# Voxel Product Architecture

## Philosophy

Voxel Product Architecture turns pixel art into a tactile product operating system: modular clay blocks, object-scale extrusions, and toy-bright status cubes build interfaces that feel assembled rather than drawn.

### Values

- object-like modularity
- legible low-resolution hierarchy
- warm material restraint
- stateful construction logic

### Anti-Values

- nostalgic arcade clutter
- generic neon cyber dashboards
- soft SaaS cards with pixel decorations

### Visual Character

- Use 12px and 24px square modules as visible construction units in cards, controls, charts, and navigation rails.
- Build depth with stepped box-shadow offsets at exact 4px increments instead of blur-heavy shadows or gradients.
- Pair matte clay-neutral panels with small toy-bright cuboid accents reserved for state, selection, and product landmarks.
- Render data and imagery as chunky bitmap mosaics, isometric shelves, and extruded block labels rather than smooth icons.

# Voxel Product Architecture

## Overview

Voxel Product Architecture turns pixel art into a tactile product operating system: modular clay blocks, object-scale extrusions, and toy-bright status cubes build interfaces that feel assembled rather than drawn.

### Values

- object-like modularity
- legible low-resolution hierarchy
- warm material restraint
- stateful construction logic

### Anti-Values

- nostalgic arcade clutter
- generic neon cyber dashboards
- soft SaaS cards with pixel decorations

### Visual Character

- Use 12px and 24px square modules as visible construction units in cards, controls, charts, and navigation rails.
- Build depth with stepped box-shadow offsets at exact 4px increments instead of blur-heavy shadows or gradients.
- Pair matte clay-neutral panels with small toy-bright cuboid accents reserved for state, selection, and product landmarks.
- Render data and imagery as chunky bitmap mosaics, isometric shelves, and extruded block labels rather than smooth icons.

## 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 | `#F2C14E` |
| background | `#E8DED0` |
| border | `#2B211B` |
| error | `#C94B3D` |
| info | `#4776D0` |
| muted | `#7E7063` |
| primary | `#D96B3B` |
| secondary | `#5B7CFA` |
| success | `#3F9B67` |
| surface | `#F7F0E6` |
| text | `#241D18` |
| warning | `#E39A2F` |

- **Treatment**: matte clay panels with hard ink edges and sparse 12px block inlays

### Borders

- **Accent Width**: 4px
- **Character**: dark construction-line borders with accent cube tabs at selected corners
- **Default Width**: 2px
- **Style**: solid

## Components

### Composition

Favor one dominant extruded product object surrounded by smaller control blocks; every screen should read as a miniature isometric workbench, not a flat dashboard.

### Density

Medium-high density with tight 8px label groups inside larger 32px and 64px construction bays.

### Hierarchy

Make hierarchy through block scale, extrusion depth, and toy-bright corner tabs; typography supports the architecture with compact labels and oversized geometric headings.

### Signature Patterns

- Cuboid action buttons use a 2px ink border, 8px hard offset shadow, and active transform that collapses the shadow to 4px.
- Status and progress data appear as bitmap stacks of 12px square cells with missing cells used as meaningful negative space.
- Primary panels carry an isometric shelf header: offset clay layers with colored cube tabs marking the current product zone.
- Form fields are recessed pixel wells with dark top-left inner lines and small block handles for focus and validation states.

## 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-019e66f7-61c9-7a32-98fc-7106864c1612/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.

# Voxel Product Architecture shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e66f7-61c9-7a32-98fc-7106864c1612`
Slug: `voxel-product-architecture`

## Intent

Voxel Product Architecture turns pixel art into a tactile product operating system: modular clay blocks, object-scale extrusions, and toy-bright status cubes build interfaces that feel assembled rather than drawn.

## 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": "#F2C14E",
  "background": "#E8DED0",
  "border": "#2B211B",
  "error": "#C94B3D",
  "info": "#4776D0",
  "muted": "#7E7063",
  "primary": "#D96B3B",
  "secondary": "#5B7CFA",
  "success": "#3F9B67",
  "surface": "#F7F0E6",
  "text": "#241D18",
  "warning": "#E39A2F"
}

Typography:

{
  "base_size": "16px",
  "body_font": "IBM Plex Sans",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@500;600&family=IBM+Plex+Sans:wght@400;500;600;700&family=Space+Grotesk:wght@600;700&display=swap",
  "heading_font": "Space Grotesk",
  "letter_spacing": "-0.015em",
  "line_height": 1.48,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.25
}

## Visual character to preserve

- Use 12px and 24px square modules as visible construction units in cards, controls, charts, and navigation rails.
- Build depth with stepped box-shadow offsets at exact 4px increments instead of blur-heavy shadows or gradients.
- Pair matte clay-neutral panels with small toy-bright cuboid accents reserved for state, selection, and product landmarks.
- Render data and imagery as chunky bitmap mosaics, isometric shelves, and extruded block labels rather than smooth icons.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": false,
  "stickerBadges": false,
  "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-edged block shadows instead of blur to create tactile product depth.; Reserve bright colors for state cubes, selected tabs, and meaningful product landmarks.; Make data, icons, and imagery visibly constructed from square modules.; Let one dominant product object organize each composition.
- Do not: Do not cover the screen in nostalgic game references or arcade sprites.; Do not use glassmorphism, soft neumorphism, or gradient-heavy dimensionality.; Do not mix arbitrary radii; stay on the 0, 2, 4, and 8px geometry.; Do not let semantic colors replace the cuboid structural hierarchy.

## Copy-paste component example

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