**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 singular ("I")
- **Headlines:** a plain statement
- **Sentences:** about 3 words on average (about 6 characters in Chinese)
- **Register:** 0.47 on a 0–1 scale — plain and neutral

## 版式 Layout

- **Grid:** 8 columns, 5px gutters, max width 1400px
- **Text block:** columns 3–7 of 8 (right of centre)
- **First screen:** 76% of the viewport height
- **Sections:** 3, separated by hairline rules in the rule colour
- Below 640px wide the grid collapses to one column; separators and the anchor stay.

**First-screen anchor:** the motif drawn at full scale; about 69% of the first screen's width, centred at 40% from the left edge, rotated -0.5°.

## 字体 Typography

- **Display**: EB Garamond 400/500 + italic · set at 500, small caps (font-variant-caps: all-small-caps), letter-spacing -0.028em — fallback `Garamond, "Times New Roman", serif`
- **Body**: Young Serif 400 — fallback `Georgia, serif`
- **Mono**: Share Tech Mono 400 — fallback `"Courier New", monospace`
- **CJK** (Chinese pages): display ZCOOL QingKe HuangYou, body Noto Serif SC

Scale: ratio **1.091** on a 14.5px base → -2: 12.2px · -1: 13.3px · 0: 14.5px · 1: 15.8px · 2: 17.3px · 3: 18.8px · 4: 20.5px · 5: 22.4px · 6: 24.5px · 7: 26.7px

## 配色 Colour — dark, hue 101.66°

Computed in OKLCH: paper L 0.173 / C 0.032 at hue 101.66°; accents at chroma 0.115, accent2 151.18° 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 | `#131001` | page background |
| ink | `#cfccb2` | primary text |
| muted | `#7f7e70` | secondary text |
| accent | `#897c15` | the anchor and one kind of mark |
| accent2 | `#4b7db6` | sparingly, under a tenth of the page |
| rule | `#3d3a1f` | lines, borders |
| panel | `#1f1c04` | secondary background |

Contrast (WCAG):

- ink on paper: **11.73:1** — AAA — any text
- muted on paper: **4.65:1** — AA — body text OK
- ink on panel: **10.55:1** — AAA — any text
- accent on paper: **4.5:1** — AA — body text OK
- accent2 on paper: **4.45:1** — large text / UI marks only (≥24px or bold ≥19px)
- #000000 on accent: **4.96:1** — AA — body text OK
- #000000 on accent2: **4.91:1** — AA — body text OK

## 密度 Density — 0.878

0.878 on the density axis (0 = airiest, 1 = most packed): base 14.5px, line-height 1.39, spacing unit 5px, section gap 49px, max width 1400px.

## 形状与材质 Shape & surface

- **Radius:** 0 — square corners everywhere
- **Borders:** 3px dotted in the rule colour
- **Shadow:** none (never a soft, blurred shadow)
- **Texture:** a fine dot screen (radial-gradient pattern) at 10.8% opacity

```css
body { background-image: radial-gradient(color-mix(in srgb, var(--ink) 10.8%, transparent) 1px, transparent 1.5px); background-size: 6px 6px; }
```

## 母题 Motif

Hairline rules, each about 20px, as list and heading markers, at 131°. Draw them with CSS or inline SVG in the palette colours; no icon fonts, no emoji.

## 动效 Motion

Colour (color / background-color) changes over 580ms with `cubic-bezier(0, 1.2, 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 primary call to action: set vertically (writing-mode: vertical-rl).
