Tobari

# Tobari

## Philosophy

Tobari — the veil of night that falls over a sequential page — stages an interface the way a manga page is read after the lights go down: as a sequence of spotlit panels on the dark. Where the daytime page reads black on white, Tobari reads off-white kozo on deep indigo night. Structure is the drama. Each major region is a spotlit koma: a lifted indigo panel carrying a full sumi-ink frame and an offset solid-ink shadow block, so it reads printed and stacked rather than soft and floating. A docked uppercase-mono caption strip names the beat. Wide, structural dark gutters between frames are the pause — the ma — and never collapse to save a row. The asymmetric grid mixes a tall portrait panel and a wide panoramic one, and the focal frame carries the single vermilion spotlight: the beat the whole page was paced toward. Imagery is mokuhanga woodblock — carved sumi contours, a flat indigo field, one vermilion spot — the same grammar that governs the colour, so picture and interface read as one printed night.

### Values

- Spotlit framing: every region is a lit koma with a full ink frame and an offset print-shadow, so the reader knows exactly where to look.
- The gutter is the silence: wide dark intervals between frames carry the pause that makes a reveal land.
- One vermilion beat: the single spot of vermilion marks the focal moment per view, reserved like a highlighter.
- Read on the dark: a deep-indigo night ground, not white — drama by contrast, off-white kozo text for legibility.
- Sequential readability: size, caption, and adjacency imply an order of attention before any menu does.
- Printed material honesty: frames and offset shadow blocks feel inked and stacked, never soft glass or vague gradient.

### Anti-Values

- A white or cream surface anywhere — the language lives on the dark.
- A single accent edge or top-rule standing in for a full four-side frame.
- Borderless dissolving panels, soft glassmorphism, or vague gradients.
- Even card grids that flatten pacing, or gutters that collapse on mobile.
- Emoji or symbol glyphs on controls; novelty comic gimmicks like constant speech bubbles.

- **Philosophy**: settled-by-default; panels rise in on scroll and the night settles via a gentle hero parallax; respects prefers-reduced-motion

## Rules

### Composition

Compose each view as a readable sequence of spotlit koma panels separated by wide structural gutters. Major panels span multiple rows or columns; adjacency implies the order of reading. At least one region per view is a quiet release. Gutters stay visibly wide at every breakpoint.

### Hierarchy

Panel scale first, then the docked caption strip, then the carved-serif heading, then the single vermilion spotlight on the focal frame. A region looks framed and authored before it looks interactive.

### Density

Alternate dense data panels with open breathing panels; never run high-detail frames edge to edge across the whole canvas.

### Signature

Every major panel is a lit koma — a full 3px sumi frame plus an offset solid-ink shadow block (focal: vermilion offset). A docked uppercase-mono caption strip names the beat. The asymmetric grid carries a tall portrait panel and a wide panoramic one. The focal frame holds the single vermilion spot. One speech-bubble margin note appears at most once per view for human guidance.

## Layout

### Grid

Desktop uses an asymmetric multi-fr composition with mixed spans (a tall portrait scene panel + wide panoramic panels); tablet keeps one hero frame; mobile becomes a stacked single-column panel reel with kept gutters and reordered narrative priority. minmax(0,1fr) tracks and min-width:0 children keep grids from blowing out.

### Whitespace

Oversized dark gutters are the silence between beats — a narrative pause, not leftover space. They tighten but never vanish on mobile.

### Density

Paced: compressed data frames balanced by open release frames.

### Responsive

Renders from ~390px mobile to 2560px+ ultra-wide; contained content caps and centres on ultra-wide, only the full-bleed hero spans 100vw; stacks to a single column on mobile with no horizontal overflow.

### Breakpoints

- **Ultrawide**: 1600px+
- **Desktop**: 981px-1599px
- **Tablet**: 641px-980px
- **Mobile**: <=640px

## Guidance

### Do

- Keep the deep-indigo night ground; frame every koma on all four sides.
- Reserve vermilion for one spotlight beat per view; use indigo as the cool register and pine for success.
- Dock uppercase-mono caption strips to name beats and modes.
- Hold the gutters wide; let at least one frame breathe.
- Draw imagery from the mokuhanga technique — carved contours, flat indigo field, one vermilion spot.

### Don't

- Introduce a white or cream surface, or a soft glassmorphic panel.
- Replace a full frame with a single accent edge or top-rule.
- Round corners off the {0,16,24,9999} set, or use vague gradients.
- Nest cards, or collapse the gutters on small screens.
- Put emoji or symbol glyphs on controls or in copy.

### Accessibility

Off-white kozo on deep indigo clears WCAG AA for body text; high-contrast pairings (kozo-on-sumi, vermilion-on-kozo) carry emphasis. Vermilion is never the only signal — status also carries a mono label. Focus is a visible vermilion frame on every control. Motion is gated on prefers-reduced-motion.

## Imagery Direction

### Pairs With

mokuhanga

### Summary

Mokuhanga woodblock nocturnes on the dark: flat carved sumi contours, a muted indigo field, one vermilion spot, woodgrain inside the colour blocks, on off-white kozo paper. Picture and interface read as one printed night.

### Subjects

- a breaking wave under a dark mountain at night
- a lantern street after dusk
- a last train under a low crescent moon
- a quiet harbour gate

### Usage

One full-bleed hero nocturne on the landing; framed scene panels (the 'now lit' koma) inside embodiment and dashboard. Never the apparatus (no press, block, or paper sheet as subject); no text, letters, or logos in the image.

## 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-019ef67c-4756-7d41-b3b5-2ee4b0db319e/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 Keep the deep-indigo night ground; frame every koma on all four sides.
- Do Reserve vermilion for one spotlight beat per view; use indigo as the cool register and pine for success.
