Vitrine

# Vitrine

## Philosophy

Vitrine is a liquid-glass material language for collections software, set on a deep cool ground. Translucent frosted panes blur and saturate the field behind them, luminous hairlines catch light along every edge, and a clipped specular streak reads as polished crystal. It keeps the source's thesis that glass only reads as glass over a rich, colourful ground — so depth itself, not decoration, carries the hierarchy. Faithful refinement of Liquid Glass Translucency, brought to standard.

### Values

- Material honesty — surfaces reveal what lies beneath, building hierarchy through depth not decoration
- Layered depth — three Z-depths of glass create a real parallax sense of space
- Contextual legibility — text holds full opacity and weight 500+ so contrast passes AA on any pane
- Refraction needs a ground — glass sits over a deep cool field with drifting orbs, never flat black
- Restrained spectacle — effects serve navigation clarity, never compete with content

### Anti-Values

- Opaque containers that hide the spatial relationships between layers
- Glass over a flat or pure-black background that reads as a generic dark card
- One-sided accent edges on rounded panes
- Decorative blur that reduces readability without adding spatial information
- Boxed-in pill navigation and nested cards

- **Full**: 9999px

### Shadows

- **Sm**: 0 2px 10px rgba(4,14,20,0.35)
- **Md**: 0 14px 40px rgba(4,14,20,0.45)
- **Lg**: 0 28px 80px rgba(4,14,20,0.55)

### Spacing

- **Base**: 8px
- **Scale**: [4,8,12,16,24,32,48,64,96]

### Surfaces

- **Treatment**: Layered frosted glass: translucent fills over a deep teal-navy ground with drifting cyan/amethyst/sea-glass orbs, backdrop-filter blur(22px) saturate(140%).
- **Card Style**: Floating 24px panes with a 1px luminous hairline, inset top edge highlight, and a clipped specular streak; no opaque fills.
- **Bg Pattern**: Oversized blurred cyan, amethyst, and sea-glass orbs drift behind the interface on 18-26s cycles; atmospheric, soft under reduced motion.
- **Glass Background**: rgba(173,226,232,0.10)
- **Glass Border**: rgba(220,248,250,0.55)

### Borders

- **Default Width**: 1px
- **Accent Width**: 1px
- **Style**: solid
- **Character**: Single luminous white-cyan hairline plus an inset top highlight; accent indicators are separate pseudo-elements, never a one-sided border on a rounded pane.

### Motion

- **Duration**: 320ms
- **Easing**: cubic-bezier(0.2, 0, 0, 1)
- **Philosophy**: Calm material morphing: controls lift and brighten as if catching light; ambient orbs drift on 18-26s cycles. Settled state is the default and renders with no JS.

## Rules

### Composition

Scene-first layered depth for a fictional collections studio: one oversized editorial accession pane breaks the grid, a narrow glass navigation rail floats independently, and dense loan/conservation modules sit at lower opacity. The deep cool ground stays visible in the gaps, making depth part of the information hierarchy.

### Hierarchy

Hierarchy comes from glass opacity, pane size, typographic voice, and Z-depth. Fraunces display headings at -0.035em tracking / 1.12 line-height; Source Sans 3 body at -0.01em / 1.55. Foreground actions are brighter glass pills; secondary data sits on quieter translucent shelves.

### Density

Mixed density: the hero accession pane is spacious with 48-96px breathing room, while loan tables and task lists are compact at 8-12px gaps. The contrast prevents uniform dashboard spacing.

### Signature

Every container shares the .glass treatment (translucent fill + blur(22px) saturate(140%) + 1px luminous hairline + inset top highlight + clipped specular streak); state changes morph via backdrop-filter and scale; an ambient orb field refracts behind the content.

## Layout

### Grid

CSS Grid, 12-column base at 1200px; one oversized editorial pane plus inset dense modules, never equal cards. Panels keep a 48px+ margin from the viewport edge on desktop. Tracks use minmax(0,1fr) with min-width:0 children so panes never overflow.

### Whitespace

Generous and load-bearing — the cool ground visible between panes IS the depth. Panel padding 24-48px; inter-panel gap 24px; section gap 64-96px; always pad above titles.

### Density

Spacious hero panes contrast with compact data shelves.

### Responsive

Renders from ~390px mobile to 2560px+ ultra-wide; single column on mobile with nav and non-essential table columns hidden; contained content capped and centred on ultra-wide while only the hero spans 100vw.

### Breakpoints

- **Mobile**: 390px
- **Tablet**: 760px
- **Laptop**: 1000px
- **Desktop**: 1200px

## Guidance

### Do

- Set glass over the rich deep cool ground so translucency has a real field to refract.
- Use the inset edge glint and clipped specular streak on every glass surface.
- Keep text at full opacity and weight 500+ on glass so contrast passes AA.
- Build hierarchy from pane size, opacity, and Z-depth, not from coloured fills.
- Animate the ambient orb field slowly; it is colour for the glass, not a distraction.

### Don't

- Put glass over a flat or pure-black background.
- Use opaque container fills that break the material metaphor.
- Add a one-sided accent border to a rounded pane.
- Box the nav into a floating pill or nest cards inside cards.
- Let blur or refraction reduce content legibility.

### Accessibility

Body text 17px+, table rows 14.5px+; foreground text at full opacity and weight 500+ over glass meets WCAG AA on the dark ground. Motion respects prefers-reduced-motion; the settled state renders with no JavaScript. Form controls are explicitly styled with visible focus (lens-cyan border + brightened fill).

## Imagery Direction

### Pairs With

aerogel

### Summary

Subjects rendered as if fabricated from stacked sheets of semi-transparent frosted glass and aerogel, refracting the layers behind them, with crisp specular edge glints and caustic light ripples over a cool desaturated ground. The landing hero is a layered glass display vitrine.

### Subjects

- glass display vitrine
- layered glass shelves and specimen panes
- translucent vessels and bowls
- caustic light fields

### Usage

Use the Aerogel technique for hero and feature imagery; keep it cool, clean, and luminous over the deep teal-navy ground. Avoid glossy plastic icons, warm muddy tones, or any in-image text.

## shadcn/ui Usage

When the target app uses shadcn/ui, copy DESIGN.md with shadcn instead of the plain DESIGN.md. It contains the same Katagami design-language source plus the shadcn/ui primitives, imports, theme variables, component recipes, and preview-shot guidance.

DESIGN.md with shadcn: `/language/en-019ef914-505a-7972-b4f1-23e6f1b9d67a/DESIGN.with-shadcn.md`.

The shadcn page also exposes optional machine-readable files for automation, but the human-facing handoff is DESIGN.md with shadcn.

Install recommended primitives with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

Use these primitives in shadcn apps:
- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Implementation rule for agents: import shadcn primitives from `@/components/ui/*`, apply the generated CSS variables first, then compose the language-specific recipes from the companion MD. Katagami remains the source of truth; shadcn names are the implementation surface.

## Do's and Don'ts

- Do Set glass over the rich deep cool ground so translucency has a real field to refract.
- Do Use the inset edge glint and clipped specular streak on every glass surface.
- Do Keep text at full opacity and weight 500+ on glass so contrast passes AA.
- Do Build hierarchy from pane size, opacity, and Z-depth, not from coloured fills.
- Do Animate the ambient orb field slowly; it is colour for the glass, not a distraction.
- Don't Put glass over a flat or pure-black background.
- Don't Use opaque container fills that break the material metaphor.
- Don't Add a one-sided accent border to a rounded pane.
- Don't Box the nav into a floating pill or nest cards inside cards.
- Don't Let blur or refraction reduce content legibility.

### Accessibility

Body text 17px+, table rows 14.5px+; foreground text at full opacity and weight 500+ over glass meets WCAG AA on the dark ground. Motion respects prefers-reduced-motion; the settled state renders with no JavaScript. Form controls are explicitly styled with visible focus (lens-cyan border + brightened fill).
