Selvage

# Selvage

## Philosophy

Selvage keeps the discipline of a Japanese stationery planner — ruled columns, edge labels, open margins, bounded illustration — but works every surface in woven linen and embroidery floss. The grid is a real warp-and-weft weave, section labels are stitched fabric tabs that protrude from a panel's edge, dividers are running stitches, and pictures live inside an embroidery hoop. Structure is woven in, never drawn on top; warmth comes from honest material and three muted flosses used like highlighters on a calm linen ground.

### Values

- planner discipline expressed as a real woven warp-and-weft grid
- section labels as stitched selvedge tabs, findable at a glance
- illustration kept bounded inside an embroidery hoop or framed window
- open margins for stitched annotations, timestamps and owners
- one floss accent per view, used like a highlighter on linen

### Anti-Values

- atmospheric gradients or pastel washes replacing structure
- a single accent edge stamped on every card
- imagery bleeding across the controls that run the studio
- all three flosses spread across the chrome at once
- soft blobs that erase the woven, planner-square feel

### Visual Character

- the warp-rule grid: a fine warp-and-weft thread grid runs through the ground and every panel, so the module reads as cloth
- selvedge tabs: section names are full-pill fabric tabs dyed madder, indigo or saffron that protrude from a panel's top edge
- running-stitch rules: rows, columns and panel frames divide on dashed running stitches instead of hard lines
- the embroidery hoop: illustration is always bounded inside a circular hoop or a 16:10 framed window, never bleeding free
- stitched marginalia: timestamps, owners and helper copy tuck into the margin as quiet mono annotations

### Radii

- **None**: 0
- **Sm**: 16px

- **Lg**: 24px
- **Full**: 9999px

### Shadows

- **Sm**: 0 1px 0 rgba(255,255,255,0.6) inset, 0 6px 16px rgba(30,42,68,0.06)
- **Md**: 0 1px 0 rgba(255,255,255,0.6) inset, 0 14px 30px rgba(30,42,68,0.07)

### Surfaces

- **Treatment**: woven-textile

- **Easing**: cubic-bezier(0.2,0.8,0.2,1)
- **Philosophy**: deliberate: panels settle upward on enter like cloth laid on a table; settled state is the no-JS default

## Rules

### Composition

Compose every region as a piece of cloth on a warp-and-weft grid: generous margins, ruled subdivisions, and selvedge-tab labels protruding from panel edges, leaving the margin open for notes.

### Hierarchy

Hierarchy comes from selvedge tabs, running-stitch subdivisions, a quiet serif, mono numerals, and one floss accent on the live element — not from large scale shifts.

### Density

Moderately dense. Information can be plentiful, but every cluster sits inside a labelled woven panel with visible spacing and stitched micro-labels.

### Signature

The selvedge tab + warp-rule grid: every panel is woven cloth with a stitched fabric tab woven into its edge; dividers and the headline highlighter are running stitches.

## Layout

### Grid

A 12-column desk-page grid on desktop, collapsing to a single column under 760px while preserving margin gutters and the woven warp-weft subdivisions inside modules.

### Whitespace

Generous perimeter margins, moderate inter-panel spacing, small internal padding always padded above titles; the open margin is part of the composition.

### Density

comfortable-to-moderate

### Responsive

Single column under 760px; the warp grid and selvedge tabs persist at every width; tables scroll inside their panel; hoops and framed windows move below primary content rather than disappearing; the hero headline shrinks with clamp() and wraps, never clipping at 390px.

### Breakpoints

- **Sm**: 390px
- **Md**: 760px
- **Lg**: 1000px
- **Xl**: 1700px

## Guidance

### Do

- Let the woven warp-and-weft grid show through the ground and every panel.
- Label sections with stitched selvedge tabs; keep them short like notebook headings.
- Divide rows and columns with running-stitch dashes; keep illustration inside a hoop or frame.
- Reserve one floss accent — madder, indigo or saffron — for the live element of a view.
- Leave the margin open for timestamps, owners and helper annotations.

### Don't

- Replace structure with atmospheric gradients or pastel background washes.
- Put a single accent edge on a card, or trap navigation in a floating pill bar.
- Let imagery bleed across functional controls.
- Spread all three flosses across the chrome in the same view.
- Round everything into soft blobs that erase the woven, planner-square feel.

### Accessibility

Body 17px+; deep indigo text #1E2A44 on linen clears 4.5:1; floss accents carry linen labels at AA; status never relies on colour alone (a mono label and a dot accompany every floss pill); motion respects prefers-reduced-motion and the settled state renders with no JavaScript.

## Imagery Direction

### Pairs With

woven-sampler-embroidery

### Summary

Subjects rendered as hand-embroidered woven textile — directional satin-stitch fills, couched outlines, french knots, on a visible linen warp-weft weave — in the Madder Skein flosses on a linen ground.

### Subjects

- a flat-lay of stationery and sewing objects worked in thread
- an embroidered botanical hoop
- a stitched sampler band
- a woven map of an order ledger

### Usage

One full-bleed hero per landing; spot illustration bounded inside an embroidery hoop or a framed window, never bleeding across controls.

# Selvage

## Overview

Selvage keeps the discipline of a Japanese stationery planner — ruled columns, edge labels, open margins, bounded illustration — but works every surface in woven linen and embroidery floss. The grid is a real warp-and-weft weave, section labels are stitched fabric tabs that protrude from a panel's edge, dividers are running stitches, and pictures live inside an embroidery hoop. Structure is woven in, never drawn on top; warmth comes from honest material and three muted flosses used like highlighters on a calm linen ground.

### Values

- planner discipline expressed as a real woven warp-and-weft grid
- section labels as stitched selvedge tabs, findable at a glance
- illustration kept bounded inside an embroidery hoop or framed window
- open margins for stitched annotations, timestamps and owners
- one floss accent per view, used like a highlighter on linen

### Anti-Values

- atmospheric gradients or pastel washes replacing structure
- a single accent edge stamped on every card
- imagery bleeding across the controls that run the studio
- all three flosses spread across the chrome at once
- soft blobs that erase the woven, planner-square feel

### Visual Character

- the warp-rule grid: a fine warp-and-weft thread grid runs through the ground and every panel, so the module reads as cloth
- selvedge tabs: section names are full-pill fabric tabs dyed madder, indigo or saffron that protrude from a panel's top edge
- running-stitch rules: rows, columns and panel frames divide on dashed running stitches instead of hard lines
- the embroidery hoop: illustration is always bounded inside a circular hoop or a 16:10 framed window, never bleeding free
- stitched marginalia: timestamps, owners and helper copy tuck into the margin as quiet mono annotations

### Grid

A 12-column desk-page grid on desktop, collapsing to a single column under 760px while preserving margin gutters and the woven warp-weft subdivisions inside modules.

### Whitespace

Generous perimeter margins, moderate inter-panel spacing, small internal padding always padded above titles; the open margin is part of the composition.

### Density

comfortable-to-moderate

### Responsive

Single column under 760px; the warp grid and selvedge tabs persist at every width; tables scroll inside their panel; hoops and framed windows move below primary content rather than disappearing; the hero headline shrinks with clamp() and wraps, never clipping at 390px.

### Breakpoints

- **Sm**: 390px
- **Md**: 760px
- **Lg**: 1000px
- **Xl**: 1700px

- **Full**: `9999px`

### Surfaces

- **Treatment**: woven-textile
- **Card Style**: a piece of cloth: warm linen surface with a woven warp-weft grid fill and an inset running-stitch (dashed) frame, lifted by a soft shadow; no border ring
- **Bg Pattern**: woven-grid

### Borders

- **Default Width**: 0
- **Accent Width**: 0
- **Style**: none
- **Character**: no borders; separation comes from an inset running-stitch (dashed) frame, woven texture, and soft shadow

## Components

### Composition

Compose every region as a piece of cloth on a warp-and-weft grid: generous margins, ruled subdivisions, and selvedge-tab labels protruding from panel edges, leaving the margin open for notes.

### Hierarchy

Hierarchy comes from selvedge tabs, running-stitch subdivisions, a quiet serif, mono numerals, and one floss accent on the live element — not from large scale shifts.

### Density

Moderately dense. Information can be plentiful, but every cluster sits inside a labelled woven panel with visible spacing and stitched micro-labels.

### Signature

The selvedge tab + warp-rule grid: every panel is woven cloth with a stitched fabric tab woven into its edge; dividers and the headline highlighter are running stitches.

## 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-019efddc-be6b-7972-89f9-33558ff1c338/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 Let the woven warp-and-weft grid show through the ground and every panel.
- Do Label sections with stitched selvedge tabs; keep them short like notebook headings.
- Do Divide rows and columns with running-stitch dashes; keep illustration inside a hoop or frame.
- Do Reserve one floss accent — madder, indigo or saffron — for the live element of a view.
- Do Leave the margin open for timestamps, owners and helper annotations.
- Don't Replace structure with atmospheric gradients or pastel background washes.
- Don't Put a single accent edge on a card, or trap navigation in a floating pill bar.
- Don't Let imagery bleed across functional controls.
- Don't Spread all three flosses across the chrome in the same view.
- Don't Round everything into soft blobs that erase the woven, planner-square feel.

### Accessibility

Body 17px+; deep indigo text #1E2A44 on linen clears 4.5:1; floss accents carry linen labels at AA; status never relies on colour alone (a mono label and a dot accompany every floss pill); motion respects prefers-reduced-motion and the settled state renders with no JavaScript.
