# Signal Pixel White Console

## Philosophy

A clean white product interface where tiny pixel-state artifacts behave like precision signal equipment: lime is reserved for activation, focus, progress, and live telemetry, while indigo and cyan create calm structure without becoming a game skin.

### Values

- state color has product meaning
- white space as premium material
- pixel details as precision notation
- calm hierarchy before decoration

### Anti-Values

- square-grid backgrounds or default dotted texture
- arcade or cyberpunk neon overload
- generic SaaS dashboard garnish
- low-resolution type that damages readability

### Visual Character

- White and near-white panels use hairline indigo-cyan borders with a single consistent 18px geometry and no colored side rails.
- Neon lime appears only as small pixel blocks, focus rings, progress ticks, live badges, and active control fills on neutral surfaces.
- Large readable grotesk typography is paired with a pixel-influenced mono accent for counters, state labels, badges, and technical annotations.
- Components use inset pixel notches made from 4px square pseudo-elements placed inside corners rather than chipped or uneven outer borders.
- Compositions center one dominant product workspace with a deliberate offset telemetry strip instead of rows of equal dashboard cards.

# Signal Pixel White Console

## Overview

A clean white product interface where tiny pixel-state artifacts behave like precision signal equipment: lime is reserved for activation, focus, progress, and live telemetry, while indigo and cyan create calm structure without becoming a game skin.

### Values

- state color has product meaning
- white space as premium material
- pixel details as precision notation
- calm hierarchy before decoration

### Anti-Values

- square-grid backgrounds or default dotted texture
- arcade or cyberpunk neon overload
- generic SaaS dashboard garnish
- low-resolution type that damages readability

### Visual Character

- White and near-white panels use hairline indigo-cyan borders with a single consistent 18px geometry and no colored side rails.
- Neon lime appears only as small pixel blocks, focus rings, progress ticks, live badges, and active control fills on neutral surfaces.
- Large readable grotesk typography is paired with a pixel-influenced mono accent for counters, state labels, badges, and technical annotations.
- Components use inset pixel notches made from 4px square pseudo-elements placed inside corners rather than chipped or uneven outer borders.
- Compositions center one dominant product workspace with a deliberate offset telemetry strip instead of rows of equal dashboard cards.

## Colors

## Components

### Composition

Use a single dominant application workspace on a white field, with one offset telemetry strip or inspector panel to break the grid and create a memorable spatial relationship.

### Density

Balanced premium density: controls are compact but surrounded by generous 32px to 64px group spacing.

### Hierarchy

Headlines use compact grotesk weight and body text stays readable; Kode Mono is reserved for pixel labels, counters, coordinates, and short state annotations.

### Signature Patterns

- Pixel-state chips combine a 4px lime square, mono uppercase label, and soft white capsule to mark live, active, or complete states.
- Focusable controls use a two-layer cyan then lime outline with a short stepped box-shadow instead of generic glow or browser default rings.
- Progress and loading appear as segmented lime pixel ticks embedded inside white tracks, never as rainbow bars or gradients.
- Stateful cards include tiny inset corner pixels drawn with pseudo-elements while retaining smooth outer radii and even borders.
- One offset telemetry strip overlaps the main workspace by 24px to break the grid and show live data without becoming a sidebar stripe.

## 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-4907-7bd3-91b3-a33e1b3fbc32/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 lime only for focus, activation, progress, live signal, and successful completion.
- Do Keep body copy in Albert Sans and reserve Kode Mono for short accents or numeric data.
- Do Let white/neutral surfaces dominate and use indigo/cyan for structural hierarchy.
- Don't Do not use square grid backgrounds, repeated dotted texture, or retro arcade styling.
- Don't Do not add colored side rails, card stripes, chipped corners, or uneven borders.
- Don't Do not expand into rainbow palettes or use neon as garnish without a state meaning.

# Signal Pixel White Console shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e4c0f-4907-7bd3-91b3-a33e1b3fbc32`
Slug: `signal-pixel-white-console`

## Intent

A clean white product interface where tiny pixel-state artifacts behave like precision signal equipment: lime is reserved for activation, focus, progress, and live telemetry, while indigo and cyan create calm structure without becoming a game skin.

## 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": "#B7FF1A",
  "background": "#F8FAFC",
  "border": "#D6E3EF",
  "error": "#D92D4B",
  "info": "#17B7E8",
  "muted": "#64748B",
  "primary": "#241B8F",
  "secondary": "#0E9CC8",
  "success": "#5EEA3D",
  "surface": "#FFFFFF",
  "text": "#111827",
  "warning": "#D6A600"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Albert Sans",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Albert+Sans:wght@400;500;600;700&family=Familjen+Grotesk:wght@500;600;700&family=Kode+Mono:wght@400;500;600&display=swap",
  "heading_font": "Familjen Grotesk",
  "letter_spacing": "-0.02em",
  "line_height": 1.5,
  "mono_font": "Kode Mono",
  "scale_ratio": 1.24
}

## Visual character to preserve

- White and near-white panels use hairline indigo-cyan borders with a single consistent 18px geometry and no colored side rails.
- Neon lime appears only as small pixel blocks, focus rings, progress ticks, live badges, and active control fills on neutral surfaces.
- Large readable grotesk typography is paired with a pixel-influenced mono accent for counters, state labels, badges, and technical annotations.
- Components use inset pixel notches made from 4px square pseudo-elements placed inside corners rather than chipped or uneven outer borders.
- Compositions center one dominant product workspace with a deliberate offset telemetry strip instead of rows of equal dashboard cards.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "solid",

    "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/signal-pixel-white-console/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 lime only for focus, activation, progress, live signal, and successful completion.; Keep body copy in Albert Sans and reserve Kode Mono for short accents or numeric data.; Let white/neutral surfaces dominate and use indigo/cyan for structural hierarchy.
- Do not: Do not use square grid backgrounds, repeated dotted texture, or retro arcade styling.; Do not add colored side rails, card stripes, chipped corners, or uneven borders.; Do not expand into rainbow palettes or use neon as garnish without a state meaning.
