Confetti

# Confetti

## Philosophy

A high-energy interface language that translates Memphis postmodern graphic design into digital product surfaces through flat die-cut shapes, loud contrast and deliberately anti-neutral composition. Every shape is cut from a confetti field, keylined once in black, and slapped down on its own hard offset shadow so it reads like a printed sticker.

### Values

- Playfulness as structure rather than decoration
- Graphic contrast that keeps hierarchy instantly legible
- Layered shapes and pattern fields that energise routine screens
- Intentional asymmetry balanced by strict alignment zones

### Anti-Values

- Corporate neutrality and invisible chrome
- Soft luxury minimalism or restrained monochrome
- Photoreal depth or skeuomorphic material imitation

### Visual Character

- Flat die-cut shapes sit behind and around content using offset circles, zig-zag dividers, dotted fields and angled bars in electric accents, each with a single crisp black keyline.
- Cards and panels rest on pale mint, white or blush paper, interrupted by a die-cut companion attached at one corner as one page-wide system.
- Typography pairs an oversized Bungee display with a clean Archivo body and uppercase IBM Plex Mono micro-labels, using strong scale jumps to feel like poster graphics.
- Buttons, tabs and metrics are printed capsules with a keyline, a hard offset shadow and a centred one-line label so every interactive element reads like a printed graphic object.

## Rules

### Composition

Compose screens as poster-like spreads with one dominant hero column, supporting stacked utility panels, and die-cut geometric ornaments occupying gutters and negative space.

### Hierarchy

Use oversized Bungee display headlines, loud colour-blocked data callouts, and compact uppercase mono labels so scanning stays instant even amid playful density.

### Density

Medium-high density with tightly grouped controls inside boldly separated modules; decoration may be abundant, but task-critical content stays boxed into quiet mint, white or blush islands.

### Signature Patterns

- Every major card uses one black keyline plus a hard offset shadow, creating a printed cutout that separates layers without blur.
- Section headers and chips carry a die-cut geometric companion (circle, bar, triangle or squiggle) recolouring through teal, pink and yellow as one system.
- Backgrounds use faint dot and dash motifs behind quiet surfaces, giving flat fields the texture of laminated postmodern stationery.
- Primary actions and status pills are teal, pink, yellow or ink capsules with uppercase labels, keeping a toy-like but highly visible control system.

## Layout

### Grid

A 12-column desktop grid collapsing to a considered tablet band and a single mobile column, with oversized outer padding so decorative shapes can live in the margins.

### Breakpoints

Wide 1920+, desktop 1440, tablet 768-1024, mobile 390 with stacked panels and full-width actions.

### Whitespace

Compact spacing inside modules, larger gaps between them, so the graphic collage stays readable and task content stays on quiet paper.

## Guidance

### Do

- Anchor every decorative gesture to a content container so the screen feels composed.
- Use the keyline and loud accent fills to clarify interaction priority before relying on motion.
- Mix mint, white and blush surfaces while keeping body text on quiet paper.

### Don't

- Nest cards or trap navigation in a floating pill bar.
- Let dot or stripe patterns cross body text.
- Smooth out all asymmetry; a slight compositional clash is part of the identity.

## 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-019f8aff-7550-7ee3-8429-d90ca52e7b5c/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 Anchor every decorative gesture to a content container so the screen feels composed.
- Do Use the keyline and loud accent fills to clarify interaction priority before relying on motion.
- Do Mix mint, white and blush surfaces while keeping body text on quiet paper.
- Don't Nest cards or trap navigation in a floating pill bar.
- Don't Let dot or stripe patterns cross body text.
- Don't Smooth out all asymmetry; a slight compositional clash is part of the identity.
