# Lumen Step Product System shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e4685-5b51-7013-99cc-23248878580d`
Slug: `lumen-step-product-system`

## Intent

Lumen Step is a premium white product-interface language where minimalist pixel-art discipline appears as crisp stepped highlights, tiny resolution-aware glyphs, and quantized component edges rather than nostalgia or game theming.

## 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": "#C7F548",
  "accent_text": "#18202A",
  "background": "#FAFAF6",
  "border": "#D8DEE8",
  "error": "#B84A5B",
  "info": "#5E83D8",
  "muted": "#66707C",
  "muted_text": "#66707C",
  "primary": "#2D4F8F",
  "primary_text": "#FFFFFF",
  "secondary": "#DCE6FF",
  "secondary_text": "#18202A",
  "success": "#4E8A67",
  "surface": "#FFFFFF",
  "surface_alt": "#F5F7FA",
  "text": "#18202A",
  "warning": "#A87622"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Afacad",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Afacad:wght@400;500;600;700&family=Fragment+Mono&family=Instrument+Sans:wght@500;600;700;800&display=swap",
  "heading_font": "Instrument Sans",
  "letter_spacing": "-0.02em",
  "line_height": 1.5,
  "mono_font": "Fragment Mono",
  "scale_ratio": 1.25
}

## Visual character to preserve

- Porcelain white page background with flat warm-white cards separated by 1px blue-grey hairlines and almost no drop shadow.
- Selected and important states use 4px stepped corner tabs built from orthogonal box-shadow blocks, never rounded side rails.
- Tiny pixel glyphs are drawn as inline 2px CSS blocks inside badges, buttons, and metadata labels for sparse rhythmic punctuation.
- Bright citron highlight is paired with cool periwinkle ink so vivid color appears in small structured planes, not confetti.
- Corners commit to a compact 10px product radius with occasional clipped 90-degree notches to create a high-resolution/low-resolution tension.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": false,
  "stickerBadges": true,
  "motion": "still",
  "density": "dense",
  "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/lumen-step-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 citron for the single most important focus or action, not every positive state.; Draw pixel influence as small CSS block glyphs, stepped tabs, or clipped corners embedded in components.; Keep white and neutral surfaces dominant so accents feel expensive and intentional.; Style every form control, focus ring, table row, and tooltip with the same stepped-corner logic.
- Do not: Do not use square-grid backgrounds, dotted textures, arcade motifs, or blocky wallpaper.; Do not add colored side rails or left-border garnish to cards, rows, buttons, or panels.; Do not spread multiple bright hues across charts or decorative confetti.; Do not use generic rounded shadow cards as the primary identity.

## Copy-paste component example

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

  "grid": "Twelve-column desktop grid with a dominant 7-column workspace, 3-column tools, and 2-column status stack; mobile collapses to one column.",
  "whitespace": "Whitespace ranges from 4px glyph pixels to 64px section gaps so proximity, not extra containers, groups information."
