Plakat

# Plakat

## Philosophy

Plakat is a maximalist pop system: it presses an interface like a limited-run poster — thick comic-ink keylines, ben-day halftone fields, adjacent slabs of hot pink, electric cyan and saturated yellow, and die-cut cards that stack like stickers on a wall. It keeps the loud, collectible, joyfully commercial character of pop art and Memphis-era exuberance while holding all of it inside a strict grid and one clear hierarchy so the noise always scans.

### Values

- graphic excess held together by legible structure
- consumer-culture brightness and instant readability
- playful, collectible, toy-shelf energy
- editorial collage layering with deliberate overlap
- high-contrast hierarchy that reads from across the room

### Anti-Values

- timid neutrality and invisible card edges
- austere restraint or quiet monochrome polish
- corporate pastel washes and frictionless sameness
- noise so dense that hierarchy disappears

### Visual Character

- Every major surface wears a bold black comic-ink keyline with a hard, un-blurred offset shadow, so cards read like cutout posters pasted on a wall rather than soft digital glass.
- Hero and header zones combine a page-wide ben-day halftone dot field, radiating burst rays, circular sticker badges and slightly rotated ribbon labels into a layered collage.
- Display type is oversized and uppercase (Bungee); supporting labels use compact monospace to mimic packaging callouts and magazine captions.
- Color blocking uses hot pink, electric cyan and saturated yellow in adjacent flat slabs against black-on-white, never tonal gradients.
- Containers use die-cut geometry: one clipped corner, circular KPI stickers that overlap the grid, and pill badges — the collectible-object rhythm.

- **Md**: 7px 7px 0 0 #141414

### Spacing

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

### Surfaces

- **Treatment**: paper / cutout poster
- **Card Style**: Bright white or candy-tinted cards over a page-wide ben-day halftone dot field, wrapped in bold black comic-ink keylines with hard offset shadows and one die-cut clipped corner.
- **Bg Pattern**: dots

### Borders

- **Default Width**: 3px
- **Accent Width**: 4px
- **Style**: solid
- **Character**: Comic-book ink contours: dark, assertive, always visible, wrapping whole surfaces to separate overlapping layers — never a timid grey edge and never a single-side accent edge.

### Motion

- **Duration**: 150ms
- **Easing**: cubic-bezier(0.2,0.9,0.2,1)
- **Philosophy**: snappy pressed-print — controls translate a few px while the hard offset shadow collapses

## Rules

### Composition

Build screens as editorial collages: one dominant hero slab, several overlapping die-cut support cards, and a rhythm of circular stickers, rotated ribbons and mini-panels anchored to shared baseline gutters so the deliberate chaos still scans cleanly.

### Hierarchy

Oversized Bungee headlines, saturated color bands, circular KPI stickers and black keylines make primary actions and numbers readable from a distance before body copy resolves. One button is clearly primary (hot-pink fill); the rest stay quieter but share one shape and height.

### Density

Keep density lively and high, but chunk information into bold blocks with visible gutters and breathing strips so the eye gets punctuation between intense color moments; never crowd one corner beside a starved void.

### Signature Patterns

- Die-cut cutout card — panels clip one corner and drop a hard offset shadow, reading like die-cut packaging instead of a rounded rectangle.
- Ribbon section header — headers sit on a slightly rotated cyan ribbon with an uppercase mono label and offset shadow.
- Circular KPI sticker — statistic callouts live in circular or pill badges that overlap adjacent cards and break the grid.
- Halftone + burst field — backgrounds carry a page-wide ben-day dot field with burst rays in hero zones.
- Pressed-print interaction — controls translate a few pixels on hover/press as their offset shadow collapses.

## Layout

### Grid

A 12-column desktop collage grid with one oversized primary column and one narrower utility column; allow intentional overlap but anchor each cluster to shared baseline gutters. Contained content caps and centers on ultra-wide; only the full-bleed hero spans 100vw.

### Breakpoints

Desktop keeps overlapping cards and floating stickers. Tablet (768-1024) is its own considered layout — a 2-column stack with reduced overlap and shallow ribbons, never the mobile column stretched wide. Mobile becomes a single column with badges tucked inside cards, oversized headlines shrinking with clamp() and wrapping (never clipping), nav wrapping to rows, and tables scrolling inside their own wrapper.

### Whitespace

Whitespace is the reset between bursts of color and type; breathing strips around each cluster keep the composition curated and density balanced across the canvas.

## Guidance

### Do

- Wrap every important surface in a black keyline with a hard offset shadow.
- Pair oversized Bungee display type with compact mono labels and badges.
- Overlap stickers, ribbons and circular metrics so some elements break the grid.
- Use saturated adjacent color slabs instead of quiet tonal palettes.
- Fully style every form control, including selects, checkboxes, switches and ranges.
- Keep buttons and chips on one line; body text at 17px+.

### Don't

- Rely on subtle grey borders or invisible card edges.
- Center everything into a polite, symmetrical dashboard.
- Mute the palette into corporate pastels or monochrome restraint.
- Use browser-default form controls.
- Let a headline clip at 390px, or pile noise so thickly that hierarchy disappears.

# Plakat

## Overview

Plakat is a maximalist pop system: it presses an interface like a limited-run poster — thick comic-ink keylines, ben-day halftone fields, adjacent slabs of hot pink, electric cyan and saturated yellow, and die-cut cards that stack like stickers on a wall. It keeps the loud, collectible, joyfully commercial character of pop art and Memphis-era exuberance while holding all of it inside a strict grid and one clear hierarchy so the noise always scans.

### Values

- graphic excess held together by legible structure
- consumer-culture brightness and instant readability
- playful, collectible, toy-shelf energy
- editorial collage layering with deliberate overlap
- high-contrast hierarchy that reads from across the room

### Anti-Values

- timid neutrality and invisible card edges
- austere restraint or quiet monochrome polish
- corporate pastel washes and frictionless sameness
- noise so dense that hierarchy disappears

### Visual Character

- Every major surface wears a bold black comic-ink keyline with a hard, un-blurred offset shadow, so cards read like cutout posters pasted on a wall rather than soft digital glass.
- Hero and header zones combine a page-wide ben-day halftone dot field, radiating burst rays, circular sticker badges and slightly rotated ribbon labels into a layered collage.
- Display type is oversized and uppercase (Bungee); supporting labels use compact monospace to mimic packaging callouts and magazine captions.
- Color blocking uses hot pink, electric cyan and saturated yellow in adjacent flat slabs against black-on-white, never tonal gradients.
- Containers use die-cut geometry: one clipped corner, circular KPI stickers that overlap the grid, and pill badges — the collectible-object rhythm.

## Components

### Composition

Build screens as editorial collages: one dominant hero slab, several overlapping die-cut support cards, and a rhythm of circular stickers, rotated ribbons and mini-panels anchored to shared baseline gutters so the deliberate chaos still scans cleanly.

### Hierarchy

Oversized Bungee headlines, saturated color bands, circular KPI stickers and black keylines make primary actions and numbers readable from a distance before body copy resolves. One button is clearly primary (hot-pink fill); the rest stay quieter but share one shape and height.

### Density

Keep density lively and high, but chunk information into bold blocks with visible gutters and breathing strips so the eye gets punctuation between intense color moments; never crowd one corner beside a starved void.

### Signature Patterns

- Die-cut cutout card — panels clip one corner and drop a hard offset shadow, reading like die-cut packaging instead of a rounded rectangle.
- Ribbon section header — headers sit on a slightly rotated cyan ribbon with an uppercase mono label and offset shadow.
- Circular KPI sticker — statistic callouts live in circular or pill badges that overlap adjacent cards and break the grid.
- Halftone + burst field — backgrounds carry a page-wide ben-day dot field with burst rays in hero zones.
- Pressed-print interaction — controls translate a few pixels on hover/press as their offset shadow collapses.

## 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-019f3dbe-fcec-7783-a8a6-24c3d4a48736/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 Wrap every important surface in a black keyline with a hard offset shadow.
- Do Pair oversized Bungee display type with compact mono labels and badges.
- Do Overlap stickers, ribbons and circular metrics so some elements break the grid.
- Do Use saturated adjacent color slabs instead of quiet tonal palettes.
- Do Fully style every form control, including selects, checkboxes, switches and ranges.
- Do Keep buttons and chips on one line; body text at 17px+.
- Don't Rely on subtle grey borders or invisible card edges.
- Don't Center everything into a polite, symmetrical dashboard.
- Don't Mute the palette into corporate pastels or monochrome restraint.
- Don't Use browser-default form controls.
- Don't Let a headline clip at 390px, or pile noise so thickly that hierarchy disappears.
