# Federal Grid Minimalism shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019ddbdb-f900-7093-b1a6-68c5885e0f71`
Slug: `federal-grid-minimalism`

## Intent

Federal Grid Minimalism is a Swiss-inspired interface language for public-service and enterprise products where content, task completion, and legibility take priority over decoration. It uses strict grid alignment, black-white-gray restraint, measured spacing, and a single disciplined blue accent to create calm authority without visual noise.

## 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": "#000000",
  "secondary": "#2F3337",
  "accent": "#0057D9",
  "background": "#FFFFFF",
  "surface": "#FFFFFF",
  "text": "#111111",
  "muted": "#6B7280",
  "border": "#D1D5DB",
  "error": "#B00020",
  "success": "#0B6B3A",
  "warning": "#8A5A00",
  "info": "#0057D9",
  "rule_dark": "#111111",
  "rule_light": "#E5E7EB",
  "panel_tint": "#F7F8FA",
  "focus_ring": "#0057D9"
}

Typography:

{
  "heading_font": "Suisse Intl",
  "body_font": "Inter",
  "mono_font": "JetBrains Mono",
  "base_size": "16px",
  "scale_ratio": 1.2,
  "line_height": 1.55,
  "letter_spacing": "-0.02em",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700;800&family=JetBrains+Mono:wght@500;700&display=swap"
}

## Visual character to preserve

- Use a 12-column grid with visible alignment discipline, left-anchored content blocks, and no centered hero ornamentation.
- Render interface sections with thin one-pixel rules, square corners, and white surfaces instead of shadows or floating cards.
- Establish hierarchy through type scale, uppercase micro-labels, rule weight, and spacing rather than color variety.
- Reserve a single cobalt-blue accent for primary actions, focus states, active navigation, and critical progress markers.
- Apply an 8px spacing token system with strong vertical rhythm so related content groups read as measured civic forms.

## ShadSync visual profile

{
  "family": "brutalist",
  "material": "ink",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "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/federal-grid-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: Write headings as clear tasks or nouns, not campaign slogans.; Use rules and spacing before adding background fills.; Keep accent blue for active, focused, or primary actions only.; Align labels, values, and controls to a shared grid.
- Do not: Do not use rounded cards, drop shadows, gradients, or decorative illustrations.; Do not introduce extra brand colors for secondary emphasis.; Do not center dense operational content when a left-aligned flow is clearer.; Do not hide essential labels behind icons or vague microcopy.

## Copy-paste component example

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