**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 156.01°

Computed in OKLCH: paper L 0.954 / C 0.026 at hue 156.01°; accents at chroma 0.17, accent2 100.59° 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 | `#e3f5e9` | page background |
| ink | `#293d30` | primary text |
| muted | `#636f67` | secondary text |
| accent | `#00995a` | the anchor and one kind of mark |
| accent2 | `#478be5` | sparingly, under a tenth of the page |
| rule | `#a7c0af` | lines, borders |
| panel | `#d0e8d8` | secondary background |

Contrast (WCAG):

- ink on paper: **10.25:1** — AAA — any text
- muted on paper: **4.63:1** — AA — body text OK
- ink on panel: **8.99:1** — AAA — any text
- accent on paper: **3.24:1** — large text / UI marks only (≥24px or bold ≥19px)
- accent2 on paper: **3.04:1** — large text / UI marks only (≥24px or bold ≥19px)
- #000000 on accent: **5.7:1** — AA — body text OK
- #000000 on accent2: **6.09:1** — AA — body text OK

## 密度 Density — 0.478

0.478 on the density axis (0 = airiest, 1 = most packed): base 16px, line-height 1.51, spacing unit 7px, section gap 103px, max width 1250px.

## 形状与材质 Shape & surface

- **Radius:** 16px on boxes and inputs
- **Borders:** none; use the separators and space
- **Shadow:** hard offset 2px 2px in ink, no blur (never a soft, blurred shadow)
- **Texture:** fine noise grain over the paper at 8.4% 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='0.084'/%3E%3C/svg%3E"); }
```

## 母题 Motif

Dots, each about 56px, as list and heading markers, at 146°. 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 40ms with `cubic-bezier(0.9, 1.4, 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 main headline: set vertically (writing-mode: vertical-rl).
