**This brief is a frozen spec, not a mood board.** Every value comes from the hash: do not swap fonts, colours, the grid or the numbers for ones you prefer. Global bans override everything; if the twist cannot apply literally, apply the nearest literal reading and say so in an HTML comment.

## 内容 Content

**Subject:** Sluice — self-hosted webhook inbox

Use only these facts. Do not invent numbers, reviews, awards or customers; leave gaps visibly empty.

- Name: Sluice — a self-hosted inbox for webhooks
- What it does: gives you a public URL for webhooks, stores every delivery, and forwards it to your local or internal service
- One static binary, about 11 MB, for Linux, macOS and Windows on amd64 and arm64
- Storage: a single SQLite file; no Redis, no Postgres, no queue to run
- Install: curl -fsSL https://sluice.example/install.sh | sh
- Start: sluice serve --forward http://localhost:3000
- Retries failed forwards with exponential backoff for up to 72 hours
- Replay any stored delivery: sluice replay <delivery-id>
- Verifies HMAC-SHA256 signatures and rejects deliveries older than 5 minutes
- Web UI on port 8081: search deliveries by path, header or body text
- Keeps deliveries for 30 days by default; change it with --retain
- 1,800 deliveries per second on a 2-vCPU VM, in the project's own benchmark
- No hosted service, no account, no telemetry
- Written in Go; MIT licence; 41 contributors
- Current version 0.9.2, released 14 October 2026
- Maintainer: Ines Okafor, who started it in 2023 after losing a weekend of payment webhooks

## 文案语气 Voice

- **Person:** second person ("you")
- **Headlines:** a label: a noun phrase, no verb
- **Sentences:** about 5 words on average (about 10 characters in Chinese)
- **Register:** 0.33 on a 0–1 scale — spoken and casual

## 版式 Layout

- **Grid:** 9 columns, 5px gutters, max width 1370px
- **Text block:** columns 2–9 of 9 (flush right)
- **First screen:** 99% of the viewport height
- **Sections:** 7, separated by space only: the section gap, no lines or fills
- Below 640px wide the grid collapses to one column; separators and the anchor stay.

**First-screen anchor:** the motif drawn at full scale; about 98% of the first screen's width, centred at 87% from the left edge, rotated -8°.

## 字体 Typography

- **Display**: Cormorant SC 500/600 · set at 600, UPPERCASE, letter-spacing 0.191em — fallback `Garamond, Georgia, serif`
- **Body**: Overpass 400/600 — fallback `Arial, sans-serif`
- **Mono**: Overpass Mono 400/600 — fallback `"Courier New", monospace`

## 配色 Colour — light, hue 156.61°

Computed in OKLCH: paper L 0.968 / C 0.018 at hue 156.61°; accents at chroma 0.153, accent2 35.88° round the wheel. Text lightness is solved for contrast (ink ≥ 7.5:1, muted ≥ 4.6:1, accents ≥ 3:1 on paper).

| token | hex | role |
|---|---|---|
| paper | `#ebf8f0` | page background |
| ink | `#2b3d32` | primary text |
| muted | `#647169` | secondary text |
| accent | `#009c5d` | the anchor and one kind of mark |
| accent2 | `#009d9a` | sparingly, under a tenth of the page |
| rule | `#afc3b6` | lines, borders |
| panel | `#d8ebdf` | secondary background |

Contrast (WCAG):

- ink on paper: **10.58:1** — AAA — any text
- muted on paper: **4.68:1** — AA — body text OK
- ink on panel: **9.29:1** — AAA — any text
- accent on paper: **3.25:1** — large text / UI marks only (≥24px or bold ≥19px)
- accent2 on paper: **3.06:1** — large text / UI marks only (≥24px or bold ≥19px)
- #000000 on accent: **5.91:1** — AA — body text OK
- #000000 on accent2: **6.29:1** — AA — body text OK

## 密度 Density — 0.792

0.792 on the density axis (0 = airiest, 1 = most packed): base 15px, line-height 1.41, spacing unit 5px, section gap 60px, max width 1370px.

## 形状与材质 Shape & surface

- **Radius:** 8px on boxes and inputs
- **Borders:** none; use the separators and space
- **Shadow:** hard offset 6px 6px in ink, no blur (never a soft, blurred shadow)
- **Texture:** flat colour, no texture

## 母题 Motif

Small crosses (+), each about 15px, along the page edges, at 126°. Draw them with CSS or inline SVG in the palette colours; no icon fonts, no emoji.

## 动效 Motion

Opacity changes over 390ms with `cubic-bezier(0.77, 0.2, 0.37, 1)`, on hover, focus and state changes, plus the anchor once on load. Never animate every section on scroll. Under prefers-reduced-motion nothing moves.

## 变数 Twist

Set the footer at 0.34× the size it would normally get.
