Boule

# Boule

## Philosophy

Boule is a hard-candy formulation console that reads a boiled sweet by its cut: every module is a cross-section of concentric jewel strata pressed into a glossy lacquer shell, set on liquorice-dark glass so the sugar is the only thing that glows. It is conceived from the same idea as its parent — an interface treated like a thin candy shell over translucent layers — but takes the opposite path: hard, dark and jewelled rather than soft, pale and milky.

### Values

- The cut is the readout: a pour is data you read by slicing the candy, layer by concentric layer.
- Three boiled-sweet jewels do the work of a whole palette, used like highlighters and always paired with a label.
- One even lacquer sheen per surface is the only shine; an even band means a sealed shell.
- Dark is functional: jewel sugars read true on near-black glass, the way they look pulled fresh from the mould.

### Anti-Values

- No pale or white ground, no pastel washes, no milky frost — Boule is jewelled and dark, not a frosted dragée.
- No gloss-band-on-rectangle panels borrowed from a soft-glass console; the cross-section dial is the organizing form.
- No rainbow refraction, neon glow, or more than three accents competing with the strata.
- No hard grey borders, accent edges, boxed pill nav, or nested cards.

### Visual Character

- A cross-section dial of concentric jewel strata — teal base, amber middle, cherry core — each ring darkened to show its fill.
- Candy slabs on a deep liquorice ground, each carrying one convex lacquer sheen at the top-left.
- Progress and composition rendered as stacked candy strata-bars in the jewel accents, never flat neutral fills.
- Heavy grotesk display (Hanken Grotesk), Space Mono readouts, rounded continuous geometry.

### Spacing

- **Base**: 8px
- **Scale**: [4,8,12,16,24,32,48,64,88,112]

### Surfaces

- **Treatment**: Candy slabs (#211B17 / recess #2B231E) on a deep liquorice #16120F ground; each surface carries one convex lacquer sheen at the top-left via radial-gradient(120% 70% at 30% -18%, rgba(255,255,255,.16), transparent 60%).
- **Card Style**: 24px rounded candy slab, low cool shadow, hairline toffee rim (inset, not a hard border), one lacquer sheen; no accent edges, no nested cards.
- **Bg Pattern**: Quiet teal and cherry radial blooms at ~8% opacity in opposite corners over the liquorice ground; the candy is the only thing that glows.

### Borders

- **Default Width**: 1px
- **Accent Width**: 2px
- **Style**: Hairline toffee rims via inset box-shadow rgba(58,48,41,1); focus rings inset 2px teal #3FC7C2; never a hard grey border.
- **Character**: Rims behave like the edge of a lacquer shell: near-invisible on neutral surfaces, a bright teal ring on focus.

### Motion

- **Duration**: 180ms
- **Easing**: cubic-bezier(.2,.8,.2,1)
- **Philosophy**: Humidity-soft: the lacquer sheen and section reveals fade only; the settled state is the default and renders with no JS; respects prefers-reduced-motion.

## Rules

### Composition

A cross-section dial of concentric jewel strata is the primary instrument; candy slabs carry supporting readouts, and strata-bars break the rhythm. Layouts are orbital (embodiment), hero-overlay (landing), and sidebar-grid (dashboard) — never an equal-card grid.

### Hierarchy

Hierarchy is made by jewel role and fill before quantity of colour: cherry is the one emphasis, amber the middle, teal the base; surfaces step liquorice -> slab -> recess; the lacquer sheen marks a sealed shell.

### Density

Airy low-to-medium density; tight 4-12px control clusters and 24-112px gaps between major groups for clean bench air.

### Signature

Cross-section dial of concentric jewel strata with fill arcs; one convex lacquer meniscus per surface; candy strata-bars for progress/composition; a three-ring boule seal mark. Surface roles: .slab, .recess (surface-2), and the dial .ring/.arc/.core.

## Layout

### Grid

Contained content caps at 1180px and centres. Embodiment uses an orbital console (dial + legend, then strata bars, readouts, controls, log, notices); dashboard uses a 248px sidebar + fluid main with KPI / dial-strata / log grids.

### Whitespace

72-120px outer section spacing, 24-48px between panels, 4-12px between labels and values.

### Density

Low-to-medium density for a confectioner's bench workflow.

### Responsive

Stacks to one column on mobile; the full-bleed hero spans 100vw and 100svh; grid children use minmax(0,1fr) + min-width:0 so nothing overflows; sidebar collapses to a top strip on mobile.

### Breakpoints

- **Mobile**: <= 640px
- **Tablet**: 641px-980px
- **Desktop**: >= 981px

## Guidance

### Do

- Make the cross-section dial the hero instrument; read layers by jewel colour and fill arc.
- Keep the ground deep liquorice; reserve cherry for the one emphasis, amber and teal for the other strata.
- Give every surface one even lacquer sheen; separate by space, the recess surface, and soft shadow.
- Render progress and composition as candy strata-bars in the jewel accents.
- Set batch ids, grams, percentages, and times in Space Mono; pair every accent with a label.

### Don't

- Do not default to a pale or white ground, or wash surfaces in pastel.
- Do not flatten the strata into one bar or one colour, or use more than three jewel accents.
- Do not add a second shine, a hard grey border, an accent edge, or a boxed nav widget.
- Do not nest cards or rely on colour alone for state.
- Do not borrow the soft-glass gloss-band-on-rectangle motif; the cross-section is the form.

### Accessibility

Maintain WCAG AA contrast: cream #F4EDE3 on liquorice #16120F and on slabs; visible teal focus rings on every control; jewel state always paired with a text label; respect prefers-reduced-motion.

## Imagery Direction

### Pairs With

glace-atelier

### Summary

Subjects sealed in the Glace Atelier candy glaze, then sliced to a cross-section: a glossy boiled-sweet form revealing concentric jewel strata (teal base, amber middle, cherry core), one clean gloss band, an aqua condensation rim, lit dramatically on a deep liquorice near-black ground so the sugar is the only thing that glows.

### Subjects

- sliced boiled-sweet and hard-candy cross-sections
- glossy domed confections on dark glass
- layered sugar-glass still-life studies
- single rounded candy forms under hot studio light

### Usage

One full-bleed candy-glaze hero per landing with dark negative space on one side for a legible overlay; feature crops use the same technique. Keep the ground liquorice-dark, the jewels saturated, and the gloss band singular. Avoid pale grounds, rainbow refraction, and neon glow.

## 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-019ef9ed-10eb-7901-bd3e-d5c1df9f83ea/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 Make the cross-section dial the hero instrument; read layers by jewel colour and fill arc.
- Do Keep the ground deep liquorice; reserve cherry for the one emphasis, amber and teal for the other strata.
- Do Give every surface one even lacquer sheen; separate by space, the recess surface, and soft shadow.
- Do Render progress and composition as candy strata-bars in the jewel accents.
- Do Set batch ids, grams, percentages, and times in Space Mono; pair every accent with a label.
- Don't Do not default to a pale or white ground, or wash surfaces in pastel.
- Don't Do not flatten the strata into one bar or one colour, or use more than three jewel accents.
- Don't Do not add a second shine, a hard grey border, an accent edge, or a boxed nav widget.
- Don't Do not nest cards or rely on colour alone for state.
- Don't Do not borrow the soft-glass gloss-band-on-rectangle motif; the cross-section is the form.

### Accessibility

Maintain WCAG AA contrast: cream #F4EDE3 on liquorice #16120F and on slabs; visible teal focus rings on every control; jewel state always paired with a text label; respect prefers-reduced-motion.
