# Braun Functional Minimalism shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019da134-4ac8-7631-b242-bde2d56cc6f2`
Slug: `braun-functional-minimalism`

## Intent

A restrained interface language derived from Dieter Rams and Braun industrial design: neutral surfaces, precise alignment, and controls that communicate function before personality. The interface should feel engineered, durable, and quietly confident rather than expressive or 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:

{
  "primary": "#2E3133",
  "secondary": "#6E7377",
  "accent": "#D96A32",
  "background": "#ECE7DE",
  "surface": "#F7F3EC",
  "text": "#17191A",
  "muted": "#8C877F",
  "border": "#B8B0A4",
  "error": "#B7442A",
  "success": "#4E6B50",
  "warning": "#B9832F",
  "info": "#5C7688"
}

Typography:

{
  "heading_font": "Archivo",
  "body_font": "Archivo",
  "mono_font": "IBM Plex Mono",
  "base_size": "16px",
  "scale_ratio": 1.2,
  "line_height": 1.5,
  "letter_spacing": "0.01em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Archivo:wght@400;500;600;700&family=IBM+Plex+Mono:wght@400;500&display=swap"
}

## Visual character to preserve

- Large fields of warm off-white and graphite are interrupted by thin keyline dividers, so sections are separated with hairline rules instead of heavy cards or colorful panels.
- Controls sit inside precise rounded-rectangle tracks with measured 1px borders, restrained shadows, and monochrome iconography that makes each element feel like a physical Braun appliance interface.
- Typography uses disciplined sans-serif stacks with uppercase micro-labels, tabular numerals, and generous line spacing, creating a neutral instruction-manual tone instead of editorial drama.
- Accent color is used sparingly as a functional signal on toggles, level meters, focus rings, and status dots, never as background fill for large surfaces or decorative illustration.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": true,
  "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/braun-functional-minimalism/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 keylines, measured spacing, and neutral surfaces to separate content before reaching for color.; Make controls self-explanatory with labels, values, and visible mechanical states.; Reserve accent color for active state, warning, or live signal feedback.
- Do not: Do not introduce ornamental illustrations, soft blobs, or expressive gradients.; Do not rely on oversized hero text when alignment and labeling can do the work.; Do not hide important actions inside visually ambiguous minimalist treatments.

## 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

{
  "grid": "A 12-column desktop grid collapses to 8 columns on tablet and a single measured column on mobile, with modules spanning whole columns rather than arbitrary card widths.",
  "breakpoints": "desktop 1440, tablet 768, mobile 375 with stacked panels and full-width controls on small screens.",
  "whitespace": "Whitespace is deliberate and even, favoring consistent gutters and module padding over dramatic empty voids; every gap should feel engineered."
