## 1. Goal
Build an original marketing website for **[the user's brand]** that feels as considered as Polar — 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 Polar: structure, rhythm, hierarchy, palette mood and type pairing.
- Never reuse Polar'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
- Polar (polar.sh): Finance marketing website, light.
- 8 sections: Hero → Features → Content → Features → Content → Features.
- Spacing: long, content-rich sections (median ≈1160px tall at 1440).
- Hero headline: 2 words — short and punchy; keep yours under ~9.
- Type: one family (PP Neue Montreal). Imagery: mostly abstract 3D / gradient art, some product UI screenshots/mockups.
## 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 (1108px at 1440), own dark band #090909; 1 image/graphic; one primary button.
- Slots: Eyebrow / announcement pill (optional); H1 (~3 words, like the reference); Supporting line, 1–2 sentences; One primary action; Hero visual (see image plan).
- Topic (tone/length only — never reuse): “Meet Polar”
- [Screenshot](https://uidiscovery.com/media/captures/polar/s-01.webp) · imagery: slot 1
### 2. Features — explain the key benefits, grouped so each can be scanned in seconds.
- Layout: section title over a grid or alternating rows of benefit items. About one full screen (1088px at 1440), own dark band #090909; no images (type-led); no interactive controls; 6 headings → ~5 items under a title.
- Slots: Section title (~3 words, like the reference); 5 items: icon or visual + short title + 1–2 line description.
- Topic (tone/length only — never reuse): “Platform”

## 5. Design system
### Colour
| Role | Hex | Use | Contrast on background |
|---|---|---|---|
| background | `#ffffff` | page background | — |
| foreground | `#000000` | body text, headings | 21.0:1 |
| accent | `#433a14` | primary buttons, links, highlights — sparingly | 11.3:1 |
| surface | `#ffffff` | cards, inputs, alternate bands | text on it 21.0:1 |
| muted | `#858585` | secondary text, borders | 3.7:1 — borders / large text only |
Captured palette: `#ffffff` `#858585` `#212121` `#000000` `#433a14`. Roles are assigned automatically — sanity-check them against the screenshot. Keep the palette's *mood* (light, warm) and proportions; swap the accent for the user's brand colour.
### Tokens
```css
:root {
--background: #ffffff;
--foreground: #000000;
--accent: #433a14;
--surface: #ffffff;
--muted: #858585;
--font-heading: "Hanken Grotesk", ui-sans-serif, system-ui, sans-serif;
--font-body: "Hanken Grotesk", 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: **Hanken Grotesk** (Google Fonts) — reference uses PP Neue Montreal. “PP Neue Montreal” is a licensed face — use Hanken Grotesk (or Inter) as the free stand-in, or license the original.
- Body: same family — a single-family system; create contrast with size and weight, not a second face.
- 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 ≈1160px tall at 1440 (median; range 1078–1700px, captures cap at 1700px) — long, content-rich chapters. Start with 96–128px vertical padding per section on desktop and about two-thirds of that on mobile. One continuous background — separate sections with space and type, not colour bands. 8px spacing grid, 1200–1280px max content width, 24px (mobile) / 32–48px (desktop) gutters.
### Shape, depth & theme
Radii and shadows weren't measured. 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
Best guess: mostly **abstract 3D / gradient art**, some product UI screenshots/mockups (light, warm, Finance). Inferred from element counts, colours and industry — not from the pixels — so open the linked screenshots and match the real style before sourcing anything.
### Slot 1 · 1. Hero, 6. Content, 7. Content → abstract 3D / gradient (uncertain)
- Dark Finance section with a few graphics — typically abstract 3D/gradient art or a product shot. Count: one consistent treatment across these sections. Aspect: 16:9 full-bleed (or 21:9). Look first: [ref 1](https://uidiscovery.com/media/captures/polar/s-01.webp) [ref 2](https://uidiscovery.com/media/captures/polar/s-06.webp) [ref 3](https://uidiscovery.com/media/captures/polar/s-07.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)
- **Generate** — `Abstract 3D render: soft, matte clay shapes and a smooth gradient in #433a14 and #858585 on a #ffffff background. Lighting: soft natural daylight, airy and high-key; warm tone. Minimal and calm, generous negative space on one side for text. Aspect ratio 16:9. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 2 · 4. Features, 8. Features → product UI (uncertain)
- Finance sections with many image elements — most likely product UI screenshots/mockups plus icons. Count: one consistent treatment across these sections. Aspect: 4:3. Look first: [ref 1](https://uidiscovery.com/media/captures/polar/s-04.webp) [ref 2](https://uidiscovery.com/media/captures/polar/s-08.webp)
- **Stock** — “laptop blank screen minimal desk”: [Unsplash](https://unsplash.com/s/photos/laptop-blank-screen-minimal-desk?orientation=landscape) · [Pexels](https://www.pexels.com/search/laptop%20blank%20screen%20minimal%20desk/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/laptop%20blank%20screen%20minimal%20desk/?orientation=horizontal)
- **Generate** — `Product-shot backdrop for a UI screenshot: smooth light gradient from #ffffff to #ffffff with a soft #433a14 glow behind the centre, subtle floor shadow, empty centre area where a screenshot will be placed. Lighting: soft natural daylight, airy and high-key. Aspect ratio 4:3. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people. No UI elements.`
- Build the UI itself in HTML/CSS with realistic sample data from YOUR product (or screenshot your real app). Don't generate UI as an image and don't reuse the reference's screenshots. Stock/AI is only for the backdrop or device frame.
- **No imagery (type-led)** — 2. Features, 3. Content, 5. 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.
### 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:
- **photography** — generate `Photograph: person paying with phone. Composition: wide shot, subject off-centre to one side, generous clean negative space for the headline. Lighting: soft natural daylight, airy and high-key. Warm colour grade that sits on #090909, #433a14, #ffffff. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 16:9. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“person paying with phone” on Unsplash](https://unsplash.com/s/photos/person-paying-with-phone?orientation=landscape) (same query works on Pexels/Pixabay)
- **illustration** — generate `Flat vector illustration: person paying with phone, friendly simplified shapes, limited palette of #090909, #433a14, #ffffff plus one soft neutral, plenty of empty background, consistent line weight, warm mood. Aspect ratio 16:9. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“finance flat illustration” on Unsplash](https://unsplash.com/s/photos/finance-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).
