## Overview

Primary visual anchor uses #1f55f1 with primary buttons, links, and interactive highlights. Typography baseline relies on Camera Plain Variable for page titles and hero headlines.

This system uses a 4px base grid with scale values 4, 6, 8, 12, 16, 20, 24, 32, 40, 48, 56, 80, 144, 160.

**Signature traits:**
- Core token rhythm: Token evidence indicates consistent color, spacing, and radius rhythm across visible UI.

## Colors

The palette uses 10 validated color tokens across 1 theme profile. Semantic roles stay attached to observed usage so generation agents can choose accents without inventing new color meaning.

**Semantic naming:**
- **surface-background** maps to `surface-base`: Role "background" is grounded by usage context "Primary page and card backgrounds".
- **content-text** maps to `text-primary`: Role "text" is grounded by usage context "Body text, headings, and primary foreground".
- **border-border** maps to `border-default`: Role "border" is grounded by usage context "Dividers, outlines, and structural borders".
- **action-primary** maps to `action-primary`: Role "primary" is grounded by usage context "Primary buttons, links, and interactive highlights".

## Typography

Typography uses Camera Plain Variable across extracted hierarchy roles. Keep hierarchy mapped to these token rows before adding decorative type styles.

Uses Camera Plain Variable throughout for a uniform feel. Weight range spans semi-bold, regular, medium. Sizes range from 14px to 60px.

### Font Roles
- **Headline Font**: Camera Plain Variable
- **Body Font**: Camera Plain Variable

### Type Scale Evidence

| Section headings and major content titles | Camera Plain Variable | 48px | 600 | 52.8px | -1.2px | Camera Plain Variable, ui-sans-serif, system-ui, sans-serif | Extracted token |
| Subsection headings | Camera Plain Variable | 36px | 600 | 39.6px | -0.9px | Camera Plain Variable, ui-sans-serif, system-ui, sans-serif | Extracted token |
| Primary body text and default content | Camera Plain Variable | 16px | 400 | 24px | normal | Camera Plain Variable, ui-sans-serif, system-ui, sans-serif | Extracted token |

| Form labels and UI labels | Camera Plain Variable | 14px | 480 | 21px | normal | Camera Plain Variable, ui-sans-serif, system-ui, sans-serif | Extracted token |

## Layout

Responsive system uses 2 breakpoint tier(s): mobile, desktop.

### Responsive Strategy
- **mobile (<= 600px)**: Constrain layout for small viewports and prioritize vertical stacking.
- **desktop (Unknown)**: Expand layout density and horizontal composition for wide viewports.

### Spacing System
| Token | Value | Px | Notes |
|------|-------|----|-------|
| xs | 4px | 4 | Extracted spacing token |
| sm | 6px | 6 | Extracted spacing token |
| md | 8px | 8 | Extracted spacing token |
| lg | 12px | 12 | Extracted spacing token |
| xl | 16px | 16 | Extracted spacing token |
| 2xl | 20px | 20 | Extracted spacing token |
| 3xl | 24px | 24 | Extracted spacing token |
| 4xl | 32px | 32 | Extracted spacing token |
| 5xl | 40px | 40 | Extracted spacing token |
| 6xl | 48px | 48 | Extracted spacing token |
| 7xl | 56px | 56 | Extracted spacing token |
| 8xl | 80px | 80 | Extracted spacing token |
| 9xl | 144px | 144 | Extracted spacing token |
| 10xl | 160px | 160 | Extracted spacing token |

## Elevation & Depth

Keep depth flat unless validated shadow or interaction evidence appears in the extraction payload. Do not invent shadows beyond this evidence boundary.

### Shadow Evidence
| Shadow Token | Layers | Details |
|--------------|--------|---------|
| n/a | 0 | No validated shadow payload |

### Interaction Signals
| Theme | Signal | Evidence |
|-------|--------|----------|
| Light | outline-style | solid |
| Light | outline-color | rgb(28, 28, 28) ; lab(0.903296 0 0) ; lab(98.2716 0 0) |
| Light | outline-width | 3px ; 2px |
| Light | outline-offset | 0px ; 2px |
| Light | transform | matrix(1, 0, 0, 1, 0, 0) ; matrix(1, 0, 0, 1, -1280, 0) ; matrix(1, 0, 0, 1, -605.388, 0) |

## Shapes

Shape language maps directly to rounded tokens. Keep component corners consistent with the role mapping below before introducing bespoke geometry.

### Radius Roles
| Token | Value | Px | Role Mapping |
|------|-------|----|--------------|
| xs | 6px | 6 | Subtle corner |
| sm | 8px | 8 | Control corner |
| md | 12px | 12 | Control corner |
| lg | 16px | 16 | Card corner |
| xl | 24px | 24 | Large surface corner |
| 2xl | 28px | 28 | Large surface corner |

### Geometry Evidence
| Radius Token | Shape | Units |
|--------------|-------|-------|
| xs | 6px | px |
| sm | 8px | px |
| md | 12px | px |
| lg | 16px | px |
| xl | 24px | px |
| 2xl | 28px | px |

## Do's and Don'ts

Guardrails protect Core token rhythm without adding unsupported visual claims.

| Do | Don't |
|----|---------|
| Do maintain consistent spacing using the base grid | Don't make unsupported claims about absent visual features |
| Do maintain WCAG AA contrast ratios (4.5:1 for normal text) | Don't mix rounded and sharp corners in the same view |
| Do use the primary color only for the single most important action per screen |  |
| Do verify evidence before writing new design-system guidance |  |

## Responsive Evidence

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <= 600px | (max-width: 600px) |
| Breakpoint 2 | Unknown | (-webkit-min-device-pixel-ratio: 2), (min-resolution: 2x) |

## Agent Prompt Guide

### Example Component Prompts
- Create button component using validated primary color role and spacing tokens.
- Create card component with mapped radius role and evidence-backed elevation.
- Create form input component using inferred typography hierarchy and border roles.

### Iteration Guide
1. Start with extracted palette and typography roles only.
2. Map spacing and radius directly from token tables before visual polish.
3. Apply component patterns one section at a time and compare against source intent.
4. Keep elevation claims tied to explicit evidence in output.
5. Iterate with smallest diffs and re-check section hierarchy after each change.
