Pomelo

# Pomelo

## Philosophy

A soft-white consumer product language where premium quiet surfaces are warmed by a melon bloom at the moment that matters and clarified by an azure cue at the precise thing you point to. Color stays rare, structural, and product-first.

### Values

- spacious product focus
- fresh consumer warmth
- disciplined two-hue color theory
- translucent material depth
- calm accessible hierarchy

### Anti-Values

- rainbow decoration or confetti
- colored rails, stripes, or single accent edges
- generic SaaS dashboard density
- dotted, gridded, or notebook backgrounds
- grey structural borders

### Visual Character

- Plain soft-white body with large untextured breathing margins and no dotted, gridded, or tiled pattern.
- Cards are translucent gray-white glass panels with broad radii and soft downward shadows; depth comes from opacity, never from grey outlines.
- Melon lives in broad hero wells, active progress fills, and the day's headline moment while generous white negative space stays around it.
- Azure is reserved for selection states, focus rings, navigation tabs, and precise secondary controls so interaction reads cool and exact.
- Oversized rounded product modules with floating capsule controls and inset tint panels rather than stripes, rails, or swatch collages.

- **Google Fonts Url**: https://fonts.googleapis.com/css2?family=Fraunces:opsz,wght@9..144,500;9..144,600;9..144,700&family=IBM+Plex+Mono:wght@500;600&family=Inter:wght@400;500;600;700&display=swap

### Radii

- **None**: 0
- **Sm**: 18px
- **Md**: 30px
- **Lg**: 30px
- **Full**: 9999px

### Shadows

- **Sm**: 0 8px 22px rgba(24,34,43,.06)
- **Md**: 0 20px 55px rgba(24,34,43,.10)
- **Melon**: 0 34px 90px rgba(255,122,92,.18)
- **Azure**: 0 18px 44px rgba(46,168,255,.16)

### Spacing

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

### Surfaces

- **Bg Pattern**: plain soft white only; no dots, grid, or notebook texture
- **Card Style**: large rounded translucent white glass with backdrop blur and soft shadow; no grey hairline outline
- **Treatment**: soft white planes, translucent gray-white panels, sparse melon or azure tint washes via radial blooms

### Borders

- **Style**: none as structure; depth from opacity and shadow
- **Default Width**: 0
- **Accent Width**: 2px
- **Character**: no decorative or structural borders; the only 2px outline is an azure focus ring or selected-control ring; a rare warm 1px inset separates inset tiles, never as a stripe or edge accent

### Motion

- **Duration**: 200ms
- **Easing**: cubic-bezier(0.2, 0.8, 0.2, 1)
- **Philosophy**: quiet consumer polish: controls lift 2px, tints brighten subtly, progress expands without bounce; settled state is default and renders with no JS

## Rules

### Composition

Center a product-first scene on a wide soft-white canvas with a breathing inline navigation, a large melon hero well, and supporting glass cards that orbit the main task rather than filling every column.

### Hierarchy

Warm Fraunces display headings, compact mono metadata, clear Inter body; the largest melon object introduces the moment while azure marks the current interactive path.

### Density

Relaxed consumer density with 24-32px card padding, wide gaps, and short readable clusters instead of dense enterprise tables.

### Signature

- Melon wells: radial melon blooms inside rounded rectangles make color structural and content-bearing without becoming a rainbow.
- Azure selection capsules sit inside neutral trays with a soft halo and 2px ring for interaction clarity.
- Translucent gray-white glass cards build depth from opacity, blur, and soft shadow instead of extra hues or borders.
- Progress and onboarding are melon fills with a small azure checkpoint, keeping both hues tied to product meaning.

## Layout

### Grid

Twelve-column desktop shell collapsing to six columns on tablet and one column on mobile; cards span by task importance rather than equal dashboard tiles.

### Whitespace

32-64px outer margins on large screens; at least 16-24px internal gaps so each color moment has quiet white around it.

### Density

relaxed

### Responsive

Renders well from ~390px mobile to 2560px+ ultra-wide; single column on mobile with non-essential nav hidden; only the full-bleed hero spans 100vw on ultra-wide.

### Breakpoints

- **Mobile**: 390px
- **Tablet**: 768px
- **Desktop**: 1200px

## Guidance

### Do

- Use melon for hero panels, warmth, progress, and the day's key moment.
- Use azure for active navigation, focus, selection, and precise secondary actions.
- Keep backgrounds plain soft white with translucent glass card depth.
- Let product copy and controls decide where color lands.

### Don't

- Add dotted, grid, notebook, stripe, or confetti backgrounds.
- Introduce a third bright hue beyond melon and azure except muted semantic states.
- Use colored side rails, card stripes, button stripes, or single accent edges.
- Present a generic analytics dashboard or a swatch collage.

### Accessibility

High-contrast #18222B text on soft white and white; explicit azure focus rings on every interactive control; all form controls fully styled with no browser defaults; color is never the only signal, progress and selection carry text and shape too.

## Imagery Direction

### Pairs With

opaline-soft-diffusion

### Summary

Forms emerging from a luminous milky-white field with no hard outlines, a warm melon glow blooming from one side and a single thin azure rim-light tracing the opposite contour. Calm, premium, airy.

### Subjects

- ripe pomelo or melon segments with translucent coral flesh
- calm consumer product still lifes
- soft-focus everyday domestic objects
- fresh fruit halves backlit in a milky field

### Usage

Landing hero is a full-viewport background-image swapped via --hero-image; keep negative space for a legible overlay; never an inline <img>.

- Azure selection capsules sit inside neutral trays with a soft halo and 2px ring for interaction clarity.
- Translucent gray-white glass cards build depth from opacity, blur, and soft shadow instead of extra hues or borders.
- Progress and onboarding are melon fills with a small azure checkpoint, keeping both hues tied to product meaning.

## 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-019efabb-88ac-7820-8f23-d5f16deb326b/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 Use melon for hero panels, warmth, progress, and the day's key moment.
- Do Use azure for active navigation, focus, selection, and precise secondary actions.
- Do Keep backgrounds plain soft white with translucent glass card depth.
- Do Let product copy and controls decide where color lands.
- Don't Add dotted, grid, notebook, stripe, or confetti backgrounds.
- Don't Introduce a third bright hue beyond melon and azure except muted semantic states.
- Don't Use colored side rails, card stripes, button stripes, or single accent edges.
- Don't Present a generic analytics dashboard or a swatch collage.

### Accessibility

High-contrast #18222B text on soft white and white; explicit azure focus rings on every interactive control; all form controls fully styled with no browser defaults; color is never the only signal, progress and selection carry text and shape too.
