**这份 brief 是冻结的执行规格，不是灵感板。** 每个数值都来自哈希：不要替换字体、颜色、栅格或数值，不要"顺手优化"成你习惯的样子。若与全局禁令冲突，以禁令为准；若 twist 无法照字面执行，取最接近字面的做法，并在 HTML 注释里写明。

## 配色 Colour — light, hue 91.09°

Computed in OKLCH: paper L 0.92 / C 0.019 at hue 91.09°; accents at chroma 0.224, accent2 124.12° 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 | `#e9e4d7` | page background |
| ink | `#3e3825` | primary text |
| muted | `#696458` | secondary text |
| accent | `#987900` | the anchor and one kind of mark |
| accent2 | `#008ea6` | sparingly, under a tenth of the page |
| rule | `#b5ae9a` | lines, borders |
| panel | `#dcd6c2` | secondary background |

Contrast (WCAG):

- ink on paper: **9.21:1** — AAA — any text
- muted on paper: **4.64:1** — AA — body text OK
- ink on panel: **8.04:1** — AAA — any text
- accent on paper: **3.26:1** — large text / UI marks only (≥24px or bold ≥19px)
- accent2 on paper: **3.05:1** — large text / UI marks only (≥24px or bold ≥19px)
- #000000 on accent: **5.07:1** — AA — body text OK
- #000000 on accent2: **5.42:1** — AA — body text OK

## 密度 Density — 0.424

0.424 on the density axis (0 = airiest, 1 = most packed): base 16.5px, line-height 1.52, spacing unit 7px, section gap 110px, max width 1230px.

## 形状与材质 Shape & surface

- **Radius:** 0 — square corners everywhere
- **Borders:** 1px dashed in the rule colour
- **Shadow:** hard offset 6px 6px in ink, no blur (never a soft, blurred shadow)
- **Texture:** fine noise grain over the paper at 5.4% opacity

```css
body { background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='160' height='160'%3E%3Cfilter id='n'%3E%3CfeTurbulence type='fractalNoise' baseFrequency='.9'/%3E%3C/filter%3E%3Crect width='100%25' height='100%25' filter='url(%23n)' opacity='0.054000000000000006'/%3E%3C/svg%3E"); }
```

## 母题 Motif

Parallel stripes, each about 7px, between sections, at 3°. Draw them with CSS or inline SVG in the palette colours; no icon fonts, no emoji.

## 动效 Motion

A wipe (clip-path) changes over 250ms with `cubic-bezier(0.13, 1.2, 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

The section headings: set vertically (writing-mode: vertical-rl).
