Aerial

# Aerial

## Philosophy

Aerial is a late-night broadcast design language: it dresses an interface like a warm analog channel picked up after midnight — sodium-amber phosphor over deep indigo, broadcast frames that tune in through a vertical-hold roll, a frequency dial with a glowing cyan needle, and a station ident that never sleeps. Where a control-room reading of the cathode tube goes cold and green, Aerial goes warm and human: the glow of a tube TV in a dark room, not a mission console. Everything is a station you tune into.

### Values

- warm late-night broadcast intimacy over clinical control-room coldness
- everything is a station you tune into — channels, not stacked panels
- the value reads before the label; numerics carry the brightest sodium bloom
- framing is a coloured ribbon and a phosphor bloom, never a grey outline
- status spoken in plain broadcast language: live, cued, recording, locked

### Anti-Values

- cold green mission-console telemetry
- grey-bordered boxed widgets and cards-in-cards
- flat hierarchy with everything equally bright
- scroll cues and down-arrow indicators
- decoration without an idea

### Visual Character

- every section opens with a tuning ribbon: a channel chip, a station name, and a frequency dial with a glowing cyan needle
- broadcast frames carry a sodium-to-magenta ribbon down the left edge and a faint horizontal roll-bar seam — the picture settling into vertical hold
- a rainbow test-pattern channel band runs across the top and bottom edges like station colour bars
- deep indigo-violet ground lit only by phosphor; warm-tuned neutrals, never cold grey
- interaction brightens the sodium bloom rather than moving or reshaping the control

- **Philosophy**: frames tune into view with a gentle rise like a picture finding vertical hold; hover and focus brighten the bloom, never bounce or reshape

## Rules

### Composition

Compose screens as a broadcast schedule: a station ident bar, a full-viewport hero you tune into, then channels stacked top to bottom. Each region is a broadcast frame opened by a tuning ribbon (channel chip + station name + frequency dial). Never nest a frame in a frame; never box navigation into a floating pill.

### Hierarchy

Numerics carry the highest contrast and the brightest sodium bloom; the value reads before its label. Labels live quiet in DM Mono. Magenta means live, cyan means cued/locked, sodium means recording. Body copy stays secondary.

### Density

Schedule density — substantial information per frame, separated by obvious frame gaps and contrasting indigo underlays so it reads engineered, never crowded.

### Signature

The tuning ribbon — a channel chip, a station name, and a frequency dial with a glowing cyan needle — opening a broadcast frame: sodium-to-magenta left ribbon, faint horizontal roll-bar seam, scanline roll overlay over display zones.

## Layout

### Grid

Desktop dashboard: a left tuner rail (a breathing nav list, not a boxed widget) and a main stack of broadcast frames in a 12-column rhythm. Landing: full-bleed hero, then full-width channel sections. Tablet collapses the rail to a top strip; phone is a single column with each tuning ribbon stacked above its frame.

### Whitespace

Broadcast spacing: tight within a frame's data, generous between framed channels, protected around the hero.

### Density

engineered schedule density — full but never crowded

### Responsive

Renders from ~390px to 2560px+. Non-essential table columns (host) and nav links drop on mobile rather than overflow; the full-bleed hero spans 100vw while contained content is capped and centred on ultra-wide.

### Breakpoints

- **Xl**: 1200px
- **Lg**: 1024px
- **Md**: 768px
- **Sm**: 480px

## Guidance

### Do

- Let sodium-amber be the resting glow; reserve magenta for live and cyan for cued/locked.
- Open every region with a tuning ribbon keyed to a channel.
- Use DM Mono channel codes, frequencies, and timestamps for broadcast credibility.
- Keep numerics largest and brightest — the value reads before the label.
- Apply scanline roll overlays to display zones, not every surface.

### Don't

- Do not go cold or green; this is a warm late-night channel, not a mission console.
- Do not box navigation into a floating pill or nest a frame inside a frame.
- Do not flatten hierarchy by making all text equally bright.
- Do not use grey borders; the ribbon and the bloom are the framing.
- Do not add scroll cues or down-arrow indicators.

### Accessibility

Body 17px+, numerics larger and brightest; high contrast (phosphor white on deep indigo, never dark-on-dark). Every control explicitly styled with a visible cyan-bloom focus state. Status is never carried by colour alone — pills pair colour with a DM Mono label and an inline-SVG glyph. Motion respects prefers-reduced-motion; the settled page renders with no JavaScript.

## Imagery Direction

### Pairs With

cathode

### Summary

Imagery captured off a glowing cathode-ray tube — baked-in scanlines, phosphor bloom, chromatic-aberration fringing and a gentle barrel curve — applied to a broadcast world: rooftop aerials, transmission waves, test patterns and station idents. Warm sodium-amber key with hot magenta and tuner cyan accents over deep indigo. Full-bleed phosphor output with no monitor bezel.

### Subjects

- rooftop television broadcast aerials against transmission waves
- concentric carrier-wave and signal-propagation rings
- test-pattern colour bars and station idents
- tuning dials and frequency scales

### Usage

The landing hero swaps via background-image: var(--hero-image). Keep the overlay legible over the image; never an img tag.

# Aerial

## Overview

Aerial is a late-night broadcast design language: it dresses an interface like a warm analog channel picked up after midnight — sodium-amber phosphor over deep indigo, broadcast frames that tune in through a vertical-hold roll, a frequency dial with a glowing cyan needle, and a station ident that never sleeps. Where a control-room reading of the cathode tube goes cold and green, Aerial goes warm and human: the glow of a tube TV in a dark room, not a mission console. Everything is a station you tune into.

### Values

- warm late-night broadcast intimacy over clinical control-room coldness
- everything is a station you tune into — channels, not stacked panels
- the value reads before the label; numerics carry the brightest sodium bloom
- framing is a coloured ribbon and a phosphor bloom, never a grey outline
- status spoken in plain broadcast language: live, cued, recording, locked

### Anti-Values

- cold green mission-console telemetry
- grey-bordered boxed widgets and cards-in-cards
- flat hierarchy with everything equally bright
- scroll cues and down-arrow indicators
- decoration without an idea

### Visual Character

- every section opens with a tuning ribbon: a channel chip, a station name, and a frequency dial with a glowing cyan needle
- broadcast frames carry a sodium-to-magenta ribbon down the left edge and a faint horizontal roll-bar seam — the picture settling into vertical hold
- a rainbow test-pattern channel band runs across the top and bottom edges like station colour bars
- deep indigo-violet ground lit only by phosphor; warm-tuned neutrals, never cold grey
- interaction brightens the sodium bloom rather than moving or reshaping the control

## 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-019efa5c-f0a6-7b83-bed3-759ffd500de2/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.
