# Sequence Fresnel Product

## Philosophy

Sequence Fresnel Product is a calm white health-tech interface language where genomic intelligence appears as precise micro-sequence marks, quantized strand previews, and blue-green product states rather than biotech illustration.

### Values

- clinical trust without hospital software stiffness
- pixel DNA as data structure rather than decoration
- fresh blue-green highlights used for state and comprehension
- large white product surfaces with careful hierarchy

### Anti-Values

- literal helix wallpaper or molecule clip art
- generic SaaS dashboards with ornamental color rails
- square-grid or dotted default background textures
- retro game pixel styling

### Visual Character

- White and warm-neutral app surfaces use 1px cool borders, broad radius cards, and very soft directional shadows instead of colored strips or heavy panels.
- Genomic motifs are built from 4px by 4px rounded sequence chips arranged on curved SVG paths and compact inline glyph rows, never as background wallpaper.
- Primary actions and selected states use restrained cyan-to-indigo linear gradients inside pill controls, while secondary surfaces stay quiet and nearly white.
- Information hierarchy pairs large editorial headings with compact mono sequence labels, using left-aligned asymmetric product layouts and generous whitespace.

# Sequence Fresnel Product

## Overview

Sequence Fresnel Product is a calm white health-tech interface language where genomic intelligence appears as precise micro-sequence marks, quantized strand previews, and blue-green product states rather than biotech illustration.

### Values

- clinical trust without hospital software stiffness
- pixel DNA as data structure rather than decoration
- fresh blue-green highlights used for state and comprehension
- large white product surfaces with careful hierarchy

### Anti-Values

- literal helix wallpaper or molecule clip art
- generic SaaS dashboards with ornamental color rails
- square-grid or dotted default background textures
- retro game pixel styling

### Visual Character

- White and warm-neutral app surfaces use 1px cool borders, broad radius cards, and very soft directional shadows instead of colored strips or heavy panels.
- Genomic motifs are built from 4px by 4px rounded sequence chips arranged on curved SVG paths and compact inline glyph rows, never as background wallpaper.
- Primary actions and selected states use restrained cyan-to-indigo linear gradients inside pill controls, while secondary surfaces stay quiet and nearly white.
- Information hierarchy pairs large editorial headings with compact mono sequence labels, using left-aligned asymmetric product layouts and generous whitespace.

## 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-019e4c0d-bf37-7532-a34f-3a31d007d18c/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 Use blue, indigo, teal, and turquoise as meaningful state colors in a limited system.

# Sequence Fresnel Product shadcn/ui Components

Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019e4c0d-bf37-7532-a34f-3a31d007d18c`
Slug: `sequence-fresnel-product`

## Intent

Sequence Fresnel Product is a calm white health-tech interface language where genomic intelligence appears as precise micro-sequence marks, quantized strand previews, and blue-green product states rather than biotech illustration.

## 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`.

## Token cues

Colors:

{
  "accent": "#22C7B8",
  "background": "#F8FAFC",
  "border": "#D8E2EA",
  "error": "#DC2626",
  "info": "#0284C7",
  "muted": "#64748B",
  "primary": "#1D4ED8",
  "secondary": "#0F766E",
  "success": "#059669",
  "surface": "#FFFFFF",
  "text": "#102033",
  "warning": "#D97706"
}

Typography:

{
  "base_size": "16px",
  "body_font": "Inter",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=Instrument+Sans:wght@500;600;700&family=Inter:wght@400;500;600;700&display=swap",
  "heading_font": "Instrument Sans",
  "letter_spacing": "-0.018em",
  "line_height": 1.52,
  "mono_font": "IBM Plex Mono",
  "scale_ratio": 1.22
}

## Visual character to preserve

- White and warm-neutral app surfaces use 1px cool borders, broad radius cards, and very soft directional shadows instead of colored strips or heavy panels.
- Genomic motifs are built from 4px by 4px rounded sequence chips arranged on curved SVG paths and compact inline glyph rows, never as background wallpaper.
- Primary actions and selected states use restrained cyan-to-indigo linear gradients inside pill controls, while secondary surfaces stay quiet and nearly white.
- Information hierarchy pairs large editorial headings with compact mono sequence labels, using left-aligned asymmetric product layouts and generous whitespace.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "pebble",
  "border": "solid",
  "underlay": false,

  "motion": "lift",
  "density": "dense",
  "accents": [
    "primary",
    "accent",
    "secondary",
    "muted"
  ]
}

## Signature component recipes

### Button
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/sequence-fresnel-product/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: Use blue, indigo, teal, and turquoise as meaningful state colors in a limited system.; Represent genomics through modular chips, sequence labels, and precise data pixels inside components.; Keep backgrounds clean white or neutral and let spacing, typography, and complete focus rings carry identity.; Build embodiments as specific health-product workflows with real content and review states.
- Do not: Do not use square-grid backgrounds, dotted default fields, or repeated texture behind the whole page.; Do not use DNA helix wallpaper, molecule decorations, lab textbook diagrams, or biotech clip art.; Do not add colored side rails, card stripes, chipped corners, uneven borders, or rainbow accent sprawl.; Do not make the interface feel like a game skin, generic dashboard template, or hospital admin screen.

## Copy-paste component example

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

  "breakpoints": "mobile 375px, tablet 768px, desktop 1440px with card stacks below 860px",
  "grid": "Responsive 12-column product shell that collapses into stacked cards; hero uses 7/5 split and detail areas use content-width constraints rather than rigid square grids.",
  "whitespace": "Large 48-80px page margins on desktop, 24px tablet gutters, and 16px mobile gutters; dense sequence glyphs are isolated in intentional modules."
