Chase

# Chase

## Philosophy

Chase treats software like a hand-set page locked in its iron frame. A warm bone-paper field carries dense lampblack ink, ruled grids, captioned panels, and authored marginalia. A chase is the rigid frame a compositor locks a set page into with quoins so the whole form lifts as one; that lockup is the one ownable idea — content is set, then locked, every panel a captioned block aligned to black rules, the whole spread lifting as one rigid object. Ink carries the decisions; colour is reserved for one mark at a time.

### Values

- Ink as authority — decisions are set in dense black, never merely tinted.
- The page is the interface — columns, gutters, captions, folios, and rules instead of floating app chrome.
- Line weight before colour — 4px decision strokes, 2px frames, 1px hairlines set order first.
- Two ink marks, no more — oxblood for one active correction, cobalt for one reference, like a proofreader's pencil.
- Restraint over ornament — large quiet paper zones; whitespace is margin, not absence.
- Fine-art tactility — generated paper grain and squared offset ink-shadows give material presence while controls stay precise.

### Anti-Values

- Generic SaaS cards with soft shadows, large radii, pastel washes, or glass.
- Defaulting to a white ground; leaving loose, unframed, uncaptioned content.
- Colour-only hierarchy, or a third and fourth accent crowding the two ink marks.
- Decorative doodles, fake hand-drawn scribbles, or symbol glyphs in copy.
- A single accent edge stamped on a card, nested cards, or navigation trapped in a pill bar.

### Radii

- **None**: 0

- **Md**: 2px
- **Full**: 9999px

### Shadows

- **Sm**: 2px 2px 0 #0B0A06
- **Md**: 4px 4px 0 #0B0A06

### Spacing

- **Base**: 8px
- **Scale**: ["4px","8px","12px","16px","24px","32px","48px","64px","96px","128px"]

### Surfaces

- **Bg Pattern**: generated paper grain (layered radial + linear gradients, no image)
- **Card Style**: Flat warm paper panels with visible grain, squared 2px corners, black editorial rules, emphasis via a 4px top stroke and an offset registration ink-shadow.
- **Treatment**: paper

### Borders

- **Default Width**: 1px
- **Frame Width**: 2px
- **Accent Width**: 4px
- **Style**: solid
- **Character**: Borders are printed rules: 1px hairlines divide reading, 2px lines frame decisions, 4px strokes mark primary editorial emphasis. Black, never grey; never a single decorative accent edge.

### Motion

- **Duration**: 150ms
- **Easing**: cubic-bezier(0.2, 0, 0.1, 1)
- **Philosophy**: Deliberate, near print-static — the settled page is the default and shows with no JavaScript; JS adds a one-shot CSS entrance that always finishes on its own. Respects prefers-reduced-motion.

## Rules

### Composition

Compose on an editorial grid before any component decisions: a narrow folio rail, a main authored column, and a marginalia annotation column, aligned to black vertical rules; let at least one quadrant stay quiet paper. Prefer horizontal rules, vertical gutters, and caption tabs over rounded cards. Iconography is scarce and text-led.

### Hierarchy

Hierarchy runs from 4px black decision strokes to 2px frames to 1px hairline rules, then typography. Headings use Libre Baskerville with tight leading; captions and data use IBM Plex Mono uppercase; body uses Source Serif 4. Oxblood marks one active item and cobalt one reference — never decorate multiple unrelated elements.

### Density

Compact inside panels (8-16px internal rhythm), spacious between them (48-96px desktop gutters). A screen reads like an edited broadsheet proof: precise islands of information on a quiet paper ground.

### Signature

The lockup: every major panel carries a uppercase-mono caption tab pinned to its top-left, started by a 4px ink stub and carried to the gutter by a 1px hairline; emphasis panels add a 4px top stroke and a squared offset ink-shadow; the folio/main/marginalia spread collapses to one ruled column on mobile.

## Layout

### Grid

Desktop uses a max-width ~1320px spread: a ~72px folio rail, a 1fr main column, and a ~320px marginalia column separated by 24-32px gutters and black vertical rules. Panels use internal editorial subgrids when needed.

### Whitespace

Whitespace is paper margin, not generic emptiness. Generous outer padding (24px mobile, 40px tablet, 64-96px desktop) with deliberate quiet zones beside dense captioned panels.

### Density

Compact editorial density: high information per panel with strict captioning, offset by large paper margins so the interface stays calm and literary.

### Responsive

390px: one ruled column, 16-24px gutters, 44px+ controls, captions stay visible, decorative rail hidden. 768px: two columns with marginalia beneath. 1440px+: full folio/main/margin spread; only the hero spans 100vw, contained content caps and centres.

### Breakpoints

- **Mobile**: <=640px
- **Tablet**: 641-1024px
- **Desktop**: >=1025px

## Guidance

### Do

- Set the page on a warm paper ground with dense black ink before any accent.
- Give every panel an authored caption tab; write microcopy like proof notes.
- Build hierarchy with 4px / 2px / 1px black rules, then typography, then one ink mark.
- Reserve oxblood for one active state and cobalt for one reference; keep quiet paper zones.
- Use squared 2px corners and offset ink-shadows for printed materiality.
- Style every form control explicitly in the ruled-paper grammar — no browser defaults showing.

### Don't

- Do not default to white or use pastel washes, soft shadows, large radii, or glass.
- Do not put a single accent edge on a card, nest cards, or trap navigation in a pill bar.
- Do not rely on colour alone for hierarchy or add a third and fourth accent.
- Do not add decorative doodles, fake hand-drawn icons, or symbol glyphs in copy.
- Do not centre every block; preserve editorial asymmetry and quiet margins.

### Accessibility

Maintain high contrast between black ink and warm paper. Accent states also carry border weight and a label, never colour alone. Body text 17px+, table rows 14.5px+, controls 44px+ tall on touch, focus states a visible 2px or 4px ink ring with offset. Respect prefers-reduced-motion.

## Imagery Direction

### Pairs With

lampblack

### Summary

Dense fine-art lampblack ink drawing on a warm bone-paper field with visible fiber grain: loaded sumi-e brush masses with crisp pen-and-nib contour and cross-hatching, one small restrained accent ink mark, severe editorial restraint and generous quiet negative space. Subjects come from the composing room and the printed page.

### Subjects

- letterpress composing stick with loose metal type
- an open hand-set page proof with column rules
- a wooden quoin locking a type chase
- a type case drawer
- an inked press platen
- a galley of standing matter

### Usage

One full-bleed landing hero in the Lampblack technique, with quiet negative space reserved for the overlay. Imagery is fine-art ink, never used for the thumbnail (the embodiment is).

# Chase

## Overview

Chase treats software like a hand-set page locked in its iron frame. A warm bone-paper field carries dense lampblack ink, ruled grids, captioned panels, and authored marginalia. A chase is the rigid frame a compositor locks a set page into with quoins so the whole form lifts as one; that lockup is the one ownable idea — content is set, then locked, every panel a captioned block aligned to black rules, the whole spread lifting as one rigid object. Ink carries the decisions; colour is reserved for one mark at a time.

### Values

- Ink as authority — decisions are set in dense black, never merely tinted.
- The page is the interface — columns, gutters, captions, folios, and rules instead of floating app chrome.
- Line weight before colour — 4px decision strokes, 2px frames, 1px hairlines set order first.
- Two ink marks, no more — oxblood for one active correction, cobalt for one reference, like a proofreader's pencil.
- Restraint over ornament — large quiet paper zones; whitespace is margin, not absence.
- Fine-art tactility — generated paper grain and squared offset ink-shadows give material presence while controls stay precise.

### Anti-Values

- Generic SaaS cards with soft shadows, large radii, pastel washes, or glass.
- Defaulting to a white ground; leaving loose, unframed, uncaptioned content.
- Colour-only hierarchy, or a third and fourth accent crowding the two ink marks.
- Decorative doodles, fake hand-drawn scribbles, or symbol glyphs in copy.
- A single accent edge stamped on a card, nested cards, or navigation trapped in a pill bar.

## 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-019efac2-e57c-7310-8af0-b777b1af94d5/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.
