `#F7F7F7` |

**Using these colors**

- **Action color** `#484848` — 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 `#2D68F5` — one role, not several.
- **accent** `#2D68F5` — accent for emphasis — keep it rare on the page.
- **link** `#969696` — fails contrast on the background (~3.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#EAF1FF` — 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` 84% · `#D2F5FF` 5.1% · `#807F82` 4.5% · `#C7DBE2` 3.7%

## Typography

- Heading: **Geomanist** _(free fallback: Newsreader)_
- Body: **Plus Jakarta Sans**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 700 · lh 85px |
| h2 | 44px / 700 · lh 44px |
| h3 | 30px / 400 · lh 46px |
| body | 18px / 400 · lh 24px |
| small | 16px / 600 · lh 30px |
| eyebrow | 9px / 800 · tracking 0.45px |

- Weight ladder: 400 · 500 · 600 · 700 · 800 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Geomanist may be proprietary — safe free fallback: Newsreader (Google Fonts). Plus Jakarta Sans — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 7px, 10px, 12px, 13px, 16px, 20px, 21px, 26px, 33px, 35px — snap all gaps/padding to these
- section rhythm: 85px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 8px
- card: 16px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#484848` / `#F7F7F7` | none | 8px | 16px 26px 16px 26px | 400 18px | none |
| secondary | `#484848` / `#FFFFFF` | 1px solid rgb(72, 72, 72) | 6.4px | 6.56px 13.12px 6.56px 13.12px | 600 13.12px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `background-color 0.5s ease-out`

## Shadows (elevation)
- card: `rgba(0, 0, 2, 0.3) 0px 10px 30px 0px`
- overlay: `rgba(133, 147, 103, 0.2) 0px 4px 48px 0px`

## Motion
- durations: 500ms (dominant) · 150ms · 250ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: color, background-color, border-color, transform

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

_…and 32 more measured on the page._

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

## Layout (measured)
- container max 1280px
- nav: 137px · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|

## Motion choreography (measured)
Load order: `span.hero__title-line-highlig` @0ms → `span.hero__title-line-highlig` @690ms → `div.cm--box` @781ms → `div.cm--box` @781ms → `div.cm--box` @781ms → `h1.hero__title` @1054ms
- `h1.hero__title` — opacity 0→0.4 · width 0px→11px — 500ms ease-in-out (delay 1410ms)
- `h1.hero__title` — opacity 0→1 — 500ms ease-out (delay 1510ms)
- `h1.hero__title` — transform translateY(-50%) scale(1)→translateY(-50%) scale(1.1) · filter contrast(1)→contrast(1) — 300ms ease-out (delay 2010ms)
- scroll reveal: 2 elements rest at opacity 0, animate in over 500ms (0 revealed during the drive).
- overlay dialog (auto-opened): panel #FFFFFF · r 8px · shadow rgba(0, 0, 2, 0.3) 0px 10px 30px 0px

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

## Responsive (measured)
- breakpoints: 350px · 400px · 450px · 550px · 640px · 650px
- mobile (390px): hero 32px · 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.
