# Systematic Illustration Atlas

## Philosophy

A disciplined illustration language for product, brand, and editorial systems where every image explains, orients, and reinforces identity through repeatable geometry rather than decorative one-offs.

### Values

- Purposeful imagery tied to user comprehension
- Repeatable brand geometry that scales across product and editorial contexts
- Accessible contrast with restrained accent moments
- Documented illustration rules that teams can reproduce

### Anti-Values

- Mascot clutter or purely ornamental scenes
- Unbounded palettes, arbitrary textures, and inconsistent stroke logic
- Illustrations that replace clear interface communication

### Visual Character

- Layered rounded-rectangle panels use 2px ink borders, 10px corner radii, and offset accent tabs to make each illustration feel like a documented system component.
- Simple vector people and objects are built from circles, capsules, and clipped arcs with a consistent 2px stroke so product scenes remain reproducible.
- Backgrounds use a quiet dot-grid and pale blueprint blocks while coral and cyan accents appear only on callouts, arrows, and active states.
- Editorial compositions combine diagram labels, numbered chips, and connector rules so imagery communicates process rather than acting as decoration.

# Systematic Illustration Atlas

## Overview

A disciplined illustration language for product, brand, and editorial systems where every image explains, orients, and reinforces identity through repeatable geometry rather than decorative one-offs.

### Values

- Purposeful imagery tied to user comprehension
- Repeatable brand geometry that scales across product and editorial contexts
- Accessible contrast with restrained accent moments
- Documented illustration rules that teams can reproduce

### Anti-Values

- Mascot clutter or purely ornamental scenes
- Unbounded palettes, arbitrary textures, and inconsistent stroke logic
- Illustrations that replace clear interface communication

### Visual Character

- Layered rounded-rectangle panels use 2px ink borders, 10px corner radii, and offset accent tabs to make each illustration feel like a documented system component.
- Simple vector people and objects are built from circles, capsules, and clipped arcs with a consistent 2px stroke so product scenes remain reproducible.
- Backgrounds use a quiet dot-grid and pale blueprint blocks while coral and cyan accents appear only on callouts, arrows, and active states.
- Editorial compositions combine diagram labels, numbered chips, and connector rules so imagery communicates process rather than acting as decoration.

## Colors

Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.

| Token | Value |
|-------|-------|
| primary | `#1E3A5F` |
| secondary | `#4F6F8F` |
| accent | `#F26D5B` |

## shadcn/ui Usage

When the target app uses shadcn/ui, copy DESIGN.md with shadcn instead of the plain DESIGN.md. It contains the same Katagami design-language source plus the shadcn/ui primitives, imports, theme variables, component recipes, and preview-shot guidance.

DESIGN.md with shadcn: `/language/en-019dddb0-3719-7613-aeb9-77ffc2ae6955/DESIGN.with-shadcn.md`.

The shadcn page also exposes optional machine-readable files for automation, but the human-facing handoff is DESIGN.md with shadcn.

Install recommended primitives with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

Use these primitives in shadcn apps:
- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Implementation rule for agents: import shadcn primitives from `@/components/ui/*`, apply the generated CSS variables first, then compose the language-specific recipes from the companion MD. Katagami remains the source of truth; shadcn names are the implementation surface.

## Do's and Don'ts

- Do Use illustrations to clarify product flows, brand promises, or editorial arguments.
- Do Limit accents to coral, cyan-blue, and small success green moments against the restrained base palette.
- Do Document shape, stroke, and label rules beside example scenes so teams can reproduce them.
- Don't Do not introduce new character styles, painterly gradients, or random decorative stickers.
- Don't Do not place text over busy imagery or rely on color alone for meaning.
- Don't Do not use large illustrations when a concise label, icon, or interface state would communicate better.

# Systematic Illustration Atlas shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019dddb0-3719-7613-aeb9-77ffc2ae6955`
Slug: `systematic-illustration-atlas`

## Intent

A disciplined illustration language for product, brand, and editorial systems where every image explains, orients, and reinforces identity through repeatable geometry rather than decorative one-offs.

## Required primitives

- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Install with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

## Token cues

Colors:

{
  "primary": "#1E3A5F",
  "secondary": "#4F6F8F",
  "accent": "#F26D5B",
  "background": "#F7F3EA",
  "surface": "#FFFFFF",
  "text": "#17202A",
  "muted": "#6C7A86",
  "border": "#24364B",
  "error": "#B42318",
  "success": "#2F7D57",
  "warning": "#B7791F",
  "info": "#2D6CDF"
}

Typography:

{
  "heading_font": "Fraunces",
  "body_font": "Source Sans 3",
  "mono_font": "IBM Plex Mono",
  "base_size": "16px",
  "scale_ratio": 1.25,
  "line_height": 1.55,
  "letter_spacing": "-0.015em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Fraunces:opsz,wght@9..144,600;9..144,700&family=IBM+Plex+Mono:wght@500;600&family=Source+Sans+3:wght@400;500;600;700&display=swap"
}

## Visual character to preserve

- Layered rounded-rectangle panels use 2px ink borders, 10px corner radii, and offset accent tabs to make each illustration feel like a documented system component.
- Simple vector people and objects are built from circles, capsules, and clipped arcs with a consistent 2px stroke so product scenes remain reproducible.
- Backgrounds use a quiet dot-grid and pale blueprint blocks while coral and cyan accents appear only on callouts, arrows, and active states.
- Editorial compositions combine diagram labels, numbered chips, and connector rules so imagery communicates process rather than acting as decoration.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "stickerBadges": false,
  "motion": "lift",
  "density": "balanced",
  "accents": [
    "primary",
    "accent",
    "secondary",
    "muted"
  ]
}

## Signature component recipes

### Button
Use `Button` for primary, secondary, outline, and ghost actions. Primary actions must expose the language's strongest contrast pair, while secondary and ghost actions should preserve the surface treatment instead of falling back to default neutral SaaS styling.

### Card
Use `Card`, `CardHeader`, `CardContent`, `CardFooter`, and `CardAction` as the main composition frame. Cards should demonstrate the language's surface, border, hierarchy, and density rules rather than appearing as generic rounded rectangles.

### Input and Textarea
Use `Input` and `Textarea` with visible focus rings, field labels, validation states, and the language's rhythm. Forms should show real product content, not placeholder-only controls.

### Select, Tabs, and Table
Use `Select`, `Tabs`, and `Table` to prove navigation, filtering, and dense data states. The table should show row rhythm, separators, hover/focus states, and an empty or status state when the language calls for it.

### Dialog and Sheet
Use `Dialog` for centered decisions and `Sheet` for contextual editing. Both should inherit the language's spacing, border, overlay, and motion rules.

## Preview shots

- `application-shell`: dashboard or workspace shell with navigation, cards, forms, and state badges.
- `detail-editor`: focused editing flow using input, textarea, select, switch/checkbox, dialog or sheet, and action buttons.
- `data-operations`: table-heavy operational view with tabs, dropdown menu affordances, badges, and destructive/empty states.
- Each preview shot must include a renderable `scene` payload with concrete headline, description, actions, and rows/fields/stats for the UI preview.

## Implementation contract

- Start from local `ui/src/components/ui` shadcn-style primitives; do not create a second component system.
- Apply `/katagami/shadcn/systematic-illustration-atlas/registry-theme.json` variables, then use these recipes for composition and state design.
- Preserve Katagami token names as source metadata; shadcn semantic names are only the export surface.
- Do: Use illustrations to clarify product flows, brand promises, or editorial arguments.; Limit accents to coral, cyan-blue, and small success green moments against the restrained base palette.; Document shape, stroke, and label rules beside example scenes so teams can reproduce them.
- Do not: Do not introduce new character styles, painterly gradients, or random decorative stickers.; Do not place text over busy imagery or rely on color alone for meaning.; Do not use large illustrations when a concise label, icon, or interface state would communicate better.

## Copy-paste component example

This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
