# Retro Web Toy OS shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e66f7-d8c8-7cc0-a443-da5e7b845a6f`
Slug: `retro-web-toy-os`

## Intent

Retro Web Toy OS turns a browser-era desktop into a cheerful product system: grey window chrome, link-blue decisions, tiny icon color, pixel pointers, and toy-like constraint without collapsing into nostalgia parody.

## 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": "#FFB000",
  "background": "#D8DDE5",
  "border": "#657287",
  "error": "#D93232",
  "info": "#0084C7",
  "muted": "#6B7280",
  "primary": "#0645D8",
  "secondary": "#C0C7D1",
  "success": "#168A42",
  "surface": "#F2F4F7",
  "text": "#111827",
  "warning": "#F0A000"
}

Typography:

{
  "base_size": "16px",
  "body_font": "IBM Plex Sans",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@400;500;600;700&family=Pixelify+Sans:wght@500;600;700&family=Roboto+Mono:wght@400;500;700&display=swap",
  "heading_font": "Pixelify Sans",
  "letter_spacing": "-0.01em",
  "line_height": 1.45,
  "mono_font": "Roboto Mono",
  "scale_ratio": 1.2
}

## Visual character to preserve

- Every major container uses squared 0 or 2px radii, double 1px borders, and a darker bottom-right edge to mimic early browser window chrome.
- The page background is a muted desktop grey grid with tiny tiled icon marks and no soft gradients, keeping the low-resolution canvas visible.
- Navigation, buttons, tabs, and links use saturated browser blue underlines or block highlights paired with grey bevel controls.
- Status modules are arranged like draggable mini windows with title bars, traffic-light icon chips, pixel cursor arrows, and sprite badges.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": false,
  "stickerBadges": true,
  "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/retro-web-toy-os/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: Keep corners square and commit to bevel geometry everywhere.; Use link blue for true actions, selected tabs, and keyboard focus.; Make product scenes feel like a real desktop toy with files, windows, queues, and states.
- Do not: Do not add glassmorphism, blurry neon glows, or arbitrary plush radii.; Do not rely on nostalgia labels without functional interface hierarchy.; Do not use more than a few icon colors in one panel; preserve the limited desktop palette.

## Copy-paste component example

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

import { Tabs, TabsList, TabsTrigger } from "@/components/ui/tabs";

export function RetroWebToyOsShadcnKit() {
