bloomline
Subjects traced with a single confident hairline ink contour that dissolves into feathered translucent periwinkle, cornflower and seafoam-mint blooms over a near-white field, with tiny gradient dots and small floating arc marks as sparse luminous accents — high-key, milky, airy.
One full-bleed landing hero in the Bloomline technique (a songbird in flight); feature and illustration slots reuse the single-stroke hairline + bloom treatment as inline SVG. Generated with nano-banana-pro (Gemini 3 Pro image).
# Halation ## Philosophy A restrained, luminous interface language: one confident hairline traces a form while colour blooms outward like watercolour mist over a milky cool field. Emphasis is a glow, never a block. It reads airy, editorial, and calm — a gallery wall, not a dense dashboard. ### Values - calm visual pacing - atmosphere over hard decoration - clarity through structural whitespace - gentle luminous warmth - illustration reduced to a single line ### Anti-Values - dense dashboards - heavy skeuomorphism - high-contrast aggression - busy textures - crowded iconography ### Visual Character - blurred radial colour blooms positioned behind hero and section wrappers - translucent white glass panels with backdrop blur floating over the bloom layer - single-stroke hairline SVG micro-illustrations with tiny gradient dots and floating arc marks - emphasis as soft glow underlines and halo pills instead of solid fills - oversized gallery margins and staggered negative space for a slow, calm cadence ## Tokens ### Colors | Name | Value | |------|-------| | bg | `#F6F8FF` | | surface | `rgba(255,255,255,0.74)` | | surface_solid | `#FFFFFF` | | text | `#20283F` | | muted | `#687192` | | border | `rgba(111,124,255,0.16)` | | accent | `#6F7CFF` | | accent_2 | `#8ED8D2` | | accent_soft | `#B8C2FF` | | on_accent | `#FFFFFF` | | success | `#5FB89A` | | warning | `#D8A45F` | | error | `#D96C85` | | info | `#6F7CFF` | ### Typography - **Base Size**: 17px - **Body Font**: Manrope - **Heading Font**: Cormorant Garamond - **Mono Font**: JetBrains Mono - **Heading Weight**: 600 - **Heading Transform**: none - **Letter Spacing**: -0.01em - **Line Height**: 1.62 - **Scale Ratio**: 1.25 - **Google Fonts Url**: https://fonts.googleapis.com/css2?family=Cormorant+Garamond:ital,wght@0,500;0,600;0,700;1,500;1,600&family=JetBrains+Mono:wght@400;500&family=Manrope:wght@400;500;600;700&display=swap ### Radii - **None**: 0 - **Md**: 16px - **Lg**: 24px - **Full**: 9999px ### Shadows - **Sm**: 0 10px 30px rgba(111,124,255,0.08) - **Md**: 0 24px 60px rgba(111,124,255,0.12) - **Lg**: 0 36px 90px rgba(111,124,255,0.16) ### Spacing - **Base**: 8px - **Scale**: [4,8,12,16,24,32,48,64,96,120] ### Surfaces - **Treatment**: glass - **Card Style**: translucent white panels with backdrop blur, floating over pale atmospheric colour blooms - **Bg Pattern**: blurred radial colour blooms ### Borders - **Default Width**: 1px - **Accent Width**: 1px - **Style**: solid - **Character**: barely-there luminous hairlines that define space without hard separation ### Motion - **Duration**: 600ms - **Easing**: cubic-bezier(0.22,1,0.36,1) - **Philosophy**: deliberate; settled state visible with no JS, motion layered on top, respects reduced-motion ## Rules ### Composition Large breathing zones with asymmetric editorial grouping.

# Halation
## Overview
A restrained, luminous interface language: one confident hairline traces a form while colour blooms outward like watercolour mist over a milky cool field. Emphasis is a glow, never a block. It reads airy, editorial, and calm — a gallery wall, not a dense dashboard.
### Values
- calm visual pacing
- atmosphere over hard decoration
- clarity through structural whitespace
- gentle luminous warmth
- illustration reduced to a single line
### Anti-Values
- dense dashboards
- heavy skeuomorphism
- high-contrast aggression
- busy textures
- crowded iconography
### Visual Character
- blurred radial colour blooms positioned behind hero and section wrappers
- translucent white glass panels with backdrop blur floating over the bloom layer
- single-stroke hairline SVG micro-illustrations with tiny gradient dots and floating arc marks
- emphasis as soft glow underlines and halo pills instead of solid fills
- oversized gallery margins and staggered negative space for a slow, calm cadence
## Colors
Use the YAML color tokens as the normative palette. The prose below names the roles agents should preserve when generating UI.
| Token | Value |
|-------|-------|
| bg | `#F6F8FF` |
| surface_solid | `#FFFFFF` |
| text | `#20283F` |
| muted | `#687192` |
| accent | `#6F7CFF` |
| accent_2 | `#8ED8D2` |
| accent_soft | `#B8C2FF` |
| on_accent | `#FFFFFF` |
| success | `#5FB89A` |
| warning | `#D8A45F` |

### Grid
12-column desktop grid; content spans 4-7 columns with empty columns preserved for calm. Tablet collapses to 8 columns; mobile to a single flowing stack with vertical breathing room retained.
### Whitespace
Structural, not residual: 96-120px section padding on desktop, 40-64px on tablet, 24-32px on mobile.
### Density
low
### Responsive
Renders from ~390px mobile to 2560px+ ultra-wide; single column on mobile, capped and centred contained content on ultra-wide, only the full-bleed hero spans 100vw.
### Breakpoints

- **Bg Pattern**: blurred radial colour blooms
### Borders
- **Default Width**: 1px
- **Accent Width**: 1px
- **Style**: solid
- **Character**: barely-there luminous hairlines that define space without hard separation
## Components
### Composition
Large breathing zones with asymmetric editorial grouping. Atmospheric blooms anchor regions while translucent glass panels float lightly within them. Never more than two levels of containment; never nested cards.
### Hierarchy
Lead with elegant Cormorant serif headlines, then quiet Manrope body, then ultra-light JetBrains Mono metadata. Hierarchy comes from spacing, scale, and haze-backed grouping before colour contrast.
### Density
Low. Components feel curated and sparing, with meaningful empty space between modules and controlled line length.
### Signature
The halation bloom: a blurred radial colour wash sits behind content and fades to nothing at its edges; emphasis arrives as glow (soft underline, halo pill) rather than a hard fill, and recolours on palette swap via the accent role vars.
## 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-019efa16-d17d-7320-a992-4f271c14b4c2/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 colour as atmosphere and emphasis as glow
- Do Keep illustrations sparse, single-stroke, diagram-like
- Do Preserve generous gallery margins even when content is short
- Do Prefer feathered blooms and translucent glass over solid fills
- Do Balance Cormorant serif elegance with plain modern Manrope body
- Don't Fill every area with cards or decoration
- Don't Use thick dark borders or hard drop shadows
- Don't Let a saturated colour dominate as a solid field
- Don't Introduce photo-real scenes or detailed illustrations
- Don't Compress spacing to fit more modules above the fold
### Accessibility
Body text 17px+, table rows 14.5px+. Text #20283F on the #F6F8FF ground exceeds 4.5:1. Emphasis never relies on colour alone (glow pairs with weight/shape). Motion respects prefers-reduced-motion; settled state visible with no JS. Form controls fully styled with visible focus rings.
## Imagery Direction
### Pairs With
bloomline
### Summary
Subjects traced with a single confident hairline ink contour that dissolves into feathered translucent periwinkle, cornflower and seafoam-mint blooms over a near-white field, with tiny gradient dots and small floating arc marks as sparse luminous accents — high-key, milky, airy.
### Subjects
- birds and feathers in flight
- botanical forms and stems
- flowing fabric and ribbons
- abstract single-line gestures
### Usage
One full-bleed landing hero in the Bloomline technique (a songbird in flight); feature and illustration slots reuse the single-stroke hairline + bloom treatment as inline SVG. Generated with nano-banana-pro (Gemini 3 Pro image).
### Engine Hints
- **Generator**: nano-banana-pro
- **Model**: gemini-3-pro-image-preview
- **Provider**: gemini
- **Tool**: nano-banana-pro MCP
- **Hero Aspect**: 16:9
- **Image Size**: 2K
- **Note**: OpenAI image generation was billing-capped; hero generated directly via nano-banana-pro.

# Halation shadcn/ui Components
Artifact: `component-recipes-v1`
Author: `katagami-ui-projection`
Language ID: `en-019efa16-d17d-7320-a992-4f271c14b4c2`
Slug: `halation`
## Intent
A restrained, luminous interface language: one confident hairline traces a form while colour blooms outward like watercolour mist over a milky cool field. Emphasis is a glow, never a block. It reads airy, editorial, and calm — a gallery wall, not a dense dashboard.
## 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
- blurred radial colour blooms positioned behind hero and section wrappers
- translucent white glass panels with backdrop blur floating over the bloom layer
- single-stroke hairline SVG micro-illustrations with tiny gradient dots and floating arc marks
- emphasis as soft glow underlines and halo pills instead of solid fills
- oversized gallery margins and staggered negative space for a slow, calm cadence

## 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/halation/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 colour as atmosphere and emphasis as glow; Keep illustrations sparse, single-stroke, diagram-like; Preserve generous gallery margins even when content is short; Prefer feathered blooms and translucent glass over solid fills; Balance Cormorant serif elegance with plain modern Manrope body
- Do not: Fill every area with cards or decoration; Use thick dark borders or hard drop shadows; Let a saturated colour dominate as a solid field; Introduce photo-real scenes or detailed illustrations; Compress spacing to fit more modules above the fold
## Copy-paste component example
This generated starter proves the import shape. Production Katagami agents should replace it with a language-specific product composition.
