summary
A compact command language for a transient sleeper renting one night out of the rain. Software is treated as a narrow architectural compartment: manga gutters become berth seams, terminal cells become bedding labels, and every interaction reads as checking in, waiting out the weather, and leaving before nine.
values
Spatial compression over decorative abundance: identity comes from stacked berth proportions, narrow corridors and deliberately claustrophobic negative space.Terminal authenticity without hacker theatre: monospace carries only what the building itself would print — berth numbers, timers, weather.Private urban solitude: the voice is quiet, rented and inward-facing, meant for one person behind a drawn curtain.Manga structure as interface grammar: ink gutters, off-white caption slips, cropped panels and screentone restraint do the work that borders would.One light source: exactly one milk-white aperture per screen carries real light, and everything else reflects it.Embodied operation: the user is lying in a numbered module while the room, the weather and the checkout clock negotiate sleep.
anti-values
×No green code rain, neon cyberpunk skyline, vaporwave, or glitch theatrics.×No character art, mascots, or illustrated heroes that replace the interface.×No SaaS card grids, pill bars, boxed navigation, or rounded startup widgets.×No coloured edge rails, no accent strip down the side of a block, no borders at all.×No inflated type: body stays at 17px in a fine weight and only the display line is large.

treatment
Midnight ink ground with pod shells one step up; a single {colors.accent} aperture per screen is the only lit surface and the only element that casts a coloured glow.
card style
Never a card. A compartment: flat surface, 22px padding, the lower-right corner cut back 18px as a hatch chamfer, no border and no edge rail. Compartments never nest.
bg pattern
Vertical silver rain streaks over a character-cell grid, both held under ten percent opacity and dropped to near-zero wherever copy sits.

character
There are no borders. Blocks are separated by manga gutters — 2px of near-black ground between rows, 10-24px between sequences, and one 64-96px empty corridor per screen. The reserved seam token #FFFFFF14 is used only for hairline architectural seams, never as a card outline.
motion3 items
duration
180ms
easing
cubic-bezier(0.22,0.72,0.16,1)
philosophy
Motion is barely awake: a lamp comes on, a curtain slides a few pixels, a timer turns over. The landing is one scroll-controlled film of six scrubbed acts; entrances settle on an easing tail and every act holds long enough to be read.
rules
composition
Build screens as a rented interior rather than a dashboard: one dominant vertical stack of berths, one narrow service corridor, one private pane, and one vending-glow interruption. Panel weights are asymmetric — the berth column carries most of the mass and status strips tuck into the gutters. A stay strip frames the top and a rail frames the bottom so the operator feels enclosed.
hierarchy
First voice is numbered berth wayfinding in condensed uppercase; second is monospace prompts and weather telemetry; third is off-white caption slips. Hierarchy comes from panel placement, gutter thickness and the scarcity of light more than from size. Display type may be large but compressed and cropped by seams; the mid-tier compresses toward the 17px body.
density
Dense by intention: information clusters at 4-12px inside compartments while architectural gaps open to 64-96px. The interface should feel compact enough to sleep in, with one breathing void that reads as a dark corridor.
signature patterns
Berth bay stack: repeating horizontal bays, each with a milk pod tab pressed into its top-left corner and a lamp bar that lights when the curtain is drawn.Ink gutter: blocks are separated by ground showing through — 2px inside a sequence, 10-24px between sequences — so the language needs no borders and no edge rails.Hatch chamfer: the lower-right corner of every compartment is cut back at 45 degrees, 18-22px on compartments and 8-12px on controls, which is the only corner treatment in the language.Vending aperture: exactly one pale rectangle per screen carries real light and casts the only coloured glow; on the landing it is the climax, on the console it is the drinks cabinet.Rain pane: vertical silver streaks over a character-cell grid under ten percent opacity, wiped quiet behind every line of copy — a WebGL surface on the landing, the same texture in CSS elsewhere.Stay strip: a persistent occupancy readout — which berth, how long is left, what the weather is doing — that doubles as the film's progress instrument.
layout
grid
A 12-column shell. The landing runs one full-bleed stage per act. The console runs 5 / 4 / 3 — berth stack, weather and checkout queue, aperture and desk log. Gutters range from 2px interior seams to 96px architectural pauses.
breakpoints
Wide 1920+ caps and centres contained content while the film stage stays full-bleed. Desktop 1440 is the reference composition. Tablet 768-1180 is its own layout: the corridor becomes a horizontal ladder of hatches and the side panes stack under the main column. Phone 390-430 is a single column with the film re-choreographed for portrait, 140vh acts and 19vw display type.
whitespace
Claustrophobic by design: 4-12px cell gaps inside modules, 24-32px between sequences, and one 64-96px dark corridor per screen left deliberately empty to preserve the solitude.
guidance
do
  • Separate blocks with ink gutters and let the ground do the work of a border.
  • Keep one milk-white aperture per screen and let everything else sit in shell tones.
  • Set anything the building would print — berth numbers, timers, weather — in Fragment Mono.
  • Write copy as a scene inside the building: berths, curtains, coins, checkout hours.
  • Cut the lower-right corner of every compartment at the same angle and depth.
  • Quiet any pattern to near-zero wherever copy sits; full-density texture belongs to the empty areas.
avoid
  • Do not put a coloured strip down the edge of a block to show status; use a chip.
  • Do not round any corner — the hatch chamfer is the only corner treatment.
  • Do not trap navigation in a floating bar or a pill; let it sit on the page baseline.
  • Do not add green code rain, neon skylines, vaporwave, or glitch overlays.
  • Do not inflate body copy past 18px or set it in a heavy weight.
  • Do not introduce a third font family or a fourth accent colour.

## Layout

### Grid

A 12-column shell. The landing runs one full-bleed stage per act. The console runs 5 / 4 / 3 — berth stack, weather and checkout queue, aperture and desk log. Gutters range from 2px interior seams to 96px architectural pauses.

Phone 390-430 is a single column with the film re-choreographed for portrait, 140vh acts and 19vw display type.

### Whitespace

Claustrophobic by design: 4-12px cell gaps inside modules, 24-32px between sequences, and one 64-96px dark corridor per screen left deliberately empty to preserve the solitude.

## Guidance

### Do

- Separate blocks with ink gutters and let the ground do the work of a border.
- Keep one milk-white aperture per screen and let everything else sit in shell tones.
- Set anything the building would print — berth numbers, timers, weather — in Fragment Mono.
- Write copy as a scene inside the building: berths, curtains, coins, checkout hours.
- Cut the lower-right corner of every compartment at the same angle and depth.
- Quiet any pattern to near-zero wherever copy sits; full-density texture belongs to the empty areas.

### Don't

- Do not put a coloured strip down the edge of a block to show status; use a chip.
- Do not round any corner — the hatch chamfer is the only corner treatment.
- Do not trap navigation in a floating bar or a pill; let it sit on the page baseline.
- Do not add green code rain, neon skylines, vaporwave, or glitch overlays.
- Do not inflate body copy past 18px or set it in a heavy weight.
- Do not introduce a third font family or a fourth accent colour.

### Accessibility

Body and micro text hold 4.5:1 against their composited ground and display holds 3:1, measured behind the actual glyphs. Bright accents stay on swatches, chips and fills; accent-role TEXT on the milk aperture uses the dark ink variants #4A3A21 and #5C3617. Status is never colour alone — every chip carries a word. Focus rings are 2px sodium at 3px offset on every control. Tap targets are 44px. prefers-reduced-motion de-pins the film to the full settled document.

### Usage Context

Private network shells, night-shift and sleep-cycle operators, room and building control, anonymous message terminals, speculative device operating systems, and any product where solitude and temporary occupancy are the point.

## Imagery Direction

### Pairs With

nightpane

### Illustration Style

Photographic, never illustrated: a subject observed through a rain-beaded window at night, the wet glass between camera and subject.

### Hero Image Direction

One full-bleed full-screen plate at the top of the landing, served through --hero-image. A wet street at night with a single lit shutter, and the upper third left as calm dark sky so the wordmark can be composed over it rather than panelled onto it.

### Icon Style

Hand-drawn SVG line primitives at 1.5-2px stroke in the palette's own colours. No icon fonts, no emoji, no character glyphs in copy.

### Image Gen Prompts

- A wet street at night outside a small lodging house, one lit shutter as the only warm source, rain streaks across the frame, near-black midnight navy, calm dark sky in the upper third. NO text, NO letters, NO logos
- A narrow berth corridor receding to a single strip lamp, hatches in deep shadow on both sides, silver rain streaks over the frame. NO text, NO letters, NO logos
- The interior of a narrow sleeping berth looking out through a rain-beaded window at a dim city, one small warm reading lamp at the edge, sparse dim white and amber points only. NO text, NO letters, NO logos

### Plate Slots

# Amayadori

## Overview

A compact command language for a transient sleeper renting one night out of the rain. Software is treated as a narrow architectural compartment: manga gutters become berth seams, terminal cells become bedding labels, and every interaction reads as checking in, waiting out the weather, and leaving before nine.

### Values

- Spatial compression over decorative abundance: identity comes from stacked berth proportions, narrow corridors and deliberately claustrophobic negative space.
- Terminal authenticity without hacker theatre: monospace carries only what the building itself would print — berth numbers, timers, weather.
- Private urban solitude: the voice is quiet, rented and inward-facing, meant for one person behind a drawn curtain.
- Manga structure as interface grammar: ink gutters, off-white caption slips, cropped panels and screentone restraint do the work that borders would.
- One light source: exactly one milk-white aperture per screen carries real light, and everything else reflects it.
- Embodied operation: the user is lying in a numbered module while the room, the weather and the checkout clock negotiate sleep.

### Anti-Values

- No green code rain, neon cyberpunk skyline, vaporwave, or glitch theatrics.
- No character art, mascots, or illustrated heroes that replace the interface.
- No SaaS card grids, pill bars, boxed navigation, or rounded startup widgets.
- No coloured edge rails, no accent strip down the side of a block, no borders at all.
- No inflated type: body stays at 17px in a fine weight and only the display line is large.

### Visual Character

- clip-path hatch chamfers on the lower-right corner of every compartment, with border-radius pinned to 0 everywhere
- 2px near-black ink gutters as grid gap, doing the structural work a border would
- a single #EDE7D2 aperture per screen with a 0 0 40px rgba(237,231,210,.16) glow, the only coloured shadow in the language
- Fragment Mono at 12-13px with 0.09-0.16em tracking for every machine-printed value
- a rain-pane texture of vertical streaks over a character-cell grid at under 10% opacity, quieted to near-zero behind copy

### Lineage

> Generation 2 of Rain Capsule Command Shell: same rented-night identity, rebuilt to the current artifact standard and renamed to a legal one-word Maker's Mark.

## Layout

### Spacing Tokens

- **Base**: `8px`
- **Xs**: `4px`
- **Sm**: `8px`
- **Md**: `12px`
- **Lg**: `16px`
- **Xl**: `24px`
- **2xl**: `32px`
- **3xl**: `48px`
- **4xl**: `64px`
- **Step-8**: `96px`
- **Step-9**: `128px`

### Grid

A 12-column shell. The landing runs one full-bleed stage per act. The console runs 5 / 4 / 3 — berth stack, weather and checkout queue, aperture and desk log. Gutters range from 2px interior seams to 96px architectural pauses.

### Breakpoints

Wide 1920+ caps and centres contained content while the film stage stays full-bleed. Desktop 1440 is the reference composition. Tablet 768-1180 is its own layout: the corridor becomes a horizontal ladder of hatches and the side panes stack under the main column. Phone 390-430 is a single column with the film re-choreographed for portrait, 140vh acts and 19vw display type.

### Whitespace

Claustrophobic by design: 4-12px cell gaps inside modules, 24-32px between sequences, and one 64-96px dark corridor per screen left deliberately empty to preserve the solitude.

## Elevation & Depth

### Shadows

- **Sm**: 0 10px 24px rgba(0,0,0,0.45)
- **Md**: 0 18px 42px rgba(0,0,0,0.44), 0 0 34px rgba(134,167,184,0.08)
- **Lg**: 0 36px 90px rgba(0,0,0,0.62), inset 0 0 80px rgba(134,167,184,0.05)

## Shapes

### Rounded

- **None**: `0px`
- **Md**: `16px`
- **Lg**: `24px`
- **Full**: `9999px`

### Surfaces

- **Treatment**: Midnight ink ground with pod shells one step up; a single {colors.accent} aperture per screen is the only lit surface and the only element that casts a coloured glow.
- **Card Style**: Never a card. A compartment: flat surface, 22px padding, the lower-right corner cut back 18px as a hatch chamfer, no border and no edge rail. Compartments never nest.
- **Bg Pattern**: Vertical silver rain streaks over a character-cell grid, both held under ten percent opacity and dropped to near-zero wherever copy sits.

### Borders

- **Default Width**: 0px
- **Accent Width**: 0px
- **Style**: none
- **Character**: There are no borders. Blocks are separated by manga gutters — 2px of near-black ground between rows, 10-24px between sequences, and one 64-96px empty corridor per screen. The reserved seam token #FFFFFF14 is used only for hairline architectural seams, never as a card outline.

## Components

### Composition

Build screens as a rented interior rather than a dashboard: one dominant vertical stack of berths, one narrow service corridor, one private pane, and one vending-glow interruption. Panel weights are asymmetric — the berth column carries most of the mass and status strips tuck into the gutters. A stay strip frames the top and a rail frames the bottom so the operator feels enclosed.

### Hierarchy

First voice is numbered berth wayfinding in condensed uppercase; second is monospace prompts and weather telemetry; third is off-white caption slips. Hierarchy comes from panel placement, gutter thickness and the scarcity of light more than from size. Display type may be large but compressed and cropped by seams; the mid-tier compresses toward the 17px body.

### Density

Dense by intention: information clusters at 4-12px inside compartments while architectural gaps open to 64-96px. The interface should feel compact enough to sleep in, with one breathing void that reads as a dark corridor.

### Signature Patterns

- Berth bay stack: repeating horizontal bays, each with a milk pod tab pressed into its top-left corner and a lamp bar that lights when the curtain is drawn.
- Ink gutter: blocks are separated by ground showing through — 2px inside a sequence, 10-24px between sequences — so the language needs no borders and no edge rails.
- Hatch chamfer: the lower-right corner of every compartment is cut back at 45 degrees, 18-22px on compartments and 8-12px on controls, which is the only corner treatment in the language.
- Vending aperture: exactly one pale rectangle per screen carries real light and casts the only coloured glow; on the landing it is the climax, on the console it is the drinks cabinet.
- Rain pane: vertical silver streaks over a character-cell grid under ten percent opacity, wiped quiet behind every line of copy — a WebGL surface on the landing, the same texture in CSS elsewhere.
- Stay strip: a persistent occupancy readout — which berth, how long is left, what the weather is doing — that doubles as the film's progress instrument.

## 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-019ffc42-dc12-7223-b9f1-0fd37af7ae96/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 Separate blocks with ink gutters and let the ground do the work of a border.
- Do Keep one milk-white aperture per screen and let everything else sit in shell tones.
- Do Set anything the building would print — berth numbers, timers, weather — in Fragment Mono.
- Do Write copy as a scene inside the building: berths, curtains, coins, checkout hours.
- Do Cut the lower-right corner of every compartment at the same angle and depth.
- Do Quiet any pattern to near-zero wherever copy sits; full-density texture belongs to the empty areas.
- Don't Do not put a coloured strip down the edge of a block to show status; use a chip.
- Don't Do not round any corner — the hatch chamfer is the only corner treatment.
- Don't Do not trap navigation in a floating bar or a pill; let it sit on the page baseline.
- Don't Do not add green code rain, neon skylines, vaporwave, or glitch overlays.
- Don't Do not inflate body copy past 18px or set it in a heavy weight.
- Don't Do not introduce a third font family or a fourth accent colour.

### Accessibility

Body and micro text hold 4.5:1 against their composited ground and display holds 3:1, measured behind the actual glyphs. Bright accents stay on swatches, chips and fills; accent-role TEXT on the milk aperture uses the dark ink variants #4A3A21 and #5C3617. Status is never colour alone — every chip carries a word. Focus rings are 2px sodium at 3px offset on every control. Tap targets are 44px. prefers-reduced-motion de-pins the film to the full settled document.

### Usage Context

Private network shells, night-shift and sleep-cycle operators, room and building control, anonymous message terminals, speculative device operating systems, and any product where solitude and temporary occupancy are the point.

## Imagery Direction

### Pairs With

nightpane

### Illustration Style

Photographic, never illustrated: a subject observed through a rain-beaded window at night, the wet glass between camera and subject.

### Hero Image Direction

One full-bleed full-screen plate at the top of the landing, served through --hero-image. A wet street at night with a single lit shutter, and the upper third left as calm dark sky so the wordmark can be composed over it rather than panelled onto it.

### Icon Style

Hand-drawn SVG line primitives at 1.5-2px stroke in the palette's own colours. No icon fonts, no emoji, no character glyphs in copy.

### Image Gen Prompts

- A wet street at night outside a small lodging house, one lit shutter as the only warm source, rain streaks across the frame, near-black midnight navy, calm dark sky in the upper third. NO text, NO letters, NO logos
- A narrow berth corridor receding to a single strip lamp, hatches in deep shadow on both sides, silver rain streaks over the frame. NO text, NO letters, NO logos
- The interior of a narrow sleeping berth looking out through a rain-beaded window at a dim city, one small warm reading lamp at the edge, sparse dim white and amber points only. NO text, NO letters, NO logos

### Plate Slots

- **--Hero-Image**: plate-1-arrival — full-bleed rainy street, scene 1 (the house hero slot; scene 1 has no separate --plate-N)
- **--Plate-2**: plate-2-desk — unattended night desk and key board behind wet glass, scene 2
- **--Plate-3**: plate-3-corridor — berth corridor receding to one strip lamp, scene 3
- **--Plate-4a**: plate-4a-glass-wet — TWIN A: the pane running with rain streaks, scene 4
- **--Plate-4b**: plate-4b-glass-fog — TWIN B: the same pane fogged with condensation, scene 4
- **--Plate-5**: plate-5-berth — inside the berth, window over the dim city, scene 5 (climax)
- **--Plate-6**: plate-6-dawn — curtain slit flooding with 09:00 daylight, scene 6
