Gloaming

# Gloaming

## Philosophy

An interface language that reads like an illustrated dusk in motion: the screen is one continuous airbrushed skyscape, and content arrives as numbered scenes annotated by floating chrome-edged caption plaques rather than as interchangeable card grids.

### Values

- one continuous atmosphere instead of stacked equal-weight blocks
- narrative pacing through scene markers and measured reveals
- airbrushed gradient depth carrying meaning, not decoration
- annotations attached to moments like margin notes in a story
- luminous chrome accents used like highlighters on a deep dusk ground

### Anti-Values

- generic SaaS chrome and uniform card grids
- muddy washed pastels with no light source
- inked outline borders and accent edges on cards
- one shape stamped everywhere until it is wallpaper
- dense control-first layouts with no narrative framing

### Visual Character

- a deep indigo dusk ground lit by a single warm amber sun-glow that anchors the whole page
- soft sprayed gradient bands transition between scenes instead of hard horizontal rules
- floating caption plaques on frosted surface with one liquid-chrome highlight rim, never a hard border
- numbered chrome scene-markers on a fine vertical spine introduce each section
- oversized literary headlines with a single colour-pop highlighter word, never a serif italic swap

## Rules

### Composition

Compose the page as one continuous airbrushed skyscape divided into numbered scenes. Each scene carries one dominant focal moment plus a caption rail of floating plaques; avoid repetitive equal-weight blocks.

### Hierarchy

A numbered chrome scene-marker opens each section, an oversized literary headline with one colour-pop word sets the moment, then captions, callouts, and controls appear as frosted annotations anchored to the scene.

### Density

Airy and paced. Content appears in episodic clusters with generous vertical breathing room so each reveal stays readable and emotionally distinct.

### Signature

Numbered chrome scene-markers on a fine vertical spine; floating frosted caption plaques with a single liquid-chrome highlight rim (never a border); sprayed gradient bands transition between scenes; a single warm sun-glow anchors the dusk ground; one highlighter colour-pop word per headline.

## Layout

### Grid

A single-column narrative spine on mobile expanding to a 12-column dusk grid on desktop, alternating wide skyscape scenes with inset caption rails.

### Whitespace

Generous vertical space between scenes, moderate space inside plaques, deliberate negative space around the sun-glow focal point to pace the page-turn rhythm.

### Density

airy

### Responsive

Each breakpoint preserves scene sequencing; the skyscape stays continuous while plaque overlap and gradient-band intensity relax on smaller screens.

### Breakpoints

- **Mobile**: 0-767px
- **Tablet**: 768-1099px
- **Desktop**: 1100px+

## Guidance

### Do

- Design each section as a numbered scene with one clear emotional beat
- Let the airbrushed gradient ground carry depth and meaning, not just decorate
- Annotate scenes with floating frosted caption plaques and numbered markers
- Keep headlines literary with a single colour-pop highlighter word
- Use the warm sun-glow as the anchoring light source across scenes

### Don't

- Stack interchangeable cards with no narrative continuity
- Put outline borders or accent edges on cards
- Stamp one curved or wave shape everywhere until it is wallpaper
- Swap a serif headline between upright and italic for emphasis
- Compress content into dashboard density with no scene framing

### Accessibility

Maintain high contrast: warm near-white text on the deep indigo dusk ground; accent colours used as highlighters never as the sole signal; honour prefers-reduced-motion by skipping scene reveals.

## Imagery Direction

### Pairs With

chromahaze

### Summary

Airbrushed chrome-gradient dusk imagery: soft sprayed continuous tonal gradients with liquid-metal chrome highlights and atmospheric haze, lit by a single warm sun-glow.

### Subjects

- dusk skyscapes
- single luminous focal objects
- soft rounded distant cityscapes
- serene figures in atmospheric light

### Usage

Full-bleed hero skyscape behind the landing; full-frame airbrushed scene imagery inside scene sections; chrome highlight motifs echo the plaque rims.

## 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-019efdd8-0abe-7a33-af5b-e17b74d76a68/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.
