do
  • Make every decorative pixel also explain state, progress, selection, or reward.
  • Use one committed rounded-square radius scale across panels, controls, badges, and mascot tiles.
  • Keep body text highly legible and reserve pixel typography for short collectible labels.
  • Design complete product scenes for children and teachers with real tasks, rows, controls, and states.
avoid
  • Do not use black terminal surfaces, neon cyberpunk palettes, or harsh retro arcade contrast.
  • Do not scatter random pixels as decoration without a grid or state purpose.
  • Do not mix pill blobs, sharp squares, and arbitrary plush radii in the same screen.
  • Do not let mascot illustration replace navigation, forms, tables, or responsive product structure.

# Badge Buddy Sprite Club

## Philosophy

A kid-friendly product language for classroom quests, sticker collections, and mascot-led learning dashboards where pixel art becomes a soft system of rounded square tiles, expressive sprite faces, and collectible badge states rather than hard retro nostalgia.

### Values

- gentle primary color confidence
- friendly sprite character without childish clutter
- collectible progress clarity
- rounded-square pixel discipline
- accessible learning-product warmth

### Anti-Values

- sharp arcade austerity or black CRT nostalgia
- random sticker overload that hides hierarchy
- mixed arbitrary radii that make the system generically plush
- pixel fonts used for paragraphs or complex instructions

### Visual Character

- Every panel and control is built from an 8px bitmap grid with 14px rounded-square corners, visible tile seams, and stepped corner notches instead of generic cards.
- Mascot expressions are composed from tiny rounded square eyes, blush pixels, and mouth tiles that live inside badges, empty states, and progress confirmations.
- Soft primary color blocks sit on a warm cream canvas with thick blueberry outlines, small offset candy shadows, and no gradients or glass effects.
- Collectible badges use layered square-pixel medallions, ribbon tabs, and count chips so rewards, status, and navigation share one reusable object grammar.
- Dense information is grouped into playful tilesets: lesson rows, inventory slots, and progress maps snap to fixed pixel cells while body copy stays spacious and readable.

### Hierarchy

Use Baloo 2 for rounded chunky headings, Atkinson Hyperlegible for all learning copy, and Pixelify Sans only for compact counters, map coordinates, and badge codes.

### Signature Patterns

- Use CSS grid tracks sized in 8px multiples to create rounded square pixel tiles, inventory slots, and progress maps with consistent cell seams.
- Build mascot faces from CSS variables and tiny rounded square pseudo-elements so expressions can appear on cards, badges, and empty states.
- Attach stepped pixel tabs to selected cards with box-shadow offsets and square sub-pixels rather than gradients, ribbons, or skeuomorphic badges.
- Represent progress as collectible medallion stacks with count chips, ribbon tabs, and completion stamps sharing the same blueberry outline geometry.

## Layout

### Breakpoints

mobile 375px, tablet 768px, desktop 1440px

### Grid

Desktop uses a 12-column layout over an 8px baseline with a 7-column quest-board hero, 3-column guidance rail, and 2-column badge tray; tablet and mobile stack the hero first.

### Whitespace

Use 32px to 48px outside padding on desktop, 24px on tablet, and 16px on mobile; preserve 8px seams inside tile clusters and 16px gaps between badges.

## Guidance

### Do

- Make every decorative pixel also explain state, progress, selection, or reward.
- Use one committed rounded-square radius scale across panels, controls, badges, and mascot tiles.
- Keep body text highly legible and reserve pixel typography for short collectible labels.
- Design complete product scenes for children and teachers with real tasks, rows, controls, and states.

# Badge Buddy Sprite Club

## Overview

A kid-friendly product language for classroom quests, sticker collections, and mascot-led learning dashboards where pixel art becomes a soft system of rounded square tiles, expressive sprite faces, and collectible badge states rather than hard retro nostalgia.

### Values

- gentle primary color confidence
- friendly sprite character without childish clutter
- collectible progress clarity
- rounded-square pixel discipline
- accessible learning-product warmth

### Anti-Values

- sharp arcade austerity or black CRT nostalgia
- random sticker overload that hides hierarchy
- mixed arbitrary radii that make the system generically plush
- pixel fonts used for paragraphs or complex instructions

### Visual Character

- Every panel and control is built from an 8px bitmap grid with 14px rounded-square corners, visible tile seams, and stepped corner notches instead of generic cards.
- Mascot expressions are composed from tiny rounded square eyes, blush pixels, and mouth tiles that live inside badges, empty states, and progress confirmations.
- Soft primary color blocks sit on a warm cream canvas with thick blueberry outlines, small offset candy shadows, and no gradients or glass effects.
- Collectible badges use layered square-pixel medallions, ribbon tabs, and count chips so rewards, status, and navigation share one reusable object grammar.
- Dense information is grouped into playful tilesets: lesson rows, inventory slots, and progress maps snap to fixed pixel cells while body copy stays spacious and readable.

## 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-019e66f7-7edc-7102-9258-d94ed8b0be0f/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.

# Badge Buddy Sprite Club shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e66f7-7edc-7102-9258-d94ed8b0be0f`
Slug: `badge-buddy-sprite-club`

## Intent

A kid-friendly product language for classroom quests, sticker collections, and mascot-led learning dashboards where pixel art becomes a soft system of rounded square tiles, expressive sprite faces, and collectible badge states rather than hard retro nostalgia.

## 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:

{
  "accent": "#FF7AA8",
  "background": "#FFF7E8",
  "border": "#2F4F9C",
  "error": "#E65353",
  "info": "#5BC7E8",
  "muted": "#7280A8",
  "primary": "#4F7CFF",
  "secondary": "#FFCF4A",
  "success": "#42B883",
  "surface": "#FFFFFF",
  "text": "#26345D",
  "warning": "#F6A83B"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Atkinson Hyperlegible",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Atkinson+Hyperlegible:wght@400;700&family=Baloo+2:wght@600;700;800&family=Pixelify+Sans:wght@500;600;700&display=swap",
  "heading_font": "Baloo 2",
  "letter_spacing": "-0.01em",
  "line_height": 1.5,
  "mono_font": "Pixelify Sans",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Every panel and control is built from an 8px bitmap grid with 14px rounded-square corners, visible tile seams, and stepped corner notches instead of generic cards.
- Mascot expressions are composed from tiny rounded square eyes, blush pixels, and mouth tiles that live inside badges, empty states, and progress confirmations.
- Soft primary color blocks sit on a warm cream canvas with thick blueberry outlines, small offset candy shadows, and no gradients or glass effects.
- Collectible badges use layered square-pixel medallions, ribbon tabs, and count chips so rewards, status, and navigation share one reusable object grammar.
- Dense information is grouped into playful tilesets: lesson rows, inventory slots, and progress maps snap to fixed pixel cells while body copy stays spacious and readable.

  ]
}

## 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/badge-buddy-sprite-club/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: Make every decorative pixel also explain state, progress, selection, or reward.; Use one committed rounded-square radius scale across panels, controls, badges, and mascot tiles.; Keep body text highly legible and reserve pixel typography for short collectible labels.; Design complete product scenes for children and teachers with real tasks, rows, controls, and states.
- Do not: Do not use black terminal surfaces, neon cyberpunk palettes, or harsh retro arcade contrast.; Do not scatter random pixels as decoration without a grid or state purpose.; Do not mix pill blobs, sharp squares, and arbitrary plush radii in the same screen.; Do not let mascot illustration replace navigation, forms, tables, or responsive product structure.

## Copy-paste component example

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