composition

Build a specific workspace scene with a broad white canvas, narrow utility zones, and one dominant object editor instead of a generic analytics dashboard.

density

Moderately airy with 24-48px section spacing, compact controls inside tool clusters, and no crowded card mosaics.

hierarchy

Use charcoal size and weight first, then silver containment; emerald and lavender must indicate state or context only after content structure is established.

signature patterns
Emerald productivity capsules combine a pale mint fill, a darker leading dot, and a thin progress inset to mark active work without card stripes.Lavender selection halos sit behind selected rows or objects as translucent rounded slabs with soft blur rather than borders or side rails.Silver glass shelves use inset top highlights and quiet shadow to separate surfaces on a plain white background with no texture.Command controls group into floating rounded islands where only the current action receives emerald fill and secondary context receives lavender tint.
layout
breakpoints

mobile 375px stacks inspector below editor; tablet 768px uses two-column context plus editor; desktop 1200px+ uses three-zone workspace.

grid
A responsive asymmetric product workspace: 280px left document context, fluid central editor, and 320px right inspector on desktop; stacked sections on small screens.
whitespace

Outer margins remain 24-48px and internal gaps remain 12-24px, allowing the white surface to be a material rather than empty filler.

guidance
do
  • Use emerald for active creation, saved progress, focus rings, and primary productive actions.
  • Use lavender for selection, contextual inspection, secondary panels, and object relationship cues.
  • Keep normal surfaces white, silver, and charcoal with color appearing as a small number of semantic moments.
  • Create product-specific screens with real working states, inline editing, and content-bearing controls.
avoid
  • Do not add dotted, square-grid, notebook, rainbow, or confetti backgrounds.
  • Do not use colored side rails, stripes on cards or buttons, decorative borders, or swatch-catalog layouts.
  • Do not introduce additional vivid hues beyond tiny semantic warnings/errors where required.
  • Do not make a generic SaaS dashboard with KPI tiles as the primary scene.

# White Workspace Emerald Lavender

## Philosophy

A quiet white product workspace where emerald marks productive momentum and lavender marks contextual selection, using restraint, spaciousness, and glass-silver materials to make color feel earned rather than decorative.

### Values

- product-first clarity
- premium neutral restraint
- semantic color moments
- spacious focused work
- slightly unexpected calm

### Anti-Values

- rainbow dashboards and decorative swatch collages
- colored rails, stripes, grids, dots, or confetti used as visual filler
- generic SaaS template density

### Visual Character

- White-to-silver continuous canvas with large quiet gutters, no grid texture, and cards separated by soft shadow plus one-pixel silver borders.
- Emerald appears only inside active productivity controls, progress capsules, confirmed states, and live focus rings with pale tint underlays.
- Lavender appears only as selection context: chosen object halos, segment backgrounds, annotation chips, and secondary contextual panels.
- Charcoal typography uses sharp optical hierarchy with compressed labels, generous line height, and numeric status pills aligned to content not decoration.
- Rounded rectangular components use calm 18-28px radii, inset white highlights, and hover motion that lifts two pixels without colorful stripes.

### Signature Patterns

- Emerald productivity capsules combine a pale mint fill, a darker leading dot, and a thin progress inset to mark active work without card stripes.
- Lavender selection halos sit behind selected rows or objects as translucent rounded slabs with soft blur rather than borders or side rails.
- Silver glass shelves use inset top highlights and quiet shadow to separate surfaces on a plain white background with no texture.
- Command controls group into floating rounded islands where only the current action receives emerald fill and secondary context receives lavender tint.

## 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-019e4646-ff2f-7da0-9293-c7673f67044f/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 emerald for active creation, saved progress, focus rings, and primary productive actions.
- Do Use lavender for selection, contextual inspection, secondary panels, and object relationship cues.
- Do Keep normal surfaces white, silver, and charcoal with color appearing as a small number of semantic moments.
- Do Create product-specific screens with real working states, inline editing, and content-bearing controls.
- Don't Do not add dotted, square-grid, notebook, rainbow, or confetti backgrounds.
- Don't Do not use colored side rails, stripes on cards or buttons, decorative borders, or swatch-catalog layouts.
- Don't Do not introduce additional vivid hues beyond tiny semantic warnings/errors where required.
- Don't Do not make a generic SaaS dashboard with KPI tiles as the primary scene.

# White Workspace Emerald Lavender shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e4646-ff2f-7da0-9293-c7673f67044f`
Slug: `white-workspace-emerald-lavender`

## Intent

A quiet white product workspace where emerald marks productive momentum and lavender marks contextual selection, using restraint, spaciousness, and glass-silver materials to make color feel earned rather than decorative.

## 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": "#10B981",
  "background": "#FAFAF8",
  "border": "#D9DEE6",
  "error": "#B42318",
  "info": "#7C3AED",
  "muted": "#6B7280",
  "primary": "#047857",
  "secondary": "#8B5CF6",
  "success": "#047857",
  "surface": "#FFFFFF",
  "text": "#1F2933",
  "warning": "#B7791F"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Inter",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=Instrument+Sans:wght@500;600;700&family=Inter:wght@400;500;600;700&display=swap",
  "heading_font": "Instrument Sans",
  "letter_spacing": "-0.018em",
  "line_height": 1.5,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- White-to-silver continuous canvas with large quiet gutters, no grid texture, and cards separated by soft shadow plus one-pixel silver borders.
- Emerald appears only inside active productivity controls, progress capsules, confirmed states, and live focus rings with pale tint underlays.
- Lavender appears only as selection context: chosen object halos, segment backgrounds, annotation chips, and secondary contextual panels.
- Charcoal typography uses sharp optical hierarchy with compressed labels, generous line height, and numeric status pills aligned to content not decoration.
- Rounded rectangular components use calm 18-28px radii, inset white highlights, and hover motion that lifts two pixels without colorful stripes.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "pebble",
  "border": "solid",
  "underlay": true,
  "grain": true,

  "motion": "lift",
  "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/white-workspace-emerald-lavender/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 emerald for active creation, saved progress, focus rings, and primary productive actions.; Use lavender for selection, contextual inspection, secondary panels, and object relationship cues.; Keep normal surfaces white, silver, and charcoal with color appearing as a small number of semantic moments.; Create product-specific screens with real working states, inline editing, and content-bearing controls.
- Do not: Do not add dotted, square-grid, notebook, rainbow, or confetti backgrounds.; Do not use colored side rails, stripes on cards or buttons, decorative borders, or swatch-catalog layouts.; Do not introduce additional vivid hues beyond tiny semantic warnings/errors where required.; Do not make a generic SaaS dashboard with KPI tiles as the primary scene.

## 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": "mobile 375px stacks inspector below editor; tablet 768px uses two-column context plus editor; desktop 1200px+ uses three-zone workspace.",

  "whitespace": "Outer margins remain 24-48px and internal gaps remain 12-24px, allowing the white surface to be a material rather than empty filler."
