## Philosophy

A paper-cut diorama interface language. Every surface is a cut-paper plane in a lit shadow-box, and hierarchy comes from how far that plane floats above the page — read off its cast shadow — never from a line drawn around a box. The faithful descendant of a storybook collage idea, brought to standard: the handmade warmth, narrative staging, and child-friendly legibility are kept; the thick ink outlines, dotted-grain washes, and starburst-and-ribbon clutter are dropped.

### Values

- Depth from light and layering, never from a border
- Handmade warmth on a bright, clean cream ground — never muddy
- Narrative staging — sections behave like picture-book spreads with foreground, midground and far horizon
- Child-friendly legibility: large type, high contrast, forgiving targets
- One ornament system — the diorama itself — applied where depth is the point

### Anti-Values

- Thick ink-like outlines and single accent edges on cards
- Dotted-grain washes and gradient pastel backgrounds
- Starbursts, stitched ribbons, and stamped medallions piled on as decoration
- Arbitrary in-between radii and boxed-in widget navigation
- Defaulting the ground to white

### Visual Character

- Three depth planes (far, mid, near) carry hierarchy through soft cast shadows instead of borders
- Inputs are pressed into the page with an inset shadow, reading as cut grooves rather than bordered boxes
- Scene cards carry a small stacked-paper-hills diorama; the dashboard chart is layered paper hills
- Fraunces serif scene titles with a coral colour-pop and a gold highlighter swipe on a hero word
- A warm cream paper ground with a faint paper-fibre dot texture and three cut-paper cardstock accents

## Rules

### Composition

Stage each interface as a lit shadow-box: surfaces are cut-paper planes at three depths (far, mid, near). Hierarchy comes from how far a plane floats — read off its cast shadow — never from an outline.

### Hierarchy

Reserve the near plane and coral for action; the mid plane and slate-blue for the working surface; the far plane for quiet chrome. Inputs press into the page; buttons lift off it.

### Density

Low-to-medium. Large forgiving targets, short readable blocks, generous breathing room — the legibility a picture-book interface needs.

### Signature

The depth-stack: three soft cast-shadow planes carry the whole system, mapped onto semantic roles so they recolour on palette swap. Lists and catalogues are staged as shelves of little dioramas.

## Layout

### Grid

Contained 1160px max, full-bleed hero only; cards and panels on the mid plane, the primary action on the near plane.

### Whitespace

Generous; always pad above titles; let the cream ground breathe.

### Density

Low-to-medium with large targets.

### Responsive

Single column under ~860px; rail collapses to a wrapping nav; non-essential table columns hide under 620px; hero headline shrinks with clamp() and wraps, never clips at 390px.

### Breakpoints

- **Mobile**: 390px
- **Tablet**: 860px
- **Desktop**: 1160px
- **Ultrawide**: 2560px

## Guidance

### Do

- Let depth and light carry hierarchy; reserve the near plane for action
- Keep the cream ground bright and the three cardstocks clean
- Stage lists as shelves of little dioramas
- Press inputs into the page; lift buttons off it

### Don't

- Draw a border, single accent edge, or grey rule to separate anything
- Pile on starbursts, ribbons, or grain washes — the diorama is the ornament
- Set the headline as an italic-swap serif
- Default the ground to white

### Accessibility

Body 17px+ on a high-contrast cream/bark pairing; every control explicitly styled with a visible gold focus ring; large forgiving targets; colour never the only signal — depth, label and shape carry meaning too; motion respects prefers-reduced-motion.

## Imagery Direction

### Pairs With

shadowbox-papercut-diorama

### Summary

Cut-paper diorama imagery — layered matte cardstock at distinct depths in a lit shadow-box, soft cast shadows carrying the depth, on a warm cream paper ground with coral, slate-blue and gold accents.

### Subjects

- landscapes and small towns
- rivers and bridges
- orchards and trees
- harbours and lanterns
- animals and figures

### Usage

Hero is a wide cut-paper landscape with calm paper negative space for the overlay; scene cards and empty states use simpler single-subject dioramas.

- **Ground**: #F6EEDD
- **Plane**: #FCF7EC
- **Recessed**: #F1E6CF

### Borders

- **Default**: none
- **Seam**: 1px solid #E6DAC2

## Components

### Composition

Stage each interface as a lit shadow-box: surfaces are cut-paper planes at three depths (far, mid, near). Hierarchy comes from how far a plane floats — read off its cast shadow — never from an outline.

### Hierarchy

Reserve the near plane and coral for action; the mid plane and slate-blue for the working surface; the far plane for quiet chrome. Inputs press into the page; buttons lift off it.

### Density

Low-to-medium. Large forgiving targets, short readable blocks, generous breathing room — the legibility a picture-book interface needs.

### Signature

The depth-stack: three soft cast-shadow planes carry the whole system, mapped onto semantic roles so they recolour on palette swap. Lists and catalogues are staged as shelves of little dioramas.

## 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-019efdd8-cdc8-7602-a355-f275fc13ae05/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 Let depth and light carry hierarchy; reserve the near plane for action
- Do Keep the cream ground bright and the three cardstocks clean
- Do Stage lists as shelves of little dioramas
- Do Press inputs into the page; lift buttons off it
- Don't Draw a border, single accent edge, or grey rule to separate anything
- Don't Pile on starbursts, ribbons, or grain washes — the diorama is the ornament
- Don't Set the headline as an italic-swap serif
- Don't Default the ground to white

### Accessibility

Body 17px+ on a high-contrast cream/bark pairing; every control explicitly styled with a visible gold focus ring; large forgiving targets; colour never the only signal — depth, label and shape carry meaning too; motion respects prefers-reduced-motion.
