# Limelight shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019efda2-dca8-7a32-839a-2c9a95ed64a3`
Slug: `limelight`

## Intent

Limelight treats the interface as a charged reveal. It stages an app the way a relay race stages its runners: every focal surface sits in a key-light charge frame, progress builds as a spark meter, and the most important content is lifted into view the moment it is ready. It keeps the cinematic drama of an anime spectacle screen and drops the gacha kitsch, metallic double-frames, and glassy violet wash.

## 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`.

}

## Visual character to preserve

- Charge frames: a single key light wraps one corner of a focal surface and glows in the state accent
- Spark meters: segmented charge bars that throw a gold spark at the fill edge
- Lifted reveal: a cel-anime portrait breaks out past its frame under a key-light rim
- Intensity-coded chips, avatar key-rims and meters that recolour cyan, magenta, or gold
- A deep near-black cinema-stage ground washed by a faint cyan key-glow

## ShadSync visual profile

{
  "family": "system",
  "material": "flat",
  "contour": "default",
  "border": "solid",
  "underlay": false,
  "grain": false,
  "stickerBadges": false,
  "motion": "lift",
  "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/limelight/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 cyan, magenta and gold as highlighters to encode charging, priority and complete; Wrap a focal surface's corner in a key-light bracket; never use a lonely single edge or a grey box; Stage progress as a spark meter with a gold spark at the fill edge; Let a cel-anime portrait break out of its frame for the reveal; Keep the ground a deep cinema-stage near-black so accents glow
- Do not: Do not use metallic double-frames, jewel corners, or glassy violet surfaces; Do not box the nav into a pill bar or float chrome as a widget; Do not open the hero with an eyebrow tag, a button pair, or a three-stat row; Do not swap a regular serif for an italic serif in the headline; use a colour-pop mark; Do not flatten panels into plain grey rectangles or remove the key-light entirely

## Copy-paste component example

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