summary
Luminous Gouache Field Guide treats a product interface as a working artist-naturalist notebook: bright pigments are disciplined into labeled fields, inked rules, registration layers, and calm reading surfaces rather than scattered decoration. The language is for Katagami experiences that need handmade warmth without losing product authority. It borrows watercolor transparency, opaque gouache corrections, risograph misregistration, botanical stationery spacing, and travel-sketch annotation, then compresses them into repeatable product-system moves: paper-first surfaces, sepia ink structure, limited high-chroma utility colors, and evidence of brush, pigment, and page.
values
Handmade evidence: every expressive moment should read as pigment, paper fiber, ink pooling, or print separation, never as a generic digital gradient.Product discipline: illustration is allowed only when it organizes decisions, previews layers, annotates content, or clarifies workflow.Readable warmth: text sits on warm paper reserves with contrast-checked sepia or near-ink surfaces, not on noisy washes.Limited chroma with purpose: cobalt, vermilion, viridian, lemon, and opera pink appear as art-tool roles, not equal decorative confetti.Editorial pacing: layouts use caption systems, specimen margins, figure labels, and generous gutters instead of bento grids or nested stat cards.Print honesty: offset layers, matte opacity, imperfect borders, and registration marks make the system feel authored and produced.
anti-values
×No generic SaaS gradients, pastel AI blobs, or floating abstract shapes that cannot be explained as pigment or print process.×No overbold tight-tracked hero typography, pill-with-dot biscuits, generic bento icon cards, or nested rounded KPI boxes.×No sterile white surfaces: even quiet areas need paper grain, deckled edge logic, or ink-rule tactility.×No childish clip art: botanical and travel-sketch imagery must be observational, labeled, and integrated with product tasks.

rules
composition
Use a 12-column editorial page with a specimen margin and one dominant working canvas. Begin with a quiet title block, then let product controls orbit a textured preview rather than forming equal bento tiles. Reserve chroma for swatches, layer states, brush previews, and figure callouts. Do not fill empty space with icons; empty paper is part of the language. Align annotation labels to ink rules and coordinate ticks so the handmade elements feel measured.
density
Medium density with generous gutters: the interface should feel like a field guide opened on a studio table, with enough controls for a serious tool but enough paper around each cluster to keep pigment texture legible.
hierarchy
Headings are medium-weight Newsreader with loose editorial line breaks, never huge or ultra-bold. Body copy is Atkinson Hyperlegible on warm paper rectangles. Mono labels are small, uppercase, and letter-spaced only enough to resemble specimen captions. Primary actions use filled cobalt or sepia ink blocks with paper-grain texture; secondary actions are underlined ink labels, not pills.
signature patterns
Deckled paper panels: every main surface has a sepia ink border plus an irregular torn-edge pseudo-element created with repeating radial gradients.Watercolor reserve blocks: content sits on solid warm paper while translucent wash slabs extend 12-24px beyond one edge as color-coded context.Riso offset previews: important visual modules duplicate selected shapes with multiply-blended cobalt/vermilion/viridian layers shifted by 3-8px.Specimen-margin annotation: navigation and metadata become thin botanical stems, figure numbers, and coordinate labels placed in a fixed editorial margin.Gouache correction tabs: opaque rectangular swatches overlap corners of panels to show active state, layer status, or saved decisions.

guidance
do
  • Place text on solid warm paper reserves before adding any wash texture behind it.
  • Use cobalt for primary progress, vermilion for decisive marks, viridian for botanical confirmation, lemon for warning highlights, and opera pink only for rare registration or focus annotations.
  • Make illustration functional: layer previews, brush samples, botanical specimen framing, or travel coordinates must relate to the product task.
  • Keep border radii restrained to square joins, 16px working panels, 24px rare canvas sheets, and full radius only for tiny color wells.
  • Use sepia ink captions, figure numbers, and coordinate ticks to establish hierarchy without generic icon cards.
  • Let paper grain and pigment opacity carry atmosphere instead of adding shadows, gradients, or decorative grid filler.
  • Check contrast on every text surface; if a wash reduces clarity, add a paper reserve or move the wash to the edge.
avoid
  • Do not use huge overbold tight headings, gradient keyword emphasis, or glossy hero blobs.
  • Do not arrange content as generic bento cards or nested rounded stat cards.
  • Do not use pill-with-dot status biscuits; use ink captions, swatch tabs, or small ruled labels instead.
  • Do not scatter childish flower icons; botanical references must look observational and integrated.
  • Do not place body text directly over saturated watercolor texture.
  • Do not introduce colors outside the art-tool palette unless they are semantic accessibility states.
  • Do not make surfaces sterile white or textureless; the page must read as paper, pigment, ink, gouache, or riso separation.

# Luminous Gouache Field Guide

## Philosophy

Luminous Gouache Field Guide treats a product interface as a working artist-naturalist notebook: bright pigments are disciplined into labeled fields, inked rules, registration layers, and calm reading surfaces rather than scattered decoration. The language is for Katagami experiences that need handmade warmth without losing product authority. It borrows watercolor transparency, opaque gouache corrections, risograph misregistration, botanical stationery spacing, and travel-sketch annotation, then compresses them into repeatable product-system moves: paper-first surfaces, sepia ink structure, limited high-chroma utility colors, and evidence of brush, pigment, and page.

### Values

- Handmade evidence: every expressive moment should read as pigment, paper fiber, ink pooling, or print separation, never as a generic digital gradient.
- Product discipline: illustration is allowed only when it organizes decisions, previews layers, annotates content, or clarifies workflow.
- Readable warmth: text sits on warm paper reserves with contrast-checked sepia or near-ink surfaces, not on noisy washes.
- Limited chroma with purpose: cobalt, vermilion, viridian, lemon, and opera pink appear as art-tool roles, not equal decorative confetti.
- Editorial pacing: layouts use caption systems, specimen margins, figure labels, and generous gutters instead of bento grids or nested stat cards.
- Print honesty: offset layers, matte opacity, imperfect borders, and registration marks make the system feel authored and produced.

### Anti-Values

- No generic SaaS gradients, pastel AI blobs, or floating abstract shapes that cannot be explained as pigment or print process.
- No overbold tight-tracked hero typography, pill-with-dot biscuits, generic bento icon cards, or nested rounded KPI boxes.
- No sterile white surfaces: even quiet areas need paper grain, deckled edge logic, or ink-rule tactility.
- No childish clip art: botanical and travel-sketch imagery must be observational, labeled, and integrated with product tasks.

### Visual Character

- Warm paper background built from layered radial-gradient fiber noise plus low-opacity linear wash stains, with all text blocks reserving solid paper rectangles for contrast.
- Sepia ink structure uses 1.5px hand-rule borders, square section joins, caption ticks, and occasional deckled border-image simulation instead of soft SaaS outlines.
- High-chroma colors appear as translucent watercolor wash panels with opaque gouache swatch tabs clipped behind content, never as full-page gradients or keyword highlights.
- Riso separation is expressed through duplicate offset silhouettes, CMYK-like registration crosses, and multiply-blended color plates aligned to product preview panels.
- Botanical/travel-sketch margins use thin specimen stems, handwritten-style figure labels, and map-coordinate annotations to frame product workflows without becoming icons.

## Rules

### Composition

Use a 12-column editorial page with a specimen margin and one dominant working canvas. Begin with a quiet title block, then let product controls orbit a textured preview rather than forming equal bento tiles. Reserve chroma for swatches, layer states, brush previews, and figure callouts. Do not fill empty space with icons; empty paper is part of the language. Align annotation labels to ink rules and coordinate ticks so the handmade elements feel measured.

### Density

Medium density with generous gutters: the interface should feel like a field guide opened on a studio table, with enough controls for a serious tool but enough paper around each cluster to keep pigment texture legible.

### Hierarchy

Headings are medium-weight Newsreader with loose editorial line breaks, never huge or ultra-bold. Body copy is Atkinson Hyperlegible on warm paper rectangles. Mono labels are small, uppercase, and letter-spaced only enough to resemble specimen captions. Primary actions use filled cobalt or sepia ink blocks with paper-grain texture; secondary actions are underlined ink labels, not pills.

### Signature Patterns

- Deckled paper panels: every main surface has a sepia ink border plus an irregular torn-edge pseudo-element created with repeating radial gradients.
- Watercolor reserve blocks: content sits on solid warm paper while translucent wash slabs extend 12-24px beyond one edge as color-coded context.
- Riso offset previews: important visual modules duplicate selected shapes with multiply-blended cobalt/vermilion/viridian layers shifted by 3-8px.
- Specimen-margin annotation: navigation and metadata become thin botanical stems, figure numbers, and coordinate labels placed in a fixed editorial margin.
- Gouache correction tabs: opaque rectangular swatches overlap corners of panels to show active state, layer status, or saved decisions.

## Layout

### Breakpoints

- **Desktop**: 1024px+ full field-guide spread
- **Mobile**: 0-639px single-column with margin annotations inline
- **Tablet**: 640-1023px two-column canvas plus notes

### Density

Medium editorial density: information is grouped into named figure zones and product controls, avoiding sparse marketing theatrics and overcrowded dashboards.

### Grid

Desktop uses a 12-column grid with 32px gutters and max-width 1240px; columns 1-2 form a specimen margin, 3-8 hold the product canvas, and 9-12 hold decisions and notes.

### Whitespace

Whitespace behaves like unpainted paper reserves: 24-48px around figure groups, 12-16px inside controls, and wider breathing room where wash texture needs to be visible.

## Guidance

### Do

- Place text on solid warm paper reserves before adding any wash texture behind it.
- Use cobalt for primary progress, vermilion for decisive marks, viridian for botanical confirmation, lemon for warning highlights, and opera pink only for rare registration or focus annotations.
- Make illustration functional: layer previews, brush samples, botanical specimen framing, or travel coordinates must relate to the product task.
- Keep border radii restrained to square joins, 16px working panels, 24px rare canvas sheets, and full radius only for tiny color wells.
- Use sepia ink captions, figure numbers, and coordinate ticks to establish hierarchy without generic icon cards.
- Let paper grain and pigment opacity carry atmosphere instead of adding shadows, gradients, or decorative grid filler.
- Check contrast on every text surface; if a wash reduces clarity, add a paper reserve or move the wash to the edge.

### Don't

- Do not use huge overbold tight headings, gradient keyword emphasis, or glossy hero blobs.
- Do not arrange content as generic bento cards or nested rounded stat cards.
- Do not use pill-with-dot status biscuits; use ink captions, swatch tabs, or small ruled labels instead.
- Do not scatter childish flower icons; botanical references must look observational and integrated.
- Do not place body text directly over saturated watercolor texture.
- Do not introduce colors outside the art-tool palette unless they are semantic accessibility states.
- Do not make surfaces sterile white or textureless; the page must read as paper, pigment, ink, gouache, or riso separation.

### Accessibility

Primary text #2B1A12 on #FFF6DC or #F7EACB exceeds WCAG AA; colored washes stay below text or behind large non-text shapes; focus states use 3px cobalt/sepia offset outlines plus opera registration marks.

### Usage Context

Best for creative product systems, print/layer tools, editorial planning, stationery commerce, botanical archives, and travel-sketch inspired knowledge products that need vivid warmth with clear governance.

# Luminous Gouache Field Guide

## Overview

Luminous Gouache Field Guide treats a product interface as a working artist-naturalist notebook: bright pigments are disciplined into labeled fields, inked rules, registration layers, and calm reading surfaces rather than scattered decoration. The language is for Katagami experiences that need handmade warmth without losing product authority. It borrows watercolor transparency, opaque gouache corrections, risograph misregistration, botanical stationery spacing, and travel-sketch annotation, then compresses them into repeatable product-system moves: paper-first surfaces, sepia ink structure, limited high-chroma utility colors, and evidence of brush, pigment, and page.

### Values

- Handmade evidence: every expressive moment should read as pigment, paper fiber, ink pooling, or print separation, never as a generic digital gradient.
- Product discipline: illustration is allowed only when it organizes decisions, previews layers, annotates content, or clarifies workflow.
- Readable warmth: text sits on warm paper reserves with contrast-checked sepia or near-ink surfaces, not on noisy washes.
- Limited chroma with purpose: cobalt, vermilion, viridian, lemon, and opera pink appear as art-tool roles, not equal decorative confetti.
- Editorial pacing: layouts use caption systems, specimen margins, figure labels, and generous gutters instead of bento grids or nested stat cards.
- Print honesty: offset layers, matte opacity, imperfect borders, and registration marks make the system feel authored and produced.

### Anti-Values

- No generic SaaS gradients, pastel AI blobs, or floating abstract shapes that cannot be explained as pigment or print process.
- No overbold tight-tracked hero typography, pill-with-dot biscuits, generic bento icon cards, or nested rounded KPI boxes.
- No sterile white surfaces: even quiet areas need paper grain, deckled edge logic, or ink-rule tactility.
- No childish clip art: botanical and travel-sketch imagery must be observational, labeled, and integrated with product tasks.

### Visual Character

- Warm paper background built from layered radial-gradient fiber noise plus low-opacity linear wash stains, with all text blocks reserving solid paper rectangles for contrast.
- Sepia ink structure uses 1.5px hand-rule borders, square section joins, caption ticks, and occasional deckled border-image simulation instead of soft SaaS outlines.
- High-chroma colors appear as translucent watercolor wash panels with opaque gouache swatch tabs clipped behind content, never as full-page gradients or keyword highlights.
- Riso separation is expressed through duplicate offset silhouettes, CMYK-like registration crosses, and multiply-blended color plates aligned to product preview panels.
- Botanical/travel-sketch margins use thin specimen stems, handwritten-style figure labels, and map-coordinate annotations to frame product workflows without becoming icons.

- Gouache correction tabs: opaque rectangular swatches overlap corners of panels to show active state, layer status, or saved decisions.

## 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/luminous-gouache-field-guide/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 Place text on solid warm paper reserves before adding any wash texture behind it.
- Do Use cobalt for primary progress, vermilion for decisive marks, viridian for botanical confirmation, lemon for warning highlights, and opera pink only for rare registration or focus annotations.
- Do Make illustration functional: layer previews, brush samples, botanical specimen framing, or travel coordinates must relate to the product task.
- Do Keep border radii restrained to square joins, 16px working panels, 24px rare canvas sheets, and full radius only for tiny color wells.
- Do Use sepia ink captions, figure numbers, and coordinate ticks to establish hierarchy without generic icon cards.
- Do Let paper grain and pigment opacity carry atmosphere instead of adding shadows, gradients, or decorative grid filler.
- Do Check contrast on every text surface; if a wash reduces clarity, add a paper reserve or move the wash to the edge.
- Don't Do not use huge overbold tight headings, gradient keyword emphasis, or glossy hero blobs.
- Don't Do not arrange content as generic bento cards or nested rounded stat cards.
- Don't Do not use pill-with-dot status biscuits; use ink captions, swatch tabs, or small ruled labels instead.
- Don't Do not scatter childish flower icons; botanical references must look observational and integrated.
- Don't Do not place body text directly over saturated watercolor texture.
- Don't Do not introduce colors outside the art-tool palette unless they are semantic accessibility states.
- Don't Do not make surfaces sterile white or textureless; the page must read as paper, pigment, ink, gouache, or riso separation.

### Accessibility

Primary text #2B1A12 on #FFF6DC or #F7EACB exceeds WCAG AA; colored washes stay below text or behind large non-text shapes; focus states use 3px cobalt/sepia offset outlines plus opera registration marks.

### Usage Context

Best for creative product systems, print/layer tools, editorial planning, stationery commerce, botanical archives, and travel-sketch inspired knowledge products that need vivid warmth with clear governance.

# Luminous Gouache Field Guide shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `luminous-gouache-field-guide`
Slug: `luminous-gouache-field-guide`

## Intent

Luminous Gouache Field Guide treats a product interface as a working artist-naturalist notebook: bright pigments are disciplined into labeled fields, inked rules, registration layers, and calm reading surfaces rather than scattered decoration. The language is for Katagami experiences that need handmade warmth without losing product authority. It borrows watercolor transparency, opaque gouache corrections, risograph misregistration, botanical stationery spacing, and travel-sketch annotation, then compresses them into repeatable product-system moves: paper-first surfaces, sepia ink structure, limited high-chroma utility colors, and evidence of brush, pigment, and page.

## Required primitives

- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Install with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

## Visual character to preserve

- Warm paper background built from layered radial-gradient fiber noise plus low-opacity linear wash stains, with all text blocks reserving solid paper rectangles for contrast.
- Sepia ink structure uses 1.5px hand-rule borders, square section joins, caption ticks, and occasional deckled border-image simulation instead of soft SaaS outlines.
- High-chroma colors appear as translucent watercolor wash panels with opaque gouache swatch tabs clipped behind content, never as full-page gradients or keyword highlights.
- Riso separation is expressed through duplicate offset silhouettes, CMYK-like registration crosses, and multiply-blended color plates aligned to product preview panels.
- Botanical/travel-sketch margins use thin specimen stems, handwritten-style figure labels, and map-coordinate annotations to frame product workflows without becoming icons.

Use `Button` for primary, secondary, outline, and ghost actions. Primary actions must expose the language's strongest contrast pair, while secondary and ghost actions should preserve the surface treatment instead of falling back to default neutral SaaS styling.

### Card
Use `Card`, `CardHeader`, `CardContent`, `CardFooter`, and `CardAction` as the main composition frame. Cards should demonstrate the language's surface, border, hierarchy, and density rules rather than appearing as generic rounded rectangles.

### Input and Textarea
Use `Input` and `Textarea` with visible focus rings, field labels, validation states, and the language's rhythm. Forms should show real product content, not placeholder-only controls.

### Select, Tabs, and Table
Use `Select`, `Tabs`, and `Table` to prove navigation, filtering, and dense data states. The table should show row rhythm, separators, hover/focus states, and an empty or status state when the language calls for it.

### Dialog and Sheet
Use `Dialog` for centered decisions and `Sheet` for contextual editing. Both should inherit the language's spacing, border, overlay, and motion rules.

## Preview shots

- `application-shell`: dashboard or workspace shell with navigation, cards, forms, and state badges.
- `detail-editor`: focused editing flow using input, textarea, select, switch/checkbox, dialog or sheet, and action buttons.
- `data-operations`: table-heavy operational view with tabs, dropdown menu affordances, badges, and destructive/empty states.
- Each preview shot must include a renderable `scene` payload with concrete headline, description, actions, and rows/fields/stats for the UI preview.

## Implementation contract

- Start from local `ui/src/components/ui` shadcn-style primitives; do not create a second component system.
- Apply `/katagami/shadcn/luminous-gouache-field-guide/registry-theme.json` variables, then use these recipes for composition and state design.
- Preserve Katagami token names as source metadata; shadcn semantic names are only the export surface.
- Do: Place text on solid warm paper reserves before adding any wash texture behind it.; Use cobalt for primary progress, vermilion for decisive marks, viridian for botanical confirmation, lemon for warning highlights, and opera pink only for rare registration or focus annotations.; Make illustration functional: layer previews, brush samples, botanical specimen framing, or travel coordinates must relate to the product task.; Keep border radii restrained to square joins, 16px working panels, 24px rare canvas sheets, and full radius only for tiny color wells.; Use sepia ink captions, figure numbers, and coordinate ticks to establish hierarchy without generic icon cards.; Let paper grain and pigment opacity carry atmosphere instead of adding shadows, gradients, or decorative grid filler.; Check contrast on every text surface; if a wash reduces clarity, add a paper reserve or move the wash to the edge.
- Do not: Do not use huge overbold tight headings, gradient keyword emphasis, or glossy hero blobs.; Do not arrange content as generic bento cards or nested rounded stat cards.; Do not use pill-with-dot status biscuits; use ink captions, swatch tabs, or small ruled labels instead.; Do not scatter childish flower icons; botanical references must look observational and integrated.; Do not place body text directly over saturated watercolor texture.; Do not introduce colors outside the art-tool palette unless they are semantic accessibility states.; Do not make surfaces sterile white or textureless; the page must read as paper, pigment, ink, gouache, or riso separation.

## Copy-paste component example

This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
