## Goal
Build an original logo cloud section for **[the user's brand]**. Its job: borrow trust from recognisable customers or partners.
## Originality rules
- Never reuse Mercury Treasury'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]).
## Layout
- Pattern: a single row or wall of monochrome marks with a one-line lead-in. Compact band (365px at 1440), own light band #fbfcfd; 16 image elements (icons, logos, product UI — not 16 photos); no interactive controls.
- Content slots: One-line lead-in (e.g. “Trusted by…”); 6–10 monochrome customer/partner marks (your own, with permission).
- Reference headline (tone/length only — never reuse): “Backed by the best”
- Responsive: stack columns below 768px keeping the order heading → body → action → visual; test at 390 / 768 / 1440px.
## Design tokens
- Colour: section background `#fbfcfd`, text `#edecfb` (1.1:1), accent `#5266eb` (4.6:1), surface `#181623`, muted `#535461`. Keep the mood; swap the accent for the user's brand colour.
- Type: headings **Inter** (stand-in for Arcadia Display), body **Inter** (stand-in for Arcadia).
- Shape: Radii and shadows weren't measured. Read exact corner radius, border and shadow treatment from the screenshots.

## Imagery
Best guess: mostly **typography with little or no imagery** (dark, cool, 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 · Logo cloud → logos
- Logo cloud. Count: 1–3 key visuals; the rest are icons/avatars. Aspect: 4:3. Look first: [ref 1](https://uidiscovery.com/media/captures/mercury-treasury/ps-03-05.webp)
- 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).
### 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: low-key, moody directional light with deep shadows. Cool colour grade that sits on #fbfcfd, #5266eb, #181623. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 3:2. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- **abstract 3D / gradient** — generate `Abstract 3D render: soft, glossy glass-like shapes and a smooth gradient in #5266eb and #535461 on a #272735 background. Lighting: low-key, moody directional light with deep shadows; cool tone. Minimal and calm, generous negative space on one side for text. Aspect ratio 3:2. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- **Licences:** check each stock image's licence page (Unsplash/Pexels licences, Pixabay Content License), credit when asked, avoid logos, brands and identifiable people; check your image model's commercial terms; never reuse the reference's own images or logos.
## 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.
- [ ] Originality: no copied logos, images, illustrations or copy from the reference; every image licensed or generated; credits recorded.
If you use Next.js + Tailwind: one server component for the section, next/image with explicit sizes, next/font for type, Tailwind v4 @theme tokens from the link above.
