## Goal
Build an original features section for **[the user's brand]**. Its job: explain the key benefits, grouped so each can be scanned in seconds.
## Originality rules
- Never reuse Otsuka Air'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: section title over a grid or alternating rows of benefit items. Tall, ≈1.6 screens (1468px at 1440), own light band #ffffff; 2 image/graphics; no interactive controls.
- Content slots: Section title (~6 words, like the reference); 2 items: icon or visual + short title + 1–2 line description.
- Reference headline (tone/length only — never reuse): “/ A b o u t”
- Responsive: stack columns below 768px keeping the order heading → body → action → visual; test at 390 / 768 / 1440px.
## Design tokens
- Colour: section background `#ffffff`, text `#ffffff` (1.0:1), accent `#00a852` (3.1:1), surface `#111312`, muted `#ffffff`. Keep the mood; swap the accent for the user's brand colour.
- Type: headings **Inter** (stand-in for system sans-serif), body **Inter** (stand-in for system sans-serif).
- Shape: On dark, separate layers with 1px borders at ~8–12% white and soft glows instead of drop shadows; expressive layout and motion are part of the appeal — study the scroll video, but keep motion subtle and respect prefers-reduced-motion. Read exact corner radius, border and shadow treatment from the screenshots.

## Imagery
Best guess: mostly **photography** (dark, natural, earthy, Design & Agency). 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 · Features → photography
- Design & Agency references lean on photography. Count: a set of ~2 in one consistent style. Aspect: 4:3. Look first: [ref 1](https://uidiscovery.com/media/captures/otsuka-air/ps-01-03.webp)
- **Stock** — “design studio workspace dark”: [Unsplash](https://unsplash.com/s/photos/design-studio-workspace-dark?orientation=landscape) · [Pexels](https://www.pexels.com/search/design%20studio%20workspace%20dark/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/design%20studio%20workspace%20dark/?orientation=horizontal)
- **Generate** — `Photograph: design studio workspace. Composition: tight crop, identical framing and background across the whole set. Lighting: low-key, moody directional light with deep shadows. Natural, earthy colour grade that sits on #ffffff, #00a852, #111312. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 4:3. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### 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:
- **abstract 3D / gradient** — generate `Abstract 3D render: soft, glossy glass-like shapes and a smooth gradient in #00a852 and #ffffff on a #000000 background. Lighting: low-key, moody directional light with deep shadows; natural, earthy 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.`
- **illustration** — generate `Flat vector illustration: design studio workspace, friendly simplified shapes, limited palette of #ffffff, #00a852, #111312 plus one soft neutral, plenty of empty background, consistent line weight, natural, earthy mood. Aspect ratio 16:9. 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.
