**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:** first person plural ("we")
- **Headlines:** a label: a noun phrase, no verb
- **Sentences:** about 16 words on average (about 32 characters in Chinese)
- **Register:** 0.47 on a 0–1 scale — plain and neutral

## 版式 Layout

- **Grid:** 10 columns, 15px gutters, max width 1360px
- **Text block:** columns 6–10 of 10 (flush right)
- **First screen:** 55% of the viewport height
- **Sections:** 8, separated by full-width bands alternating paper and panel
- Below 640px wide the grid collapses to one column; separators and the anchor stay.

**First-screen anchor:** one number taken from the facts; about 90% of the first screen's width, centred at 7% from the left edge, rotated -1.5°.

## 字体 Typography

- **Display**: Permanent Marker 400 · set at 400, as written (sentence case), letter-spacing 0.159em — fallback `"Marker Felt", cursive`
- **Body**: IBM Plex Sans Condensed 400/500/600 — fallback `"Arial Narrow", sans-serif`
- **Mono**: Cousine 400/700 — fallback `"Courier New", Courier, monospace`
- **CJK** (Chinese pages): display Noto Sans SC, body Noto Sans SC

Scale: ratio **1.313** on a 15px base → -2: 8.7px · -1: 11.4px · 0: 15px · 1: 19.7px · 2: 25.9px · 3: 34px · 4: 44.6px · 5: 58.5px · 6: 76.9px · 7: 100.9px

## 配色 Colour — light, hue 40.56°

Computed in OKLCH: paper L 0.932 / C 0.005 at hue 40.56°; accents at chroma 0.153, accent2 166.47° 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 | `#ece7e6` | page background |
| ink | `#403531` | primary text |
| muted | `#72645f` | secondary text |
| accent | `#ce5f34` | the anchor and one kind of mark |
| accent2 | `#0093a1` | sparingly, under a tenth of the page |
| rule | `#bbafab` | lines, borders |
| panel | `#e2d7d3` | secondary background |

Contrast (WCAG):

- ink on paper: **9.67:1** — AAA — any text
- muted on paper: **4.63:1** — AA — body text OK
- ink on panel: **8.41:1** — AAA — any text
- accent on paper: **3.23:1** — large text / UI marks only (≥24px or bold ≥19px)
- accent2 on paper: **3.01:1** — large text / UI marks only (≥24px or bold ≥19px)
- #000000 on accent: **5.31:1** — AA — body text OK
- #000000 on accent2: **5.69:1** — AA — body text OK

## 密度 Density — 0.784

0.784 on the density axis (0 = airiest, 1 = most packed): base 15px, line-height 1.41, spacing unit 5px, section gap 61px, max width 1360px.

## 形状与材质 Shape & surface

- **Radius:** 4px on boxes and inputs
- **Borders:** 3px dashed in the rule colour
- **Shadow:** none (never a soft, blurred shadow)
- **Texture:** a fine dot screen (radial-gradient pattern) at 9.6% opacity

```css
body { background-image: radial-gradient(color-mix(in srgb, var(--ink) 9.6%, transparent) 1px, transparent 1.5px); background-size: 6px 6px; }
```

## 母题 Motif

Half circles, each about 20px, along the page edges, at 43°. Draw them with CSS or inline SVG in the palette colours; no icon fonts, no emoji.

## 动效 Motion

Position (transform: translate) changes over 340ms with `cubic-bezier(0.64, 0.2, 0.63, 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

The footer: inverted: paper-coloured on ink.
