rules
Use a single hero product workspace as the dominant artifact, with generous white margins, a compact top command bar, and clustered device/status cards that feel like one consumer app screen rather than a module inventory.
Medium-light density: spacious shells and cards, compact pixel metadata, and only a few high-energy highlight moments per viewport.
Large smooth headings carry the consumer promise, while pixel typography is reserved for secondary proof labels, numerals, badges, and state annotations so readability remains premium.
layout
mobile 375px, tablet 768px, desktop 1200px and up
A 12-column desktop product shell becomes two columns on tablet and a single stacked column on mobile; no visible square grid background is used.
Whitespace is the premium material: 24-48px gutters on desktop, 20-32px between major cards, and compact 8px internal pixel clusters.
guidance
- Use indigo, cyan/turquoise, and lime as a deliberately narrow cool-electric family tied to active, synced, and success states.
- Keep pixel fonts to labels, counters, badges, key hints, and display numerals while preserving smooth sans body readability.
- Make pixel elements functional: progress, sync states, selected bits, icon glyphs, and compact micro-illustrations.
- Favor neutral white product scenes, generous spacing, even borders, and one committed radius system.
- Do not use square-grid backgrounds, default dotted textures, decorative side rails, row stripes, or card accent bars.
- Do not add arcade styling, block-game references, terminal hacker tropes, excessive neon glow, or unreadable low-resolution body text.
- Do not scatter rainbow colors or warm accent garnish; reserve exceptions for required semantic warning/error states.
- Do not use chipped diagonal corners, uneven borders, arbitrary mixed radii, or generic SaaS dashboard layouts.

# Lumen Pixel Product System
## Overview
A premium consumer product UI language for calm white surfaces where pixel cues behave like precision marks: compact state bits, stepped progress chips, and pixel-influenced annotation typography set against Apple-clean layouts with cool electric indigo, cyan, turquoise, and lime highlights.
### Values
- clean consumer confidence
- pixel precision without game nostalgia
- cool-electric state clarity
- premium restraint
- tactile product usefulness
### Anti-Values
- arcade skins or Minecraft-style block overload
- rainbow accent sprawl or warm garnish
- square-grid backgrounds and decorative dotted texture
- generic SaaS dashboards with color as decoration
### Visual Character
- Use matte white and porcelain-neutral full-bleed backgrounds with large rounded panels, hairline borders, and no repeated grid or dotted texture.
- Render pixel identity through tiny stepped bit clusters, square indicator glyphs, and segmented progress sequences placed inside controls and data states.
- Pair smooth modern sans headings and body text with a pixel-influenced display face only for badges, counters, keyboard hints, and micro annotations.
- Apply indigo as the calm primary anchor, cyan/turquoise as active focus light, and lime as sparse success energy inside small state elements.
- Compose screens around one dominant product artifact: a consumer device sync workspace with object cards, command bands, and precise status modules.
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.
| Token | Value |
|-------|-------|
| accent | `#D7FF32` |
| background | `#FAFBFF` |
| border | `#DDE3F0` |
| error | `#E5484D` |
| info | `#00D5FF` |
| muted | `#6B7280` |
| primary | `#4038FF` |
| secondary | `#00BFD8` |
| success | `#7BEF2B` |
| surface | `#FFFFFF` |
| text | `#111827` |
| warning | `#F4C430` |
## Typography
- **Headline-Lg**: Instrument Sans, 1.816rem, weight 700, line-height 1.1.
- **Headline-Md**: Instrument Sans, 1.488rem, weight 600, line-height 1.15.
- **Body-Md**: Manrope, 16px, weight 400, line-height 1.52.
- **Label-Md**: Pixelify Sans, 0.75rem, weight 600, line-height 1.
## Layout
### Spacing Tokens
- **Base**: `8px`
- **Xs**: `4px`
- **Sm**: `8px`
- **Md**: `12px`
- **Lg**: `16px`
- **Xl**: `24px`
- **2xl**: `32px`
- **3xl**: `48px`
- **4xl**: `64px`
### Breakpoints
mobile 375px, tablet 768px, desktop 1200px and up
### Grid
A 12-column desktop product shell becomes two columns on tablet and a single stacked column on mobile; no visible square grid background is used.
### Whitespace
Whitespace is the premium material: 24-48px gutters on desktop, 20-32px between major cards, and compact 8px internal pixel clusters.
## Elevation & Depth
### Shadows
- **Lg**: 0 30px 80px rgba(31, 45, 90, 0.14)
- **Md**: 0 18px 45px rgba(26, 38, 80, 0.10)
- **Sm**: 0 1px 2px rgba(17, 24, 39, 0.06)
## Shapes
### Rounded
- **Full**: `9999px`
- **Lg**: `28px`
- **Md**: `16px`
- **None**: `0px`
- **Sm**: `10px`
### Surfaces
- **Bg Pattern**: no square grid and no dotted texture; use only occasional isolated pixel glyph clusters as semantic state markers
- **Card Style**: large even-radius white cards, 1px cool hairline border, soft shadow, interior pixel status bits rather than external stripes
- **Treatment**: porcelain white planes with subtle cool-blue edge light and restrained translucent command bands
### Borders
- **Accent Width**: 2px
- **Character**: even cool-gray hairlines with indigo/cyan focus rings; never uneven or chipped
- **Default Width**: 1px
- **Style**: solid
## Components
### Composition
Use a single hero product workspace as the dominant artifact, with generous white margins, a compact top command bar, and clustered device/status cards that feel like one consumer app screen rather than a module inventory.
### Density
Medium-light density: spacious shells and cards, compact pixel metadata, and only a few high-energy highlight moments per viewport.
### Hierarchy
Large smooth headings carry the consumer promise, while pixel typography is reserved for secondary proof labels, numerals, badges, and state annotations so readability remains premium.
### Signature Patterns
- Segmented pixel progress bars use 6 to 10 individual square bits that fill from indigo through cyan to sparse lime for meaningful completion states.
- Active controls use a soft cyan glow ring plus an internal two-square bit glyph instead of decorative side rails, card stripes, or large neon floods.
- Object cards include tiny pixel-font telemetry labels anchored to real data, with body content always set in the readable sans family.
- Command bands use translucent white surfaces over the neutral background with even radii, cool hairline borders, and compact pixel keycap hints.
## 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-019e4c0f-ce7e-7500-a578-aa8b915d8299/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 indigo, cyan/turquoise, and lime as a deliberately narrow cool-electric family tied to active, synced, and success states.
- Do Keep pixel fonts to labels, counters, badges, key hints, and display numerals while preserving smooth sans body readability.
- Do Make pixel elements functional: progress, sync states, selected bits, icon glyphs, and compact micro-illustrations.
- Do Favor neutral white product scenes, generous spacing, even borders, and one committed radius system.
- Don't Do not use square-grid backgrounds, default dotted textures, decorative side rails, row stripes, or card accent bars.
- Don't Do not add arcade styling, block-game references, terminal hacker tropes, excessive neon glow, or unreadable low-resolution body text.
- Don't Do not scatter rainbow colors or warm accent garnish; reserve exceptions for required semantic warning/error states.
- Don't Do not use chipped diagonal corners, uneven borders, arbitrary mixed radii, or generic SaaS dashboard layouts.

# Lumen Pixel Product System shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e4c0f-ce7e-7500-a578-aa8b915d8299`
Slug: `lumen-pixel-product-system`
## Intent
A premium consumer product UI language for calm white surfaces where pixel cues behave like precision marks: compact state bits, stepped progress chips, and pixel-influenced annotation typography set against Apple-clean layouts with cool electric indigo, cyan, turquoise, and lime highlights.
## 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:

"secondary": "#00BFD8",
"success": "#7BEF2B",
"surface": "#FFFFFF",
"text": "#111827",

"body_font": "Manrope",
"google_fonts_url": "https://fonts.googleapis.com/css2?family=Instrument+Sans:wght@500;600;700;800&family=Manrope:wght@400;500;600;700;800&family=Pixelify+Sans:wght@400;500;600;700&display=swap",

"letter_spacing": "-0.018em",
"line_height": 1.52,

}
## Visual character to preserve
- Use matte white and porcelain-neutral full-bleed backgrounds with large rounded panels, hairline borders, and no repeated grid or dotted texture.
- Render pixel identity through tiny stepped bit clusters, square indicator glyphs, and segmented progress sequences placed inside controls and data states.
- Pair smooth modern sans headings and body text with a pixel-influenced display face only for badges, counters, keyboard hints, and micro annotations.
- Apply indigo as the calm primary anchor, cyan/turquoise as active focus light, and lime as sparse success energy inside small state elements.
- Compose screens around one dominant product artifact: a consumer device sync workspace with object cards, command bands, and precise status modules.
## ShadSync visual profile
{
"family": "system",
"material": "flat",
"contour": "default",
"border": "solid",
"underlay": false,
"grain": true,

"motion": "lift",
"density": "dense",
"accents": [

]
}
## 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/lumen-pixel-product-system/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 indigo, cyan/turquoise, and lime as a deliberately narrow cool-electric family tied to active, synced, and success states.; Keep pixel fonts to labels, counters, badges, key hints, and display numerals while preserving smooth sans body readability.; Make pixel elements functional: progress, sync states, selected bits, icon glyphs, and compact micro-illustrations.; Favor neutral white product scenes, generous spacing, even borders, and one committed radius system.
- Do not: Do not use square-grid backgrounds, default dotted textures, decorative side rails, row stripes, or card accent bars.; Do not add arcade styling, block-game references, terminal hacker tropes, excessive neon glow, or unreadable low-resolution body text.; Do not scatter rainbow colors or warm accent garnish; reserve exceptions for required semantic warning/error states.; Do not use chipped diagonal corners, uneven borders, arbitrary mixed radii, or generic SaaS dashboard layouts.
## Copy-paste component example
This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
```tsx
import { Badge } from "@/components/ui/badge";
import { Button } from "@/components/ui/button";
import {
Card,
CardContent,
CardDescription,
CardFooter,
CardHeader,
CardTitle,
} from "@/components/ui/card";
import { Input } from "@/components/ui/input";
import { Tabs, TabsList, TabsTrigger } from "@/components/ui/tabs";
export function LumenPixelProductSystemShadcnKit() {
return (
