# Fanfare

## Philosophy

Fanfare treats the interface like a herald's announcement, not a quiet tool. Every important beat is proclaimed on a bold colour cut-band that slices full-width across a bright paper stage, the way an anime title card flashes a named move across the screen. It keeps the spectacle energy of the original gacha-screen idea and trades its midnight-violet gloss and metallic jewel-frames for a luminous bone-white stage where flat graphic accents read like ink and a brass-bright herald cuts in from the side.

### Values

- Hierarchy proclaimed by a colour cut-band, not by text size alone
- A bright paper stage so flat accents read like fresh poster ink
- State told by which accent strikes: vermilion announces, cobalt charges, lemon completes
- Spectacle delivered as flat graphic energy — speed-streaks and spark blooms, never glossy chrome
- Dense HUD read as proclaimed beats stacked down one bright column

### Anti-Values

- Midnight-violet glassy wash and metallic double-frames with jewel corners
- A dark cinema-stage ground that hides the paper-bright energy
- Grey-bordered boxes and floating pill nav widgets
- The eyebrow-tag + two-button + three-stat SaaS hero
- Muted grayscale that suppresses the announcement

### Visual Character

- Proclamation cut: a bold vermilion banner slices full-width across the stage to announce a section, a lemon spark struck at its leading point
- Strike chips: square-cut status chips with one mitred corner, coloured by state
- Spark meters: flat segmented bars that strike a lemon spark at the fill edge
- Herald cut-in: a flat cel-anime figure breaks past its band under a vermilion key-light rim
- Speed-streak rails: thin radiating cobalt streaks behind a focal beat, drawn as flat ink

## Rules

### Composition

Lead with a herald cut-in on a full-bleed key visual, the headline proclaimed beside it on the open stage. Below, announce each section with a full-width colour cut-band header, then a flat panel of content. Keep the primary action a single struck CTA, never a button pair as default furniture.

### Hierarchy

Hierarchy comes from the cut-band and the strike before pure text size. State is told by which accent strikes: vermilion announces / priority, cobalt charges / info, lemon completes. Supporting data is tiered through strike chips, segmented spark meters and mono cues.

### Density

High density organised as proclaimed beats: one herald focal, a stack of cut-band sections, and strike chips and spark meters within each flat panel. Bright stage space is reserved for the speed-streak energy, not neutral whitespace.

### Signature

The proclamation cut (full-width colour banner announcing a section, lemon spark at the strike point), the strike chip (square-cut chip with one mitred corner), the spark meter (flat segmented bar striking a lemon spark at the fill edge), and the herald cut-in (flat cel figure breaking its band under a vermilion key-light rim).

## Layout

### Grid

A contained max-width stage (1180-1320px) with a full-bleed hero and full-bleed cut-band section headers. Desktop runs multi-column flat-panel grids beneath each cut-band; tablet drops to two columns; mobile stacks to a single proclaimed scroll.

### Whitespace

Theatrical on a bright stage: speed-streak energy and spark room around the herald, tight spacing inside dense data panels, generous padding above every title.

### Density

high

### Responsive

From ~390px to 2560px+. Single column on mobile with a wrapping nav; the full-bleed hero re-anchors so the figure stays legible behind a vertical stage-darkening; cut-band headers wrap; headlines shrink with clamp() and wrap, never clipping the 390px edge.

### Breakpoints

- **Mobile**: 0-619px
- **Tablet**: 620-1039px
- **Desktop**: 1040px+

## Guidance

### Do

- Announce every section with a full-width colour cut-band and a lemon spark at its strike point
- Use vermilion, cobalt and lemon as highlighters to encode announce, charge and complete
- Render status as square-cut strike chips and flat segmented spark meters
- Let a flat cel-anime herald break out of its band under a vermilion key-light rim
- Keep the ground a bright bone-white paper stage so flat accents read like poster ink

### Don't

- Do not use midnight-violet glass, metallic double-frames or jewel corners
- Do not drop onto a dark cinema-stage ground; the stage is bright paper
- Do not box the nav into a pill bar or float chrome as a widget
- Do not open the hero with an eyebrow tag, a button pair, or a three-stat row
- Do not swap a regular serif for an italic serif in the headline; strike a colour cut-band on a word instead

### Accessibility

Body 17px+ on the bright stage with high contrast; never encode meaning in accent colour alone (pair every accent with a chip label or meter text); focus rings strike in vermilion; respect prefers-reduced-motion.

## Imagery Direction

### Pairs With

keylight-cel-anime

### Summary

Bold cel-anime / screen-native digital illustration — flat saturated cels, one dramatic key light, rim-lit silhouettes, radiating speed-streaks and sparkle blooms; the figure cuts in from the side leaving open dark stage for the overlay.

### Subjects

- a triumphant herald-courier at the moment of an announcement
- leaping couriers and runners at a reveal
- festival fanfare crowds under fireworks
- hero objects struck by a single key light

### Usage

Landing hero is a full-bleed cel-anime key visual with the herald cut in from the left and open dark stage on the right for the overlay; cut-in portraits use tight crops with a vermilion key-rim.

## Components

### Composition

Lead with a herald cut-in on a full-bleed key visual, the headline proclaimed beside it on the open stage. Below, announce each section with a full-width colour cut-band header, then a flat panel of content. Keep the primary action a single struck CTA, never a button pair as default furniture.

### Hierarchy

Hierarchy comes from the cut-band and the strike before pure text size. State is told by which accent strikes: vermilion announces / priority, cobalt charges / info, lemon completes. Supporting data is tiered through strike chips, segmented spark meters and mono cues.

### Density

High density organised as proclaimed beats: one herald focal, a stack of cut-band sections, and strike chips and spark meters within each flat panel. Bright stage space is reserved for the speed-streak energy, not neutral whitespace.

### Signature

The proclamation cut (full-width colour banner announcing a section, lemon spark at the strike point), the strike chip (square-cut chip with one mitred corner), the spark meter (flat segmented bar striking a lemon spark at the fill edge), and the herald cut-in (flat cel figure breaking its band under a vermilion key-light rim).

## 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-019efdb9-0b5b-77b3-8043-22e8b1706610/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 Announce every section with a full-width colour cut-band and a lemon spark at its strike point
- Do Use vermilion, cobalt and lemon as highlighters to encode announce, charge and complete
- Do Render status as square-cut strike chips and flat segmented spark meters
- Do Let a flat cel-anime herald break out of its band under a vermilion key-light rim
- Do Keep the ground a bright bone-white paper stage so flat accents read like poster ink
- Don't Do not use midnight-violet glass, metallic double-frames or jewel corners
- Don't Do not drop onto a dark cinema-stage ground; the stage is bright paper
- Don't Do not box the nav into a pill bar or float chrome as a widget
- Don't Do not open the hero with an eyebrow tag, a button pair, or a three-stat row
- Don't Do not swap a regular serif for an italic serif in the headline; strike a colour cut-band on a word instead

### Accessibility

Body 17px+ on the bright stage with high contrast; never encode meaning in accent colour alone (pair every accent with a chip label or meter text); focus rings strike in vermilion; respect prefers-reduced-motion.
