## 1. System Overview

**Design Language:** Risograph Print
**Mode:** Light
**Typefaces:** Space Grotesk + Work Sans
**Personality:** Riso duplicator output: warm paper, ink blue and fluorescent pink drums, visible misregistration and grain.
**Best Suited For:** Indie publishers, art prints, creative studio sites, event programmes, small-press shops

**Core Principles:**
- Two inks only: blue and pink over warm paper.
- Misregistration is a feature: offsets sit a few pixels off.
- No solid black; the deepest tone is the blue drum.
- Space Grotesk headlines, Work Sans body.

## 2. CSS Custom Properties - Master Token Sheet

All tokens are scoped under `[data-ds="risograph-print"]`. Nothing is defined at `:root`. The same sheet ships as `tokens.css` in this system's folder.

```css
/*
 * Risograph Print - scoped design-system tokens (Theme 25 in catalog).

## 3. Color Palette

### 3.1 Core Colors

|Role|Token|Value|Usage|
|---|---|---|---|
|bg-base|`--ds-color-bg-base`|`#f4f1ea`|Warm paper|
|bg-surface|`--ds-color-bg-surface`|`#fbf9f3`|Cards and panels|
|bg-sunken|`--ds-color-bg-sunken`|`#e9e5da`|Inputs, wells|
|primary|`--ds-color-primary`|`#ff48b0`|Blue drum action|
|secondary-bg|`--ds-btn-secondary-bg`|`#0078bf`|Pink drum secondary|
|text-primary|`--ds-color-text-primary`|`#1d1d1b`|Blue ink text|
|text-secondary|`--ds-color-text-secondary`|`#3c3c38`|Supporting ink|

### 3.2 Semantic Colors

|State|Token|Ink|Background|
|---|---|---|---|
|success|`--ds-color-success`|`#1b7441`|`#d7f2e0`|
|warning|`--ds-color-warning`|`#8a5700`|`#fff0cc`|
|error|`--ds-color-error`|`#c0262d`|`#fde3e4`|
|info|`--ds-color-info`|`#005a8f`|`#d8ecfa`|

### 3.3 Contrast Checks

- Body text `#1e2b6b` on paper `#fdf8ee`: 10.8:1.
- Pink `#ff5c8a` is a fill with paper or blue foregrounds, never body text on paper.
- Overprints (blue over pink) pass as decorative shapes; text never sits on the overlap.

## 4. Typography System

### 4.1 Font Families

|Role|Family|Usage|
|---|---|---|
|Display|Space Grotesk|Headings, hero titles|
|Body|Work Sans|Body copy, form fields|
|Label|Work Sans|Buttons, badges, labels|

### 4.2 Type Scale


| Token | Size | Weight | Tracking | Use |
|---|---|---|---|---|
| Display | 48-64px | 400 | 0 | Hero title |
| H1 | 36px | 400 | 0 | Page title |
| H2 | 28px | 400 | 0 | Section title |
| H3 | 20px | 400 | 0 | Card title |
| Body | 16px | 400 | 0 | Paragraphs |
| Label | 13px | 700 | 0.01em | Buttons, badges |

Lilita One ships in a single weight (400). Its drawn strokes are already heavy - never synthesise a bolder weight.

### 4.3 Google Fonts Import Block

Fonts load through the shared `DESIGN_SYSTEM_FONTS_URL` in `app/design-systems/fonts.ts`. Never `@import` a remote font URL from CSS; the production bundler drops it.

---

## 5. Spacing System


Base unit: 4px. Use only these steps.

| Token | Value |
|---|---|
| space-1 | 4px |
| space-2 | 8px |
| space-3 | 12px |
| space-4 | 16px |
| space-6 | 24px |
| space-8 | 32px |
| space-12 | 48px |
| space-16 | 64px |

Component padding: card 22px, button 11px 22px (md), input 11px 14px, badge 3px 12px.

---

## 6. Border Radius System

|Token|Value|
|---|---|
|badge|`2px`|
|sm|`2px`|
|md|`2px`|
|lg|`2px`|
|xl|`4px`|
|full|`9999px`|

Small 6px corners, like trimmed prints; badges may round fully.

---

## 7. Shadow & Elevation System

|Token|Value|
|---|---|
|card|`6px 6px 0 #0078bf`|
|dropdown|`4px 4px 0 #ff48b0`|
|modal|`8px 8px 0 #0078bf`|
|focus|`3px 3px 0 #0078bf`|
|btn-hover|`4px 4px 0 #0078bf`|

---

| Fast | 0ms |
| Base | 120ms |

---

---

## 11. Z-Index System


| Layer | Value |
|---|---|
| Base | 0 |
| Sticky header | 10 |
| Dropdown | 20 |
| Modal backdrop | 40 |

## 12. Breakpoints


| Name | Min width |
|---|---|
| sm | 640px |

| xl | 1280px |

Page padding: 16px below md, 24px at md, 32px at lg and up.

---

---

## 13. Icon System

Icons use 2px strokes; duotone pairs render the same icon offset in blue and pink. Sizes follow the shared scale: 16px inline, 20px in buttons, 24px standalone.

---

## 14. State Definitions

- Hover uses the `--ds-color-primary-hover` and `--ds-shadow-btn-hover` tokens.
- Active applies `--ds-btn-active-transform` and the `--ds-color-primary-active` tone.
- Focus always renders `--ds-focus-ring`; never remove it without a visible replacement.
- Disabled drops to 50% opacity with `not-allowed` cursor and no shadow.
