rules
Use a product-detail workspace rather than a dashboard: a roomy hero command band, a focused editor card, and adjacent insight objects that support a single product task.
Comfortable and premium: 32-48px section gaps, 16-24px internal card padding, tables with airy row height and compact controls.
Let scale, weight, and whitespace establish priority first; cobalt may announce the single next action while saffron may identify interpreted insight or recommended attention.
layout
Desktop 1200px, tablet 768px, mobile 375px with component reflow before content truncation.
A 12-column desktop product canvas with max width 1180px; tablet collapses to two columns and mobile stacks cards in task order.
Whitespace is the main luxury signal; maintain wide page gutters, calm card interiors, and unfilled negative space around the product object.
guidance
- Use cobalt only for the primary action, focus, active selection, and direct manipulation handles.
- Use saffron only for insight, recommendation, highlight, or warning-adjacent but non-error interpretation.
- Keep backgrounds white, porcelain, or fog-gray with no dots, grids, stripes, rails, or decorative border accents.
- Build real product scenes with named controls, data states, and interaction evidence rather than a component collage.
- Do not add rainbow semantics or more vivid hues beyond cobalt, saffron, and tiny tomato errors.
- Do not use colored side rails, card stripes, button stripes, square grids, dotted notebook textures, or confetti.
- Do not make a generic SaaS analytics dashboard; the scene should feel like a focused product interface.
- Do not rely on default browser form styles or unstyled component lists.

# White Cobalt Saffron Product UI ## Philosophy A quiet Apple-like product interface language where white space and exact graphite typography carry most of the experience, cobalt appears only for commitment and selection, and warm saffron marks moments of interpreted product insight. ### Values - product-first spaciousness - semantic color restraint - calm premium precision - high-contrast readable hierarchy ### Anti-Values - rainbow accent systems - decorative rails or stripes - generic dashboard density - confetti color or neon effects ### Visual Character - Porcelain-white page field with large unpatterned margins and layered white cards separated by one-pixel fog borders rather than colored decoration. - Cobalt is reserved for primary buttons, active segmented controls, selected table rows, focus rings, and direct manipulation handles. - Warm saffron appears as compact insight chips, small metric glow fields, and annotated callouts with pale saffron tint rather than full panels. - Graphite typography uses tight negative tracking in headings, generous line height in body text, and numeric capsules aligned to a calm modular rhythm. - Component depth comes from soft vertical shadows and translucent tint overlays of cobalt or saffron, never from extra vivid hues or patterned backgrounds. ## Tokens ### Borders - **Accent Width**: 2px - **Character**: Fog-gray structural borders by default;

# White Cobalt Saffron Product UI
## Overview
A quiet Apple-like product interface language where white space and exact graphite typography carry most of the experience, cobalt appears only for commitment and selection, and warm saffron marks moments of interpreted product insight.
### Values
- product-first spaciousness
- semantic color restraint
- calm premium precision
- high-contrast readable hierarchy
### Anti-Values
- rainbow accent systems
- decorative rails or stripes
- generic dashboard density
- confetti color or neon effects
### Visual Character
- Porcelain-white page field with large unpatterned margins and layered white cards separated by one-pixel fog borders rather than colored decoration.
- Cobalt is reserved for primary buttons, active segmented controls, selected table rows, focus rings, and direct manipulation handles.
- Warm saffron appears as compact insight chips, small metric glow fields, and annotated callouts with pale saffron tint rather than full panels.
- Graphite typography uses tight negative tracking in headings, generous line height in body text, and numeric capsules aligned to a calm modular rhythm.
- Component depth comes from soft vertical shadows and translucent tint overlays of cobalt or saffron, never from extra vivid hues or patterned backgrounds.
## 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 | `#1557D6` |
| background | `#FFFFFF` |
| border | `#E4E8EF` |
| error | `#D84A36` |
| info | `#1557D6` |
| muted | `#6E7581` |
| primary | `#1557D6` |
| secondary | `#D99A12` |
| success | `#3F7A57` |
| surface | `#F8FAFC` |
| text | `#1D1D1F` |
| warning | `#D99A12` |
## Typography
- **Headline-Lg**: Inter Tight, 1.816rem, weight 700, line-height 1.1.
- **Headline-Md**: Inter Tight, 1.488rem, weight 600, line-height 1.15.
- **Body-Md**: Inter, 16px, weight 400, line-height 1.52.
- **Label-Md**: IBM Plex Mono, 0.75rem, weight 600, line-height 1.
## Layout
### Spacing Tokens

- **Lg**: `16px`
- **Xl**: `24px`
- **2xl**: `32px`
- **3xl**: `48px`
- **4xl**: `64px`
### Breakpoints
Desktop 1200px, tablet 768px, mobile 375px with component reflow before content truncation.
### Grid
A 12-column desktop product canvas with max width 1180px; tablet collapses to two columns and mobile stacks cards in task order.
### Whitespace

## Elevation & Depth
### Shadows
- **Lg**: 0 34px 90px rgba(21, 87, 214, 0.12)
- **Md**: 0 18px 45px rgba(29, 29, 31, 0.08)
- **Sm**: 0 1px 2px rgba(29, 29, 31, 0.06)
## Shapes
### Rounded
- **Full**: `9999px`
- **Lg**: `26px`
- **Md**: `16px`
- **None**: `0px`
- **Sm**: `10px`
### Surfaces
- **Bg Pattern**: None: clean white to porcelain wash only; no dots, no square grids, no notebook texture.
- **Card Style**: Large-radius white cards, one-pixel fog borders, restrained vertical shadows, and no colored rails, stripes, or grid textures.
- **Treatment**: Unpatterned white and porcelain surfaces with occasional 4-8 percent cobalt or saffron tint overlays for semantic states.
### Borders
- **Accent Width**: 2px
- **Character**: Fog-gray structural borders by default; cobalt only for focus and selection outlines, saffron only for insight chip outlines.
- **Default Width**: 1px
- **Style**: solid
## Components
### Composition
Use a product-detail workspace rather than a dashboard: a roomy hero command band, a focused editor card, and adjacent insight objects that support a single product task.
### Density
Comfortable and premium: 32-48px section gaps, 16-24px internal card padding, tables with airy row height and compact controls.
### Hierarchy
Let scale, weight, and whitespace establish priority first; cobalt may announce the single next action while saffron may identify interpreted insight or recommended attention.
### Signature Patterns
- Cobalt commitment ring: active controls use a two-pixel cobalt outline plus a pale blue halo created with box-shadow rather than colored card edges.
- Saffron insight lens: important computed facts sit in pill-shaped ivory fields with tiny amber dot markers and warm tint, never broad yellow panels.
- Porcelain stage layering: overlapping white cards float on a very subtle top-to-bottom porcelain wash with fog borders and no background texture.
- Quiet selection geometry: chosen rows or tabs gain cobalt text, a pale cobalt fill, and a small circular check handle instead of stripes or side rails.
## 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-019e4646-3954-77b0-b38d-04dd29cd98d7/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 cobalt only for the primary action, focus, active selection, and direct manipulation handles.
- Do Use saffron only for insight, recommendation, highlight, or warning-adjacent but non-error interpretation.
- Do Keep backgrounds white, porcelain, or fog-gray with no dots, grids, stripes, rails, or decorative border accents.
- Do Build real product scenes with named controls, data states, and interaction evidence rather than a component collage.
- Don't Do not add rainbow semantics or more vivid hues beyond cobalt, saffron, and tiny tomato errors.
- Don't Do not use colored side rails, card stripes, button stripes, square grids, dotted notebook textures, or confetti.
- Don't Do not make a generic SaaS analytics dashboard; the scene should feel like a focused product interface.
- Don't Do not rely on default browser form styles or unstyled component lists.

# White Cobalt Saffron Product UI shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e4646-3954-77b0-b38d-04dd29cd98d7`
Slug: `white-cobalt-saffron-product-ui`
## Intent
A quiet Apple-like product interface language where white space and exact graphite typography carry most of the experience, cobalt appears only for commitment and selection, and warm saffron marks moments of interpreted product insight.
## 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

"body_font": "Inter",
"google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@500;600&family=Inter:wght@400;500;600;700&family=Inter+Tight:wght@500;600;700&display=swap",

"letter_spacing": "-0.018em",
"line_height": 1.52,
"mono_font": "IBM Plex Mono",

}
## Visual character to preserve
- Porcelain-white page field with large unpatterned margins and layered white cards separated by one-pixel fog borders rather than colored decoration.
- Cobalt is reserved for primary buttons, active segmented controls, selected table rows, focus rings, and direct manipulation handles.
- Warm saffron appears as compact insight chips, small metric glow fields, and annotated callouts with pale saffron tint rather than full panels.
- Graphite typography uses tight negative tracking in headings, generous line height in body text, and numeric capsules aligned to a calm modular rhythm.
- Component depth comes from soft vertical shadows and translucent tint overlays of cobalt or saffron, never from extra vivid hues or patterned backgrounds.

## 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-cobalt-saffron-product-ui/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 cobalt only for the primary action, focus, active selection, and direct manipulation handles.; Use saffron only for insight, recommendation, highlight, or warning-adjacent but non-error interpretation.; Keep backgrounds white, porcelain, or fog-gray with no dots, grids, stripes, rails, or decorative border accents.; Build real product scenes with named controls, data states, and interaction evidence rather than a component collage.
- Do not: Do not add rainbow semantics or more vivid hues beyond cobalt, saffron, and tiny tomato errors.; Do not use colored side rails, card stripes, button stripes, square grids, dotted notebook textures, or confetti.; Do not make a generic SaaS analytics dashboard; the scene should feel like a focused product interface.; Do not rely on default browser form styles or unstyled component lists.
## Copy-paste component example
This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
```tsx
import { Badge } from "@/components/ui/badge";
import { Button } from "@/components/ui/button";
import {
Card,
CardContent,
CardDescription,
CardFooter,
CardHeader,
CardTitle,
} from "@/components/ui/card";
import { Input } from "@/components/ui/input";
import { Tabs, TabsList, TabsTrigger } from "@/components/ui/tabs";
export function WhiteCobaltSaffronProductUiShadcnKit() {
return (
<section className="grid gap-4 rounded-[var(--radius)] border bg-background p-4 text-foreground">

Use the Katagami registry theme, then compose these shadcn primitives
