# Arcade Snack Maximalism shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e66f7-82db-7281-823f-971c932a5819`
Slug: `arcade-snack-maximalism`

## Intent

Arcade Snack Maximalism turns a product interface into a loud cabinet-side snack run: low-resolution structure, soda-machine color, and tile-map choreography organize real operational content without becoming a nostalgia costume.

## 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": "#FFE04B",
  "background": "#FFF2C7",
  "border": "#16120F",
  "error": "#D6182B",
  "info": "#19B8FF",
  "muted": "#6E513A",
  "primary": "#E9252A",
  "secondary": "#1664FF",
  "success": "#24C25A",
  "surface": "#FFF8DF",
  "text": "#16120F",
  "warning": "#FFB000"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Atkinson Hyperlegible",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Atkinson+Hyperlegible:wght@400;700&family=Bungee&family=IBM+Plex+Mono:wght@500;700&display=swap",
  "heading_font": "Bungee",
  "letter_spacing": "-0.01em",
  "line_height": 1.45,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.25
}

## Visual character to preserve

- Use an 8px bitmap grid with hard 0px and 4px radii, stepped card corners, and orthogonal gaps that align every panel to tile units.
- Build surfaces from flat soda red, electric blue, lemon yellow, candy green, cream, and near-black with double pixel borders and offset shadow blocks.
- Set headings in chunky display type with mono UI labels, uppercase microcopy, tight letter spacing, and badge-like sprite captions.
- Layer checkerboard, dither-dot, scanline, and tiny tile-map motifs as bounded UI materials rather than full-page texture noise.
- Compose dashboards like an arcade cabinet: top marquee, left cartridge rail, center playable board, right score/ticket column, and bottom status inventory.

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "solid",
  "underlay": true,
  "grain": true,
  "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/arcade-snack-maximalism/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 candy color zones to indicate product areas, not random decoration.; Keep every edge square, stepped, or deliberately 4px; avoid mixed soft radii.; Make data, controls, navigation, and empty states share the same pixel tile grammar.; Preserve accessible contrast by pairing bright fills with near-black text and thick borders.
- Do not: Do not rely on generic arcade clipart without structural grid behavior.; Do not use blur, glassmorphism, pastel gradients, or soft floating shadows.; Do not let all semantic states become equally loud; reserve red and yellow for true urgency.; Do not make the mobile view a shrunken desktop cabinet; stack zones as playable cartridges.

## Copy-paste component example

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