# Liquid Glass Translucency shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019daefd-9829-76f0-881c-1963821a6d3c`
Slug: `liquid-glass-translucency`

## Intent

Liquid Glass Translucency applies the material design language introduced by Apple in iOS 26 (WWDC 2025) — where interface elements behave like physically fabricated glass with real optical properties. Informed by Craig Federighi's team fabricating glass samples of varying opacities and lensing properties in Apple's industrial design studio, this language treats UI surfaces as living materials that refract, reflect, and respond to their surroundings. Balances Apple's maximal translucency with Linear's critique (removing refractive distortion that competes with content), landing on glass that enhances hierarchy rather than obscuring it.

## 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

- Frosted 24px glass panels use backdrop-filter: blur(24px) saturate(135%) over desaturated blue, lavender, and teal ambient orbs so translucency visibly refracts the scene behind it.
- Layered floating panes sit at three Z-depths: low-opacity workspace shelves, mid-opacity reading cards, and brighter foreground controls with inset white edge highlights.
- Every glass surface has a 1px rgba(255,255,255,.72) border plus inset top highlights and clipped specular glints, making edges read as physical polished glass.
- Slow animated radial-gradient orbs drift behind the product interface on 18-24 second cycles, providing meaningful motion and color for glass without distracting content.
- Navigation and active states are pill-shaped morphing glass capsules that brighten, scale slightly, and preserve legibility rather than relying on opaque color fills.

  ]
}

## 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/liquid-glass-translucency/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: Always provide a rich, colorful background behind glass — plain dark backgrounds make glass look like generic dark-mode cards; Use the inset box-shadow glass-edge highlight on every glass surface — it is the detail that sells the material illusion; Ensure text on glass passes WCAG AA contrast by using font-weight 500+ and the full-opacity text token on glass surfaces; Animate background elements slowly (15-25s cycles) — the movement should be ambient, not distracting; Layer glass panels at different opacities to create real depth — use 0.06 for large backgrounds, 0.08-0.1 for cards, 0.12-0.15 for interactive elements
- Do not: Never use backdrop-filter without a colorful background — glass over black is just a dark rectangle, defeating the entire concept; Never apply refractive distortion effects that obscure content legibility (Linear's core critique of Apple's initial implementation); Never use opaque backgrounds on containers — if something is opaque, it breaks the glass metaphor; Never skip the 1px border on glass surfaces — without it, panels have no edge definition and merge into the background; Never use heavy drop shadows — glass catches light from within (inset shadow), not from external light sources

## 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": "CSS Grid with 12-column base at 1440px. Glass panels span 4-8 columns with 24px gap. No panel touches the viewport edge — minimum 48px margin on desktop. On tablet (768px), 2-column grid with 16px gap. On mobile (375px), single column, 16px horizontal padding.",
  "breakpoints": "1440px desktop (12-col), 1024px laptop (8-col), 768px tablet (2-col), 375px mobile (1-col). Fluid typography using clamp(). Glass panel max-width: 480px on desktop for cards, full-width for hero sections.",
  "whitespace": "Generous whitespace is load-bearing — the space between glass panels IS the design. Panel internal padding: 24-32px. Inter-panel gap: 24px. Section gap: 48-64px. The dark background visible between panels creates the depth illusion."
