# Build brief — an original marketing website in the taste of COCOON
> Reference: https://www.cocoonblanket.com · UIDiscovery: https://uidiscovery.com/sites/cocoon · captured 2026-09-23 at a 1440px desktop viewport (+ 390px iPhone shots) · [full page](https://uidiscovery.com/media/captures/cocoon/full.webp) · [scroll video](https://uidiscovery.com/media/captures/cocoon/preview.mp4)
## 1. Goal
Build an original marketing website for **[the user's brand]** that feels as considered as COCOON — same structure, rhythm and polish, entirely new identity and content.
## 2. Originality rules
- Build an ORIGINAL design for the user's own brand in the same *taste* as COCOON: structure, rhythm, hierarchy, palette mood and type pairing.
- Never reuse COCOON's logo, name, product imagery, illustrations, icons, screenshots or copy. Write new copy for the user's product.
- If the user hasn't said what their product is, ask first (or use clearly marked placeholders like [Brand], [Product], [Audience]).
- Reference screenshots are for looking at, not for embedding or tracing.
## 3. The taste, in short
- COCOON (cocoonblanket.com): Shopping marketing website, light, minimal.
- 9 sections: Hero → Features → Logo cloud → Showcase → Features → Showcase → Footer.
- Spacing: about a screen per idea (median section ≈736px).
- Hero headline: 5 words — short and punchy; keep yours under ~9.
- Type: Marcellus headings over Maison Neue body. Imagery: mostly photography, some abstract 3D / gradient art.
## 4. Page structure (top to bottom)
### 1. Hero — state what the product is and for whom in one glance, and offer the primary action.
- Layout: headline-led stack: eyebrow → H1 → supporting line → actions, with a visual beside or below. About one full screen (900px at 1440), page background; 3 image/graphics; primary + secondary button.
- Slots: Eyebrow / announcement pill (optional); H1 (~5 words, like the reference); Supporting line, 1–2 sentences; Primary + secondary action; Hero visual (see image plan).

## 5. Design system
### Colour
| Role | Hex | Use | Contrast on background |
|---|---|---|---|
| background | `#f0f0f0` | page background | — |
| foreground | `#141414` | body text, headings | 16.2:1 |
| accent | `#141414` | none captured — monochrome. Primary buttons invert (foreground fill, background text); add your brand colour only for small highlights | — |
| surface | `#cacaca` | cards, inputs, alternate bands | text on it 11.2:1 |
| muted | `#898989` | secondary text, borders | 3.1:1 — borders / large text only |
Captured palette: `#f0f0f0` `#141414` `#898989` `#cacaca`. Section bands top→bottom: `#f0f0f0` → `#141414`. Roles are assigned automatically — sanity-check them against the screenshot. Keep the palette's *mood* (light, neutral, desaturated) and proportions; swap the accent for the user's brand colour.
### Tokens
```css
:root {
--background: #f0f0f0;
--foreground: #141414;
--accent: #141414;
--surface: #cacaca;
--muted: #898989;
--font-heading: "Marcellus", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
--radius: 12px; /* calibrate from the screenshot */
}
/* Tailwind v4 — in globals.css after @import "tailwindcss"; */
@theme {
--color-background: var(--background);
--color-foreground: var(--foreground);
--color-accent: var(--accent);
--color-surface: var(--surface);
--color-muted: var(--muted);
--font-heading: var(--font-heading);
--font-sans: var(--font-body);
}
```
### Typography
- Headings: **Marcellus** (Google Fonts) — reference uses Marcellus. Free to use — load it directly.
- Body: **Inter** (Google Fonts) — reference uses Maison Neue. “Maison Neue” is a licensed face — use Inter (or Hanken Grotesk) as the free stand-in, or license the original.
- Scale (starting point, sizes weren't measured — calibrate against the 1440px screenshot): display clamp(2.75rem, 6vw, 5rem), h2 clamp(1.75rem, 3vw, 2.5rem), h3 1.25rem, body 1rem–1.125rem / 1.6, small 0.875rem. Headings: tight tracking (-0.02em), line-height 1.05–1.15.
### Spacing & rhythm
Sections run ≈736px tall at 1440 (median; range 216–900px, captures cap at 1700px) — roughly a screen per idea. Start with 96–120px vertical padding per section on desktop and about two-thirds of that on mobile. The background changes 1 time down the page — use band changes to mark chapters. 8px spacing grid, 1200–1280px max content width, 24px (mobile) / 32–48px (desktop) gutters.
### Shape, depth & theme
Flat surfaces, hairline 1px borders in the muted colour, small radii (4–8px), almost no shadow. Read exact corner radius, border and shadow treatment from the screenshots. Light-first; for a dark mode use a near-black (not #000) background, ~90% white text, lift surfaces with lightness not shadow, re-check the accent.
## 6. Imagery plan
Measured from 8 section screenshots: mostly **photography**, some abstract 3D / gradient art (light, neutral, desaturated, Shopping). Still glance at the linked screenshots to match the exact mood.
### Slot 1 · 1. Hero → photography
- Photography, seen in the capture (people). (measured from the screenshot) Count: a set of ~3 in one consistent style. Aspect: 16:9 full-bleed (or 21:9). Look first: [ref 1](https://uidiscovery.com/media/captures/cocoon/s-01.webp)

Look first: [ref 1](https://uidiscovery.com/media/captures/cocoon/s-03.webp) [ref 2](https://uidiscovery.com/media/captures/cocoon/s-08.webp)
- **Stock** — “abstract gradient 3d”: [Unsplash](https://unsplash.com/s/photos/abstract-gradient-3d?orientation=landscape) · [Pexels](https://www.pexels.com/search/abstract%20gradient%203d/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/abstract%20gradient%203d/?orientation=horizontal)

No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 4 · 5. Showcase → photography
- Photography, seen in the capture (food, baked goods, biscuit). (measured from the screenshot) Count: a set of ~8 in one consistent style. Aspect: 16:10. Look first: [ref 1](https://uidiscovery.com/media/captures/cocoon/s-05.webp)
- **Stock** — “minimal store display close up”: [Unsplash](https://unsplash.com/s/photos/minimal-store-display-close-up?orientation=landscape) · [Pexels](https://www.pexels.com/search/minimal%20store%20display%20close%20up/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/minimal%20store%20display%20close%20up/?orientation=horizontal)
- **Generate** — `Photograph: minimal store display close up. Composition: centred subject with even space around it. Lighting: soft natural daylight, airy and high-key.

No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 5 · 6. Showcase → photography
- Photography, seen in the capture (cord, rope). (measured from the screenshot) Count: a set of ~8 in one consistent style. Aspect: 16:10. Look first: [ref 1](https://uidiscovery.com/media/captures/cocoon/s-06.webp)
- **Stock** — “hands opening package close up”: [Unsplash](https://unsplash.com/s/photos/hands-opening-package-close-up?orientation=landscape) · [Pexels](https://www.pexels.com/search/hands%20opening%20package%20close%20up/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/hands%20opening%20package%20close%20up/?orientation=horizontal)
- **Generate** — `Photograph: hands opening package close up. Composition: centred subject with even space around it. Lighting: soft natural daylight, airy and high-key.

No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- **Logos** — 4. Logo cloud: Never generate or stock-source logos. Use your real customers'/partners' marks with permission (monochrome, equal height), or neutral wordmark placeholders until you have them. Integration icons: each tool's official brand kit (Simple Icons is a quick start; trademarks still apply).
- **No imagery (type-led)** — 7. Features: No imagery needed — type, spacing and colour do the work. If the screenshot shows a background graphic, rebuild it in CSS (gradient, grid, noise) or a short muted video, not a stock photo.
- **Icons** — 9. Footer: Use one open-source icon set at one stroke weight — Lucide, Phosphor or Heroicons (MIT) — tinted with the text or accent token. Social icons: Simple Icons.
### If the screenshots show a different style
Open the refs first and name what you actually see (photo / product UI / illustration / abstract gradient or 3D / type only). If it differs from the guess, switch routes — UI is built in code, type-only needs no image, otherwise:
- **illustration** — generate `Flat vector illustration: product flat lay neutral background, friendly simplified shapes, limited palette of #f0f0f0, #141414, #cacaca plus one soft neutral, plenty of empty background, consistent line weight, neutral, desaturated mood. Aspect ratio 16:9. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“shopping flat illustration” on Unsplash](https://unsplash.com/s/photos/shopping-flat-illustration?orientation=landscape) (same query works on Pexels/Pixabay)
- **Licences:** Unsplash and Pexels images are free for commercial use under their own licences; Pixabay under the Pixabay Content License. Check each image's page before use, credit the photographer when asked (good practice anyway), and skip images showing logos, trademarks, branded products or identifiable people without a release.
- **AI generation:** the prompts work with any image model (GPT Image, Imagen, Flux, Midjourney, Firefly, SDXL…) — check its commercial-use terms. Never put the reference brand's name or “in the style of <brand>” in a prompt.
- **Never** download, trace or re-host the reference's own images, illustrations, product shots or logos.
## 7. Build steps
1. Confirm brand, product, audience and the primary action with the user.
2. Set up the tokens (CSS variables / Tailwind @theme) and load the fonts.
3. Build the sections in order, mobile-first, with each reference screenshot open.
4. Write original copy for every slot — match length and tone, never the words.
5. Source every image via the imagery plan (stock or generated); compress it and record credits.
6. Run the checklist at 390 / 768 / 1440px and fix what fails.
## 8. Acceptance checklist
- [ ] Responsive at 390px, 768px and 1440px — no horizontal scroll, tap targets ≥ 44px on mobile.
- [ ] Colour contrast WCAG AA: 4.5:1 body text, 3:1 large text and UI; visible focus states; full keyboard navigation.
- [ ] Semantic HTML: one <h1>, ordered headings, landmarks (header/nav/main/footer), labelled form fields, alt text on meaningful images.
- [ ] Performance: modern image formats with width/height set, lazy-load below the fold, ≤ 2 font families with font-display: swap, LCP < 2.5s.
- [ ] prefers-reduced-motion respected; animations under ~300ms and never blocking content.
- [ ] Originality: no copied logos, images, illustrations or copy from the reference; every image licensed or generated; credits recorded.
## 9. If you use Next.js + Tailwind
Paste the @theme block into globals.css, load fonts with next/font/google, make each section a server component in components/sections/, use next/image with explicit sizes, and keep client components for interactive bits only (menus, toggles, accordions).
