Herbier

# Herbier

## Philosophy

A botanical-watercolour interface language: every module is mounted like a pressed specimen, with translucent pigment pooled behind the content on warm ivory paper, named with a small accession code, and ruled like a herbarium plate. Delicate to look at, disciplined underneath. It treats interface modules as painted field notes rather than hard mechanical panels.

### Values

- atmospheric clarity through translucent pigment layering on open ivory paper
- paper-first calm with generous breathing room and quiet space
- observational detail framed like a herbarium annotation plate

### Anti-Values

- pure-white SaaS grounds and cold grey neutrals
- single accent edges, nested cards, and chrome-heavy panels
- perfectly flat geometric sterility with no atmosphere

### Visual Character

- Warm ivory paper fields (#F4EEE2) stay visibly open; content floats inside softly tinted watercolour pools instead of full-bleed hard panels, so the page breathes like untouched paper.
- Every container sits on a translucent watercolour wash pseudo-element with blurred, uneven edges, mimicking wet-on-dry botanical painting; sage, teal and rose blooms recolour on palette swap.
- Section headers pair a Cormorant Garamond serif title with a tiny uppercase IBM Plex Mono accession code and a hairline rule extending into whitespace, so each module reads as a curated catalogue plate.
- Low-opacity pressed-leaf and petal silhouettes clip into card corners to frame content with naturalist depth, never blocking legibility.

- **Full**: 9999px

### Shadows

- **Sm**: 0 6px 18px rgba(74,86,72,0.06)
- **Md**: 0 18px 40px rgba(74,86,72,0.10)
- **Lg**: 0 30px 70px rgba(74,86,72,0.13)

### Spacing

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

### Surfaces

- **Treatment**: watercolour-paper
- **Card Style**: Warm ivory sheets floating over translucent sage, teal and rose washes; soft grain, diffused edge-staining, no border and no accent edge. A blurred radial pigment bloom sits behind each module.
- **Bg Pattern**: fine-paper-grain

### Borders

- **Default Width**: 1px
- **Accent Width**: 0
- **Style**: solid
- **Character**: Borders are a deckled paper guide line (#D9D2C2) used sparingly — like archival pencil, never sharp chrome separators. Cards carry no border; hierarchy comes from wash, space, and type.

### Motion

- **Duration**: 320ms
- **Easing**: cubic-bezier(0.22,1,0.36,1)
- **Philosophy**: Deliberate, paper-calm. Sections rise gently on scroll and washes settle in. The fully settled state is the default and renders with no JavaScript; an inline script gates the hidden start-state behind an html.js class. Respects prefers-reduced-motion.

## Rules

### Composition

Build screens like a botanical field notebook: one dominant specimen study area, one secondary annotation rail on a tinted paper band, and smaller supporting observations in airy bands; let one oversized panel dominate instead of equal card rows.

### Hierarchy

Use high-contrast Cormorant Garamond serif display for specimen names and collections, italic for Latin binomials, then small uppercase mono accession codes and muted body copy for measurements, provenance, and notes.

### Density

Low-to-medium density; modules breathe with wide margins and soft atmospheric section gaps, with selective bursts of detail where study data matters. Body text stays 17px+.

### Signature

Every module sits on a translucent watercolour wash pseudo-element with blurred uneven edges; section headers combine a serif title, a tiny uppercase accession code, and a hairline rule running into whitespace; capsule controls shift from dry paper to lightly saturated pigment on hover; low-opacity pressed-leaf silhouettes clip into corners; sage/teal/rose/ochre map onto semantic roles so the signature recolours on palette swap.

## Layout

### Grid

Desktop 12-column grid with a wide reading gutter and frequent asymmetric spans (a dominant study beside a narrow annotation rail); collapses to 8 columns on tablet and a single flowing column on mobile while preserving generous outer margins.

### Whitespace

Whitespace behaves like untouched paper around a watercolour study: broad margins, clear section breathing room, content clusters separated by soft atmospheric gaps.

### Density

Low-to-medium with intentional quiet; never crowd, never clip; keep 17px+ body legible.

### Responsive

Renders from ~390px mobile to 2560px+ ultra-wide; minmax(0,1fr) columns and min-width:0 children prevent blowout; only the hero spans 100vw, contained width is capped and centred on ultra-wide.

### Breakpoints

- **Mobile**: 390-560px single column, non-essential nav and table columns hidden, hairline plate rules drop
- **Tablet**: 768-1024px reduced spans
- **Desktop**: 1100px+ full 12-column grid
- **Ultrawide**: 1180px max contained width, centred

## Guidance

### Do

- Layer translucency and light tonal variation before introducing heavy contrast.
- Frame information like a curated specimen sheet with a serif title, accession code, and measured notes.
- Keep illustration accents soft, desaturated, and peripheral so content stays primary.
- Let one oversized observation panel dominate instead of arranging equal cards in a row.
- Style every control as a translucent capsule or paper-field element with visible focus states.

### Don't

- Do not use pure-white SaaS grounds or cold grey neutrals; tune neutrals warm to the wash.
- Do not give a card a single accent edge, nest cards, or use heavy black strokes.
- Do not fill every area with texture; preserve quiet paper space.
- Do not treat organic motifs as random decoration detached from the information structure.
- Do not use browser-default form controls, emoji on buttons, or symbol glyphs in copy.

### Accessibility

High-contrast botanical ink (#2C3A32) on warm ivory; 17px+ body; every control has a visible sage focus ring (4px rgba(94,134,105,0.16)); status carries a label and dot, never colour alone; motion respects prefers-reduced-motion and the settled state renders with no JavaScript.

## Imagery Direction

### Pairs With

pigment-wash

### Summary

Botanical specimens rendered as confident translucent watercolour with fine ink linework on bright archival paper — flowering stems, fern fronds, eucalyptus, seed pods — composed full-frame for heroes and clipped as low-opacity silhouettes for framing.

### Subjects

- flowering sage stem
- pressed fern fronds
- eucalyptus sprig
- rose hips and seed pods
- dried flower heads
- pressed-leaf silhouettes

### Usage

One full-bleed watercolour study sheet for the landing hero; low-opacity single-leaf silhouettes clipped into card corners as framing; never the medium itself (no brush, paper, or frame).

# Herbier

## Overview

A botanical-watercolour interface language: every module is mounted like a pressed specimen, with translucent pigment pooled behind the content on warm ivory paper, named with a small accession code, and ruled like a herbarium plate. Delicate to look at, disciplined underneath. It treats interface modules as painted field notes rather than hard mechanical panels.

### Values

- atmospheric clarity through translucent pigment layering on open ivory paper
- paper-first calm with generous breathing room and quiet space
- observational detail framed like a herbarium annotation plate

### Anti-Values

- pure-white SaaS grounds and cold grey neutrals
- single accent edges, nested cards, and chrome-heavy panels
- perfectly flat geometric sterility with no atmosphere

### Visual Character

- Warm ivory paper fields (#F4EEE2) stay visibly open; content floats inside softly tinted watercolour pools instead of full-bleed hard panels, so the page breathes like untouched paper.
- Every container sits on a translucent watercolour wash pseudo-element with blurred, uneven edges, mimicking wet-on-dry botanical painting; sage, teal and rose blooms recolour on palette swap.
- Section headers pair a Cormorant Garamond serif title with a tiny uppercase IBM Plex Mono accession code and a hairline rule extending into whitespace, so each module reads as a curated catalogue plate.
- Low-opacity pressed-leaf and petal silhouettes clip into card corners to frame content with naturalist depth, never blocking legibility.

## 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-019ef6e0-e0f3-7192-a363-c3f2dae853d2/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.
