Craft writes its own pitch in Klim's Untitled pair: Untitled Serif at 66px/400 in near-black on cream #FCF9F7 for 'Your space for notes, tasks, and big ideas', Untitled Sans on full-pill ink buttons, body at 16-24px. Documents rendered as beautiful artifacts float through every section — a notes app arguing, in book typography, that your writing deserves this.

Tokens

Craft's decoded design system: background #FCF9F7, text #030302, accent #030302, link #FF3B30, primary #9BD8A9; type scale h1 66px / h2 54px / body 16px; 4px spacing base; 6px base radius. The single interactive/action color is #030302 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Craft — Design System

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

Craft writes its own pitch in Klim's Untitled pair: Untitled Serif at 66px/400 in near-black on cream #FCF9F7 for 'Your space for notes, tasks, and big ideas', Untitled Sans on full-pill ink buttons, body at 16-24px. Documents rendered as beautiful artifacts float through every section — a notes app arguing, in book typography, that your writing deserves this.

## Colors

| Role | Value |
|------|-------|
| bg | `#FCF9F7` |
| surface | `#EDEAE8` |
| border | `#D6D4D2` |
| text | `#030302` |
| text_muted | `#61605F` |
| primary | `#9BD8A9` |
| accent | `#030302` |
| link | `#FF3B30` |
| secondary | `#3C82F7` |
| button_bg | `#030302` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#030302` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#030302` — one role, not several (your action color).
- **accent** `#030302` — 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** `#9BD8A9` — a brand color — but the call-to-action uses #030302, not this.
- **link** `#FF3B30` — inline text links and link-styled controls.
- **secondary** `#3C82F7` — 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): `#F7F7F8` 37.9% · `#A1D6EF` 25.3% · `#C1DBE4` 13.9% · `#A5C6D9` 8.1%

## Typography

- Heading: **Untitled Serif** _(free fallback: Newsreader)_
- Body: **Untitled Sans** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 66px / 400 · lh 66px · tracking -1.98px |
| h2 | 54px / 400 · lh 59px · tracking -1.08px |
| h3 | 46px / 400 · lh 56px · tracking -1.38px |
| body | 24px / 400 · lh 29px · tracking -0.72px |
| small | 20px / 400 · lh 28px · tracking -0.6px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 3px, 4px, 5px, 8px, 10px, 12px, 16px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 60px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 9999px
- card: 24px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#030302` / `#FFFFFF` | none | 3.35544e+07px | 8px 14px 8px 14px | 500 16px | rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, 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 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px |
| secondary | `rgba(0, 0, 0, 0)` / `#030302` | none | 3.35544e+07px | 16px 32px 16px 32px | 500 16px | none |

**States (measured, not guessed)**

- primary hover: background `rgba(3, 3, 2, 0.75)`
- primary focus: outline `1px auto oklab(0.0959089 -0.00155481 0.00499368 / 0.0607843)`
- transition: `all 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- button: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, 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 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`
- overlay: `rgba(0, 0, 0, 0.01) 0px 50px 40px 0px, rgba(0, 0, 0, 0.02) 0px 50px 40px 0px, rgba(0, 0, 0, 0.05) 0px 20px 40px 0px, rgba(0, 0, 0, 0.08) 0px 3px 10px 0px`

## Motion
- durations: 150ms (dominant) · 200ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0, 0, 0.2, 1)`
- animated properties: color, background-color, border-color, outline-color

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

_…and 108 more measured on the page._

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

## Layout (measured)
- container max 1080px · common grid: 5-col
- nav: 52px fixed · backdrop blur(4px)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 943 | 379 | 5 | 80 | 60/60 | — |
| 4527 | 334 | 4 | 8 | 60/60 | — |

## Motion choreography (measured)
Load order: `a.sticky` @0ms → `div.relative` @831ms → `div.relative` @832ms

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

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 48px · 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.
