## Token cues

Colors:

{
  "accent": "#e8a830",
  "background": "#f8f6f0",
  "border": "rgba(42,37,32,0.12)",
  "error": "#c84040",

}

Typography:

{
  "base_size": "15px",
  "font_body": "Source Sans 3, system-ui, sans-serif",
  "font_heading": "Crimson Pro, Georgia, serif",
  "font_mono": "Fira Code, Consolas, monospace",
  "google_fonts_url": "https://fonts.googleapis.com/css2?family=Crimson+Pro:wght@400;500;600;700&family=Source+Sans+3:wght@400;500;600;700&family=Fira+Code:wght@400;500;600&display=swap",

    "light": 300,
    "medium": 500,
    "regular": 400,
    "semibold": 600
  }
}

## Visual character to preserve

- Tomoe River paper spread with a visible center gutter, cream #fdfcf8 surfaces, 1px rgba(42,37,32,0.12) rules, and radial-gradient dot grid every 20px.
- Hand-kept planner artifacts: rotated monospace date stamps, dotted sticker badges, edge page tabs using clip-path, and margin notes connected by thin guide lines.
- Analog emphasis instead of digital chrome: translucent highlighter spans in yellow or pink, wavy pen-stroke underlines, square 2-4px corners, and almost-flat shadows.

## ShadSync visual profile

{
  "family": "paper-collage",
  "material": "paper",
  "contour": "default",
  "border": "dashed",
  "underlay": false,
  "grain": true,
  "stickerBadges": true,
  "motion": "lift-rotate",
  "density": "balanced",
  "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/techo-page/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 dot grid background on every page surface — it is the foundational visual identity; Apply highlighter-style backgrounds for emphasis using semi-transparent yellow or pink with slight padding overshoot; Use date stamps in monospace with bordered rectangles and slight rotation for temporal markers; Maintain the two-page spread metaphor on desktop with a visible center gutter; Use Crimson Pro for all headings to evoke formal handwritten notes; Keep borders light and subtle — paper sections are defined by whitespace and thin rules, not heavy boxes; Apply pen-stroke style underlines using SVG wavy paths for decorative emphasis; Use sticker-like badges with dotted borders and 1-2 degree rotation for status indicators and tags; Place margin annotations in lighter color offset to the side, connected by thin guide lines; Maintain generous whitespace — the page must breathe like a real planner with room to write
- Do not: Never use heavy drop shadows — planners sit flat on a desk, not floating in space; Never use perfectly straight mechanical underlines — they break the analog illusion; Avoid large border-radius values — paper corners are nearly square (max 4px); Do not use bright saturated backgrounds for containers — surfaces should be paper-white or cream; Avoid centered text layouts — planners are left-aligned with structured margins; Never use gradient backgrounds — paper is flat, not dimensional; Do not overcrowd the page — if it would not fit on a real A5 planner spread, it is too dense; Avoid generic sans-serif buttons — interactive elements should feel like they belong on the page (stamps, checkboxes, tabs); Never use animations longer than 500ms — analog tools respond immediately; Do not use neon or electric colors — the palette is fountain pen inks, markers, and pencil graphite

## Copy-paste component example

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