Klieg

# Klieg

## Philosophy

Klieg is a wayfinding interface language built from the way a dense night street already works. On a crowded neon corridor you scan colour, number, and the direction a sign points, then move — you never read paragraphs. Klieg turns that into structure: content lives in luminous sign-towers on a deep blue-black night ground, and three bright lights — magenta, cyan, amber — do all the signalling, used like highlighters. Glow, bloom, and wet-street reflection carry the brightness so the chrome stays quiet underneath.

### Values

- a dense night street as a way to move through data — scan by colour and number, then read
- the marquee column is the structure: every surface is a sign-tower with one luminous spine that recolours by role
- three accents used like highlighters on a deep night ground — magenta to signal, cyan to route, amber to mark what is live
- the night is the ground, not a theme switch; glow and reflection carry the brightness while the chrome stays quiet

### Anti-Values

- defaulting to white or washing the ground pale — the night is the point
- a second loud accent, or flooding a surface with colour
- boxed-in navigation trapped in a floating pill, or nested cards
- long body copy as the primary hierarchy device instead of scan-first signage

### Visual Character

- The marquee column: every primary surface is a tall sign-tower with one luminous left spine and three-to-five compressed modules stacked behind it; the spine recolours by role so the same shape carries traffic, revenue, or an alert.
- A deep blue-black night ground against which magenta, cyan and amber read as bright highlighter marks; structure comes from the lit spine and hard gutters, never from grey borders.
- Strong grotesque display type (Archivo, uppercase, tight tracking) that reads like signage at distance, over calm 17px Inter body and JetBrains Mono labels behaving like sign metadata; one headline word carries a colour-pop, never a serif/italic swap.
- One live inset screen per view — a billboard-within framed on-air, driven by the swappable night-photo hero — plus glowing status lights, transit chips, and magenta-to-amber meters that stand in for any stat row.

- **Philosophy**: boards switching on down a corridor; settled lit state is the default, reveal is added on top and reduced-motion renders lit

## Rules

### Composition

Compose as a night corridor: primary content lives in luminous sign-towers (marquee columns) on a deep blue-black ground, supporting detail rides transit chips, status lights, and one live inset screen. Surfaces are carved apart by lit spines and hard gutters, not grey borders.

### Hierarchy

Scan-first: one oversized display number or word, then dense mono labels and metadata. Users read by colour, number, and direction before any paragraph.

### Density

High density kept legible — each surface is a bounded sign-tower with one spine and one hairline per row; the scene feels packed with signals yet orchestrated.

### Signature

The marquee column — a tall surface with one luminous left spine and 3–5 compressed modules; the spine recolours by role (magenta signal, cyan route, amber live) so the same shape carries any kind of data.

## Layout

### Grid

Desktop content caps and centres at 1200px with a dominant column of sign-towers; the full-bleed night-photo hero and bands span 100vw. Tablet keeps stacked towers; mobile becomes a single dense column of towers with the sign-rail collapsed to a wrapped nav.

### Whitespace

Whitespace is a hard gutter and separator between towers, not calm atmosphere — breathing room exists inside labels and between stacks while the overall scene stays packed with signals.

### Density

high

### Responsive

Every artifact renders from ~390px to 2560px+. Oversized display/hero headlines are viewport-sized (clamp) and wrap — never clipping or running off the 390px edge. On mobile, towers stack single-column and non-essential nav collapses.

### Breakpoints

- **Mobile**: 0px
- **Tablet**: 760px
- **Desktop**: 1180px

## Guidance

### Do

- Build surfaces as sign-towers with one luminous spine; recolour the spine by role.
- Keep three accents on a deep night ground; let glow and wet-street reflection carry the brightness.
- Use scan-first hierarchy: one big number or word, then dense mono labels.
- Place one live inset screen per view, driven by the swappable hero image.

### Don't

- Default to white or wash the ground pale.
- Add a second loud accent or flood a surface with colour.
- Box the navigation into a floating pill or nest cards.
- Lean on long body copy as the primary hierarchy device.

### Accessibility

Near-white text on a deep night ground holds high contrast; semantic colour is carried by a labelled status light plus text, never colour alone; focus rings are a visible cyan ring; motion is gated and honours prefers-reduced-motion.

## Imagery Direction

### Pairs With

halation-bloom

### Summary

Long-exposure night photography in the Halation technique: bloom swells around every light, wet ground mirrors the neon, the subject's edges glow against deep dark. Magenta, cyan and amber read as highlighter marks on the night.

### Subjects

- a rain-soaked neon corridor of sign-towers
- a single object rim-lit by night signage
- a night-street portrait lit by neon
- a wet boulevard with reflected light streaks

### Usage

One full-bleed night-photo hero per landing; one live inset screen per major surface, driven by --hero-image. Keep the brightest signage massed to one side and a calmer dark zone for overlaid headlines.

# Klieg

## Overview

Klieg is a wayfinding interface language built from the way a dense night street already works. On a crowded neon corridor you scan colour, number, and the direction a sign points, then move — you never read paragraphs. Klieg turns that into structure: content lives in luminous sign-towers on a deep blue-black night ground, and three bright lights — magenta, cyan, amber — do all the signalling, used like highlighters. Glow, bloom, and wet-street reflection carry the brightness so the chrome stays quiet underneath.

### Values

- the night is the ground, not a theme switch; glow and reflection carry the brightness while the chrome stays quiet

### Anti-Values

- a second loud accent, or flooding a surface with colour
- boxed-in navigation trapped in a floating pill, or nested cards
- long body copy as the primary hierarchy device instead of scan-first signage

### Visual Character

- The marquee column: every primary surface is a tall sign-tower with one luminous left spine and three-to-five compressed modules stacked behind it; the spine recolours by role so the same shape carries traffic, revenue, or an alert.
- A deep blue-black night ground against which magenta, cyan and amber read as bright highlighter marks; structure comes from the lit spine and hard gutters, never from grey borders.
- Strong grotesque display type (Archivo, uppercase, tight tracking) that reads like signage at distance, over calm 17px Inter body and JetBrains Mono labels behaving like sign metadata; one headline word carries a colour-pop, never a serif/italic swap.

## 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-019efd9e-f923-72d0-991e-93036552815c/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 Build surfaces as sign-towers with one luminous spine; recolour the spine by role.
- Do Keep three accents on a deep night ground; let glow and wet-street reflection carry the brightness.
- Do Use scan-first hierarchy: one big number or word, then dense mono labels.
- Do Place one live inset screen per view, driven by the swappable hero image.
- Don't Default to white or wash the ground pale.
- Don't Add a second loud accent or flood a surface with colour.
- Don't Box the navigation into a floating pill or nest cards.
- Don't Lean on long body copy as the primary hierarchy device.
