**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

Use only these facts. Do not invent numbers, reviews, awards or customers; leave gaps visibly empty.
- Name: Causeway — a one-day music festival on Skerrow Island
- Date: Saturday 19 June 2027
- The island is reached on foot over a 1.2 km tidal causeway
- Causeway open for arrivals 09:40–13:10 and for departures 22:15–01:30 (that day's tide times)
- Nobody crosses outside those windows; the harbour boat is for emergencies only
- Capacity: 900 people
- Tickets: £54 adult, £27 for ages 12–17, free under 12; on sale 1 March 2027
- Two stages: the Boathouse (indoors, 220 people) and the Field (outdoors)
- Field line-up: The Lantern Choir, Mara Quist, Seven Herons, Low Orbit Brass
- Boathouse line-up: Ada Fenwick (solo cello), Tomasz & the Weir, Kelp, Ruth Ono Trio
- The last set ends at 21:45 so everyone reaches the causeway in time
- No single-use plastic on the island: bring a cup, or buy an enamel one for £6
- Food from two island kitchens; cash and card
- Organised by the Skerrow Island Trust, a volunteer charity; profits go to repairing the sea wall
- Fourth year of the festival, first held in 2024
- Wear boots: parts of the causeway are wet sand and seaweed

## 配色 Colour — dark, hue 322.43°
Computed in OKLCH: paper L 0.252 / C 0.016 at hue 322.43°; accents at chroma 0.143, accent2 122.94° 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 | `#262027` | page background |
| ink | `#d4c5d5` | primary text |
| muted | `#918792` | secondary text |
| accent | `#a15aab` | the anchor and one kind of mark |
| accent2 | `#9a7400` | sparingly, under a tenth of the page |
| rule | `#554956` | lines, borders |
| panel | `#342a36` | secondary background |
Contrast (WCAG):
- ink on paper: **9.67:1** — AAA — any text
- muted on paper: **4.62:1** — AA — body text OK
- ink on panel: **8.33:1** — AAA — any text
- accent on paper: **3.46:1** — large text / UI marks only (≥24px or bold ≥19px)
- accent2 on paper: **3.7:1** — large text / UI marks only (≥24px or bold ≥19px)
- #ffffff on accent: **4.6:1** — AA — body text OK
- #000000 on accent2: **4.87:1** — AA — body text OK
## 密度 Density — 0.278
0.278 on the density axis (0 = airiest, 1 = most packed): base 17px, line-height 1.57, spacing unit 8px, section gap 130px, max width 1180px.
## 形状与材质 Shape & surface
- **Radius:** 16px on boxes and inputs
- **Borders:** 1px solid in the rule colour
- **Shadow:** none (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
Arrows, each about 32px, along the page edges, at 57°. Draw them with CSS or inline SVG in the palette colours; no icon fonts, no emoji.
## 动效 Motion
Position (transform: translate) changes over 480ms with `cubic-bezier(0.77, 0.8, 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 navigation: set vertically (writing-mode: vertical-rl).
