Typefaces

Noto Serif Display is a high-contrast, didone-like display serif that looks dramatic at huge sizes, set against the quiet, neutral Instrument Sans for utility text.

• Noto Serif DisplayHeadings: hero up to 256px at 500, -2.5% tracking
• Instrument SansBody: body 16px, 14px uppercase nav

Who it is for

• Premium DTC product founders
• Small-batch makers and craft studios
• Agencies building luxury product microsites
• Brands preparing a physical product launch

Layout

1. Transparent fixed header: serif wordmark left, SHOP / ABOUT centered in small caps, cart count right
2. Full-bleed hero: oversized serif product name (~256px, tight negative tracking) with a secondary glyph, over a black stage
3. Vignetted product photograph rising from darkness beneath the headline
4. Scroll-revealed story blocks: short narrative paragraphs about origin, materials and process
5. Material/spec strip (e.g. CLAY, GLAZE labels with values)
6. Product landing pages with feature reveals and spec panels
7. Product detail page: sticky info column beside a scrolling image gallery (light theme)
8. Shop grid with sold-out badges and hover zoom
9. Asymmetric About page with alternating image alignment; Shipping and Warranty pages; newsletter footer

Palette

Cinematic, hushed, luxurious, crafted, nocturnal. It feels like a gallery at night where a single spot-lit object is the star.

• background#000000
• text#ffffff
• primary/accent (copper)#b67135
• border#2e2e2e
• muted text#a3a3a3
• product skin tone (imagery)#d9a48f

Every checked pair, measured again

As vibld’s tokens

The palette on the 15+ color tokens vibld styles a project with, each text color on the fill it is read on. Marked tokens are solved from the palette, because no swatch held that role at 4.5:1.

Type scale

Display

Noto Serif Display, weight 500, enormous hero sizes (up to 256px) with -2.5% tracking, sentence case

Body

Instrument Sans 16px regular, nav in 14px uppercase with 0.08em tracking

High-contrast didone serif for emotion and luxury, neutral grotesk for utility; the scale jump between them is the whole effect.

Spacing and imagery

Very airy; content centered in a ~1100px stage, sections separated by a full viewport of black; square buttons (0px) with a small .25rem radius on cards.

Single studio product shots on black with a soft radial vignette so the object emerges from darkness; warm skin-toned highlights; lifestyle/usage images on detail pages.

Build prompt

The baseline every prompt in the catalog assumes, then this design’s own ten sections, from goal to guardrails.

Copy the baseline and build prompt

### How to use these prompts
Paste a template's build prompt into your coding agent as the first message. Each prompt names its own stack, tokens and acceptance criteria; the rules below apply to all of them and can be prepended once per project.

### Engineering baseline
- TypeScript strict mode, no `any`, small typed components, feature folders, and one source of truth for design tokens (CSS variables consumed by Tailwind).
- Validate every input with a shared zod schema on the client and again on the server or edge function. Never trust client-side checks alone.
- Show loading, empty and error states for every async view. Surface errors in plain language with a retry, and log details to the console in development only.
- Keep secrets out of the bundle. Only publishable keys (for example a Supabase anon key) belong in client code; service-role keys, API keys and webhooks live in server or edge-function environment variables.

### Data and auth baseline (full-stack templates)
- Enable Row Level Security on every table before inserting data. Default-deny, then add owner-scoped policies (`auth.uid() = user_id`) and explicit role checks for admin views.
- Store roles in a separate table checked by a security-definer function, never in a user-editable profile field.
- Upload files to private storage buckets with size and MIME limits, and serve them through signed URLs.
- Rate-limit public endpoints (forms, auth, AI calls) and add a honeypot field or captcha to anonymous forms.
- Take payments through a hosted checkout and verify webhooks by signature. Never handle raw card data.

### Accessibility and UX baseline
- Target WCAG 2.2 AA: 4.5:1 contrast for normal text and 3:1 for large text, input borders, focus rings and meaningful icons or chart lines. Every palette in this catalog lists its verified pairs; re-check with a contrast tool after any color change.
- Keep body text at 16px or larger with 1.5 line height, nothing below 12px, no light weights under 24px, and uppercase only for short labels.
- Give every interactive element a visible focus ring, full keyboard support, semantic landmarks, labeled form fields, and alt text on meaningful images.
- Respect `prefers-reduced-motion` for every animation. Give drag-and-drop and carousels keyboard and button alternatives.
- Build mobile-first and test at 375px, 768px and 1280px.

### Content guardrails
- Use original copy, fictional sample data and placeholder or licensed imagery. Do not reuse another product's name, logo, screenshots or marketing text.
- Label demo testimonials and metrics as samples. Collect the minimum personal data the feature needs.

### Goal
Build a cinematic product showcase site for a fictional premium maker called **Kilnlight** that sells a handful of hand-finished objects (swap in speakers, ceramics or watches). The audience is design-conscious buyers who want to feel the craft before they see a price. The site must tell a slow, scroll-driven story about one hero product, then lead into a shop grid and rich product pages.

### Stack
React 18 + TypeScript + Vite, Tailwind CSS, shadcn/ui (Radix) for Sheet, Accordion, DropdownMenu and Toast, lucide-react icons. Use Framer Motion (or IntersectionObserver + CSS) for scroll reveals, Embla Carousel for the mobile gallery, Sonner for add-to-cart toasts, React Router for 8 routes. No backend: products live in a typed TS module; cart state in a React context persisted to localStorage.

### Pages & layout
1. **Home (dark)** – transparent fixed header (serif wordmark, SHOP/ABOUT centered in small uppercase, cart count right). Hero: product name set enormous in serif across the width, then a vignetted product photo rising out of black. Below, 3–4 story chapters (origin, material, making) that fade in one at a time, then a material/spec strip and a CTA to the product.
2. **Two product landing pages** – hero, alternating feature reveals, grouped spec panels, care notes, buy CTA.
3. **Product detail (light theme)** – two columns: sticky info (name, price, variant cards, add to cart, accordions for specs/care/shipping) beside a vertically scrolling image gallery.
4. **Shop** – 3-column grid, sold-out badges, hover zoom.
5. **About** – asymmetric rows with images alternating right/left.
6. **Shipping & returns**, **Warranty** – readable long-form pages.
7. Footer with newsletter input and small links.

### Design system
- Dark tokens: `--background: #000000`, `--foreground: #ffffff`, `--primary: #b67135` (copper), `--border: #2e2e2e` (decorative dividers), `--input-border: #737373`, `--primary-foreground: #000000`, `--muted-foreground: #a3a3a3`. Light pages: `--background: #f7f4ef`, `--foreground: #141414`.
- Fonts: Noto Serif Display (500) for display, Instrument Sans for body. Scale: 12 / 14 / 16 / 20 / 32 / 56 / 96 / clamp(96px, 18vw, 256px); display tracking -0.025em.
- Spacing on an 8px grid; sections separated by 160–240px on desktop. Radius: 0 for buttons, 4px for cards. No shadows on dark; one soft shadow on light cards.
- Motion: reveals 800ms `cubic-bezier(0.22,1,0.36,1)` with 60ms stagger; image zoom 700ms ease-out to scale 1.05.

### Components & interactions
Header (default / scrolled with blur backdrop), mobile full-screen menu (open/close, focus trapped), variant card (default/hover/selected/unavailable), add-to-cart button (default/hover/loading/disabled when sold out), sold-out badge, spec accordion, gallery (keyboard arrows on mobile carousel), newsletter form (idle/submitting/success/error), toast on cart add, empty cart state in the cart sheet.

### Data & state
`Product{slug, name, tagline, price, images[], variants[], specs[{group,label,value}], care[], soldOut}`; `Variant{id, label, swatch, available}`; `CartItem{productId, variantId, qty}`. Seed 6 fictional products with invented names and plausible specs; use placeholder photography of objects on dark backdrops.

### Accessibility
White on black (21:1) and copper `#b67135` on black (5.4:1) pass AA for text. On light pages copper text darkens to `#8a5226` (5.8:1 on `#f7f4ef`). Inputs use `--input-border: #737373`; `#2e2e2e` is decorative. Content hidden before reveal must still be in the DOM and announced; respect `prefers-reduced-motion` by showing everything immediately. Visible 2px copper focus rings. Hero heading stays a real `<h1>` even at giant size. Every product image gets descriptive alt text. Mobile menu is a dialog with Escape to close.
Verified contrast: body text on dark background #ffffff on #000000 = 21.0:1; muted text on dark background #a3a3a3 on #000000 = 8.33:1; copper accent text on dark background #b67135 on #000000 = 5.4:1; button label on copper primary #000000 on #b67135 = 5.4:1; copper focus ring on dark background #b67135 on #000000 = 5.4:1; input border on dark background #737373 on #000000 = 4.43:1; body text on light product pages #141414 on #f7f4ef = 16.79:1.

### Security
Static site: newsletter form validated with zod (email format, length), honeypot field and a simple client throttle; if you post to a serverless endpoint, validate again there. No API keys in client code. External social links use `rel="noopener noreferrer"`. Checkout, if added later, must go through a hosted checkout, never raw card fields.

### Performance & SEO
Preload the hero image with explicit width/height and `fetchpriority="high"`; lazy-load everything else, serve AVIF/WebP. Route-level code splitting. Per-page title, meta description and Open Graph image; Product JSON-LD on detail pages. Target Lighthouse 90+ on mobile.

### Guardrails
- Original copy and placeholder imagery only; no real brand names, logos or trademarks.
- No invented testimonials presented as real customers.
- Keep components small and typed; no `any`; surface errors visibly.
- Done when: all 8 routes render; scroll reveals work and degrade with reduced motion; the sticky info column stays pinned while the gallery scrolls; cart count updates and persists across reloads; Lighthouse accessibility is 95+.
