# Splice

## Philosophy

A film-lab review console as a design language. Every contact frame lies on one deep-blue lightboard in shot order; you flag the keepers with colour-coded washi tape, and the colour is the decision — it routes each frame to its print run, its hold pile, or its darkroom note. Reimagined from the Washi Tape Grid brief around the SEQUENCE: a sprocket-holed select rail instead of a planner page, a glowing ink-blue board instead of cream paper.

### Values

- Colour is the decision, made physical — three tapes, three routes, all visible on the board
- Sequence first — frames live in shot order on one rail, never scattered
- Nothing decided into a hidden field — every choice shows on the lightboard
- Luminous depth — surfaces glow up from an ink-blue ground, layered like taped stationery
- Accessible by design — colour always pairs with a status dot and its word
- Industrial calm — a precise console voice, not a craft scrapbook

### Anti-Values

- Cream-paper planner pages and friendly rounded stationery warmth
- A dominant dated daily page with slips clustered around it
- Decision hidden behind a status dropdown instead of shown as tape
- Relying on colour alone to carry meaning
- White or light default grounds; grey-grey neutrals

- **Md**: 0 8px 28px rgba(5,10,24,0.45)
- **Lg**: 0 22px 60px rgba(5,10,24,0.55)

### Spacing

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

### Surfaces

- **Treatment**: glow-lift panels on an ink-blue lightboard
- **Card Style**: Lifted blue panels (#16284A) with an inner top-light and a deep paper shadow; frame cells glow toward #233C6B. No borders — separation is glow, tape and space.
- **Bg Pattern**: faint pin-grid (radial dot at 26px, ~0.10 opacity) — the lightboard's perforation grid

### Borders

- **Default Width**: 0
- **Style**: none
- **Character**: No borders and no one-sided accent edges. A card may carry a torn translucent tape header tab (amber/coral/teal) pinned above it, or two hand-cut square corner tabs — never a single coloured edge or rule-line.

### Motion

- **Duration**: 280ms
- **Easing**: cubic-bezier(0.22,0.68,0,1)
- **Easing Tape**: cubic-bezier(0.34,1.3,0.64,1)
- **Philosophy**: Cells lift on hover; sections rise in on scroll. The settled page is the default with no JS (a .js class gates the hidden start). Respects prefers-reduced-motion.

## Rules

### Composition

Build a film-lab review console, not a component catalog: a horizontal sprocket-holed SELECT RAIL of frames in shot order leads, with a contact-sheet grid, roll exposure meters and a frame queue below. The rail is the compositional spine; the dashboard is a sidebar console.

### Hierarchy

Hierarchy is the rail position, frame scale and tape colour: the lead rail dominates, taped selects pull forward, mono frame-codes and stamps carry metadata. Archivo display leads, Inter body reads, Space Mono stamps date. Never solve hierarchy with more accent colours.

### Density

Comfortable console density with strong spacing contrast: 8px clusters, 16px groups, 24px panel padding, 48px section separation, 96px opening field. Frames sit close on the rail; sections breathe.

### Signature

The select rail — a sprocket filmstrip where a torn translucent tape flag routes each frame (amber select, coral hold, teal note); taped contact cells with two hand-cut square corner tabs; dotted-border Space Mono dated stamps at -1.5deg; status dot always paired with its label; route donut and exposure meters drawn from the three tape colours.

## Layout

### Grid

A horizontal rail leads (grid-auto-flow column, scrolls on overflow); below it a contact-sheet auto-fill grid, a 1.5fr/1fr split for meters + chart, and a frame-queue table. The dashboard is a 232px sidebar + fluid main.

### Whitespace

Generous and measured; strong page-edge padding, sections separated by 96px opening fields, panels by space and glow, never by rules or floating gaps.

### Density

balanced

### Responsive

Tablet keeps the rail and stacks the split to one column; mobile is a single column with a horizontally-scrolling rail and the sidebar collapsed to a top strip; non-essential nav hidden. Nothing overflows horizontally.

### Breakpoints

- **Desktop**: 1440
- **Tablet**: 980
- **Mobile**: 640

## Guidance

### Do

- Lead with the select rail; keep frames in shot order and let tape flags route them.
- Tape a card with a torn translucent header tab or two square corner tabs — never a one-sided edge.
- Reserve amber for selects/primary, coral for holds/attention, teal for notes/secondary; pair every colour with a dot and a word.
- Keep the ground deep ink-blue under a faint pin-grid; let frame cells glow up; use cream as the brightest value.
- Stamp closed passes with a dotted-border Space Mono date at a slight tilt.

### Don't

- Default to cream/white grounds, friendly rounded planner pages, or a dominant dated daily page.
- Add borders, hairline dividers, top rules, or single accent edges.
- Use more than three tape colours in proximity, or rely on colour alone for state.
- Trap navigation in a floating pill bar or nest cards.

### Accessibility

Near-white text on ink-blue and ink text on amber keep AA+ contrast; amber/coral/teal are used as fills behind dark text or as dots beside labels, never as body text; the pin-grid stays below 0.10 opacity; every form control is explicitly styled with a visible amber focus ring; status is always a coloured dot paired with its word.

## Imagery Direction

### Pairs With

tearline

### Summary

Torn translucent washi-tape collage (the Tearline technique) applied to film-lab subjects on a deep ink-blue lightboard: filmstrips, contact frames and rolls reconstructed from overlapping semi-transparent tape bands that glow through, with amber/coral/teal highlighter tape and cream as the brightest value, over a faint pin-grid ground.

### Subjects

- a sprocket filmstrip unspooling on a lightboard
- a roll of film
- taped contact-sheet frames
- a lightbox loupe over negatives
- a reel of tape

### Usage

One full-bleed hero of the taped filmstrip + roll on the glowing blue board, the deep-blue scrim weighted lower-left for copy; smaller taped-frame subjects as feature panes and spot collages.

## 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-019efa18-ef0f-7481-ad4a-bac4ce211f44/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 Lead with the select rail; keep frames in shot order and let tape flags route them.
- Do Tape a card with a torn translucent header tab or two square corner tabs — never a one-sided edge.
- Do Reserve amber for selects/primary, coral for holds/attention, teal for notes/secondary; pair every colour with a dot and a word.
- Do Keep the ground deep ink-blue under a faint pin-grid; let frame cells glow up; use cream as the brightest value.
- Do Stamp closed passes with a dotted-border Space Mono date at a slight tilt.
- Don't Default to cream/white grounds, friendly rounded planner pages, or a dominant dated daily page.
- Don't Add borders, hairline dividers, top rules, or single accent edges.
- Don't Use more than three tape colours in proximity, or rely on colour alone for state.
- Don't Trap navigation in a floating pill bar or nest cards.

### Accessibility

Near-white text on ink-blue and ink text on amber keep AA+ contrast; amber/coral/teal are used as fills behind dark text or as dots beside labels, never as body text; the pin-grid stays below 0.10 opacity; every form control is explicitly styled with a visible amber focus ring; status is always a coloured dot paired with its word.
