Andon

# Andon

## Philosophy

Andon keeps the soul of Ma Wabi-Sabi Spatial Minimalism — Japanese ma (the meaningful interval), wabi-sabi imperfection, quiet affordance, and MUJI no-brand restraint — and reconceives its expression around one physical truth the parent only named in passing: light as hierarchy. A single warm lamp falls across the interface; the surfaces it reaches sit forward, the rest recede into warm shadow, and the one active element catches a thin amber seam. Emptiness is no longer a labelled blank bay but the unlit interval between pools of light. There are no borders; light and shadow do the structural work. An andon — the paper-and-cedar lantern — names the language and sets its behaviour: paper glows, wood frames, shadow holds the room, and one warm amber is the only saturated colour.

### Values

- {"name":"Light as hierarchy","explanation":"Priority is luminance — the most important surface is the one the lamp has reached; the rest waits in warm shadow."}
- {"name":"Active emptiness","explanation":"The dark interval between lit elements is structure; ma survives as the shadow gutter the light does not fill."}
- {"name":"Material restraint","explanation":"Surfaces read as lime plaster, washi, unglazed clay, and cedar through soft directional shadow and faint grain, never illustration."}
- {"name":"Quiet affordance","explanation":"A control is legible because the light models it — a raised plane, a recessed well — not because it is boxed or coloured."}
- {"name":"Weathered precision","explanation":"The grid is measured and rigorous; imperfection lives in the grain and the warmth of the light."}
- {"name":"No-brand neutrality","explanation":"The interface recedes behind the work — one warm accent, quiet type, sparse labels."}

### Anti-Values

- {"name":"Ornamental Japanism","explanation":"No cherry blossoms, faux calligraphy, red sun discs, or motif wallpaper; the aesthetic is carried by light, interval, and material."}
- {"name":"Luxury-spa softness","explanation":"No beige-on-beige wash, no pillowy oversized controls; the warmth is lamplight on matte material."}
- {"name":"Tech-showroom gloss","explanation":"No glassmorphism, neon, gradient buttons, or SaaS-hero effects; the glow is a wick, not a screen."}
- {"name":"Over-compression","explanation":"The screen is never packed to prove efficiency; the shadow between objects is part of the content."}

### Visual Character

- A warm directional lamplight falls across every screen from one side; lit surfaces sit forward, unlit surfaces recede.
- Lit paper planes carry a soft warm top gradient and a matching soft shadow, with no borders.
- The active element catches a single 2px luminous amber seam on its lit edge; nothing else gets an edge.
- The ma interval is an unlit shadow gutter — a column or band the light does not reach — separating regions without a rule.
- Warm amber is the only saturated colour, used like the glow of a wick — on the seam, on selection, on one call to action.

### Surfaces

- **Treatment**: paper-plaster under lamplight
- **Card Style**: Lit paper planes modelled by a soft warm directional light and shadow; elevation is depth into the light; no borders.
- **Bg Pattern**: warm directional light-fall gradient with a faint material grain

### Borders

- **Default Width**: 0px
- **Accent Width**: 2px
- **Style**: luminous-seam
- **Character**: No borders. Structure is read from light and soft shadow; the only edge is a single 2px warm amber seam that marks the active/lit element.

### Motion

- **Duration**: 260ms
- **Easing**: cubic-bezier(0.22,0.61,0.18,1)
- **Philosophy**: A lamp brightening — elements warm into presence and recede into shadow; deliberate settle, no bounce, no celebration.

## Rules

### Composition

Model a quiet asymmetrical grid with one unlit shadow gutter as the ma interval; place primary work in the pool of light slightly off-centre; separate major regions with 48-96px of interval. Hierarchy is luminance before type or colour.

### Hierarchy

Priority is how much light a surface catches: lit paper planes sit forward with a soft warm shadow; the single active element carries a 2px amber seam. Display type is Shippori Mincho; micro labels are IBM Plex Mono; amber appears only on the seam, selection, and one call to action.

### Density

Medium-low with deliberate pauses; lists compact but never crowded; forms full-height; the screen feels edited, the shadow between objects part of the content.

### Signature Patterns

- Lampfall pool: a soft warm luminance gradient plus a matching drop shadow models every raised plane; elevation is depth into the light.
- The seam: a single 2px luminous amber line marks the one active/lit element and nothing else.
- Shadow gutter: the ma interval rendered as an unlit column or band — structure by absence of light.
- Lantern-body primary: the primary button is a dark warm cedar-ink panel with a bright amber top seam and cream label.
- Recessed well: inputs are soft inset shadow wells with no border; on focus the well brightens and the amber seam appears at its lit edge.

## Layout

### Density

Medium-low; every cluster gets enough shadow to read as a deliberate pause.

### Grid

12-column field, max width ~1360px; one column is left as an unlit shadow gutter (ma); content offset into the remaining columns.

### Whitespace

Active structure: 48px minimum between regions, 64px around decision areas, 96px where the reader should slow.

### Breakpoints

- **Desktop**: 1200px and above: 12 columns with the shadow gutter
- **Tablet**: 768-1199px: 8 columns, gutter becomes a top interval
- **Mobile**: 0-767px: single column, intervals reduce to 32px but stay visible

### Responsive

Collapse side rails beneath the main panel on tablet; stack panels on mobile; keep controls 44px; let tables become card rows rather than overflow.

## Guidance

### Do

- Model hierarchy with light and shadow first; reach for the amber seam only to mark the one active element.
- Keep one warm directional light across a whole screen so the modelling is coherent.
- Let the ma interval be a genuine unlit gutter; leave it empty.
- Use warm cream labels on the dark lantern-body primary button for high contrast.
- Keep body text at 17px and letter-spacing at -0.02em on display type.
- Reserve #FFFFFF for the brightest lit surfaces and warm off-white for paper planes.

### Don't

- Do not draw boxes or grey borders; the seam and the shadow do the work.
- Do not give a card a decorative accent edge — the seam only marks the active element.
- Do not use gradients as decoration, glassmorphism, neon, or gloss.
- Do not decorate with literal Japanese motifs.
- Do not centre every section or pack the screen.
- Do not use random radii such as 8px, 12px, or 20px.

### Usage Context

Editorial desks and archives, calm operations dashboards, material libraries and catalogues, focused planning and reading tools — anywhere reduction, placing, and careful reading matter.

### Accessibility

Maintain WCAG AA contrast (cream on warm shadow, ink on lit paper); focus states raise a visible amber seam plus ring; never encode status by colour alone (status dots plus labels); keep touch targets at least 44px; keep grain behind content at low opacity.

## Imagery Direction

### Summary

Umbra tenebrist chiaroscuro: one warm low light rakes matte imperfect material (lime plaster, washi, unglazed clay, weathered cedar) out of deep warm shadow, with a single luminous amber seam. Contemplative, wabi-sabi, film-photographic scenes of lanterns, alcoves, and quiet interiors.

## 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-019f8af8-d1d6-7501-8b46-e22c51f016bd/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.
