# Voxel Product Architecture shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e6995-df38-7653-886a-026755b1ef2c`
Slug: `voxel-product-architecture`

## Intent

Voxel Product Architecture turns pixel-art memory into useful product space: matte modular blocks, clay-neutral slabs, and toy-bright function cubes create interfaces that feel assembled at object scale rather than drawn on glass.

## 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": "#F4C542",
  "background": "#E8D8C5",
  "border": "#3A2A22",
  "error": "#D94B3D",
  "info": "#2C9AB7",
  "muted": "#8E7665",
  "primary": "#2D6CDF",
  "secondary": "#C96B3C",
  "success": "#37A875",
  "surface": "#F5EADB",
  "text": "#2B211B",
  "warning": "#E6A72A"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Atkinson Hyperlegible",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Atkinson+Hyperlegible:wght@400;700&family=IBM+Plex+Mono:wght@500;700&family=Space+Grotesk:wght@500;700&display=swap",
  "heading_font": "Space Grotesk",
  "letter_spacing": "-0.01em",
  "line_height": 1.48,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- Use square and eight-pixel stepped silhouettes for cards, buttons, nav rails, and chart cells so every surface reads as a snapped-together voxel block.
- Layer clay-neutral matte panels with hard offset block shadows measured in 4px increments, avoiding blur except for a tiny ambient contact shadow.
- Build hero and data areas from visible bitmap grids, extruded cube cells, and isometric stair-step dividers rather than fluid gradients or soft waves.
- Reserve toy-bright red, blue, yellow, and mint accents for semantic product modules, status cubes, focus rings, and small UI plugs on mostly warm neutral architecture.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "stickerBadges": true,
  "motion": "still",
  "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/voxel-product-architecture/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 hard block shadows and clipped stepped corners consistently across panels and controls.; Keep backgrounds warm and matte, spending bright colors only on meaningful modules or live states.; Represent data as tiles, cube stacks, inventory rows, or build-board coordinates.; Make responsive layouts re-stack like physical blocks rather than merely shrinking cards.
- Do not: Do not use neon arcade palettes, glossy gradients, or CRT scanlines as the main identity.; Do not scatter pixel icons as decoration without a grid role or product state.; Do not mix arbitrary large radii with square block geometry.; Do not let status colors replace typographic and spatial hierarchy.

## Copy-paste component example

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

## Layout notes

{
  "breakpoints": "desktop >= 1180px uses three architectural zones; tablet 720-1179px stacks command rail over board; mobile < 720px becomes a single-column block itinerary.",
  "grid": "An 8px base grid with 16px visible construction cells, a 12-column desktop shell, and nested 4-column block clusters for controls.",
  "whitespace": "Whitespace is treated as baseplate space: broad matte gutters around hero modules, tight 8px joins inside component clusters, and 24px minimum between unrelated blocks."
