Marshton

A light style preset for a consumer brand store, near-monochrome and restrained in character. Its look rests on 600-weight display type up to 140px, short uppercase labels with open tracking and a monochrome palette on a cool light gray canvas. Use it as a complete starting point: tokens, type scale, component specs, page rhythm and guardrails are all included.

Type scale

Corners and shadows

• nav: 2.2px
• cards: 0px
• images: 32px
• inputs: 5px
• buttons: 5px
• shadow-1: rgba(0, 0, 0, 0.05) 0px 10px 15px -3px

Spacing and imagery

comfortable density on a 4px base unit; container 1200px; section gap 36px-64px; card padding 20px; element gap 18px-20px; radii nav 2.2px, cards 0px, images 32px, inputs 5px, buttons 5px; 1 shadow level

Photography, product screenshots, illustration, 3d renders. Use placeholder or generated imagery only; partner marks are neutral placeholders in the muted text color. Product views sit in framed panels with the card radius. Photography is shown under a scrim wherever text overlaps it. Icons are outline style at 20-24px in the text or muted color.

Layout

1. top navigation: wordmark left, 4-6 text links, primary action right; collapses to a menu sheet under 768px
2. full-bleed hero with media behind a scrim and the headline anchored lower left
3. feature grid of icon, title and two-line description cells (3-4 columns desktop, 1 column mobile)
4. alternating two-column text-and-visual blocks
5. metrics band with three or four large figures and captions
6. row of placeholder partner marks in a single muted tone (wraps to two rows on mobile)
7. large framed product view on a tinted surface
8. footer with grouped link columns, legal line and social icons
9. content sits in a 1200px centered container with 24px side padding (16px on mobile)
10. sections are separated by 36px-64px of vertical space on desktop, roughly half that on mobile

Patterns

• hero
• feature grid of icon, title and two-line description cells (3-4 columns desktop, 1 column mobile)
• alternating two-column text-and-visual blocks
• metrics band with three or four large figures and captions
• row of placeholder partner marks in a single muted tone (wraps to two rows on mobile)
• large framed product view on a tinted surface

Components

• primary button: fill #ffffff, label #0a0a0a; type 14px/500; uppercase with at least 0.05em tracking; underlined
• primary button (variant 2): fill #ffffff, label #0a0a0a; 5px radius; uppercase with at least 0.05em tracking
• hero block: follows the shared tokens
• feature card: colors: primary action label #0a0a0a, surface #ffffff; 32px radius; no shadow
• hero block (variant 2): colors: surface #ffffff, canvas #e5e7eb
• logo row: colors: surface #ffffff, primary action label #0a0a0a
• product frame: no shadow
• text link: colors: primary action label #0a0a0a, surface #ffffff; uppercase with at least 0.05em tracking
• pill badge: colors: primary action label #0a0a0a; uppercase with at least 0.05em tracking; sticky
• content card: follows the shared tokens

Interactions and states

• opacity and color transitions only, 150ms ease-out
• every interactive element shows a 2px #000000 focus ring with 2px offset
• primary action darkens or lightens by one step on hover and keeps its label color
• navigation collapses to a full-height menu sheet under 768px, trapping focus while open
• all motion is disabled under prefers-reduced-motion
• images show a surface-colored placeholder until loaded, with alt text if they fail
• forms: inline validation, disabled submit while sending, success message and retryable error
• mobile menu open and closed states
• hover, focus-visible, active and disabled states for every button style
• reduced-motion variant with no transitions beyond opacity
• out-of-stock product tile with a disabled add button and 'Notify me' alternative
• cart count badge updates after add

Guardrails

Experience

• Keep one primary action style (#ffffff fill, #0a0a0a label) and use it once per view; secondary actions stay outlined or text-only.
• Use the 5px control radius consistently; do not mix in pill shapes.
• Limit headline sizes to the type scale; the 140px display size appears once per page, in the hero.
• Partner and customer marks are placeholders in one muted tone; never use real company logos.
• Keep copy short and concrete: one idea per section, with a heading that states the benefit.

Accessibility

• Text, links, focus rings and input borders use only the verified pairs listed in contrast checks.
• Focus ring: 2px solid #000000 with 2px offset on every interactive element.
• Body text is 16px or larger at 1.5 line height; nothing is smaller than 12px.
• Decorative colors (dividers and supporting accents) never carry text or the only signal of state.
• Uppercase labels stay short, use at least 0.05em tracking and keep sentence-case text in the HTML source.
• Text over photos or gradients sits on a scrim that keeps it at 4.5:1 against the lightest area.
• Respect prefers-reduced-motion; no parallax or autoplay video without a pause control.

Security

• Validate every form with a shared zod schema on the client and again in the edge function; reject unknown fields.
• Rate-limit form endpoints per IP and add a honeypot field; store leads in a Supabase table with RLS allowing insert only for anonymous users and select only for staff.
• Set a strict Content-Security-Policy, self-host fonts and icons, and avoid third-party scripts beyond privacy-friendly analytics.
• Open external links with rel="noopener noreferrer" and never put secrets or API keys in client code.
• Checkout goes through a hosted payment provider; the site never handles card data, and prices are re-validated on the server.

Build prompt

The rules every style in the gallery assumes, then this style’s own ten sections, from goal to guardrails. A build in the style also gets its tokens as a file, so the colors and type above are exact.

Copy the rules and build prompt

### How to use these prompts
Paste an entry'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
- Enable Row Level Security on every table before inserting data. Default-deny, then add the narrowest policies the feature needs (for a lead form: insert-only for anonymous users, select for a staff role).
- Store roles in a separate table checked by a security-definer function, never in a user-editable profile field.
- 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 carousels and drag interactions keyboard and button alternatives, and never auto-advance them.
- Build mobile-first and test at 375px, 768px and 1280px.

### Content guardrails
- Use original copy, fictional sample data and placeholder or generated imagery. Do not reuse another product's name, logo, screenshots or marketing text.
- Partner and customer logo rows use neutral placeholder marks. Label demo testimonials and metrics as samples. Collect the minimum personal data a form needs.

### Style preset baseline
- Treat the entry's palette, type scale, radii, spacing and shadows as the complete token set. Do not introduce new colors; derive hover and pressed states by moving one step lighter or darker within the same hue, then re-check contrast.
- Colors marked decorative (dividers, supporting accents) never sit behind text and never carry meaning on their own.
- Fonts are open Google Fonts chosen to match the observed letterforms. Self-host them with `font-display: swap` and keep to the listed weights.
- Keep the signature moves listed for the entry, and keep everything else quiet so they stay recognizable.
- One primary action style per view. Secondary actions are outlined or text-only, and links are distinguishable by more than color (underline or weight).

### Goal
Build a responsive light-theme marketing site for a fictional consumer brand store in the "Marshton" style: near-monochrome and restrained, with 600-weight display type up to 140px, short uppercase labels with open tracking, small 5px corners on controls. Use invented copy and placeholder imagery throughout.

### Stack
React 18 + Vite, TypeScript, Tailwind CSS, shadcn/ui (Radix), lucide-react, TanStack Query, zod, Supabase (form submissions only). Design tokens live as CSS variables and are mapped into the Tailwind theme.

### Pages & layout
Home page sections, in order:
- top navigation: wordmark left, 4-6 text links, primary action right; collapses to a menu sheet under 768px
- full-bleed hero with media behind a scrim and the headline anchored lower left
- feature grid of icon, title and two-line description cells (3-4 columns desktop, 1 column mobile)
- alternating two-column text-and-visual blocks
- metrics band with three or four large figures and captions
- row of placeholder partner marks in a single muted tone (wraps to two rows on mobile)
- large framed product view on a tinted surface
- footer with grouped link columns, legal line and social icons
- content sits in a 1200px centered container with 24px side padding (16px on mobile)
- sections are separated by 36px-64px of vertical space on desktop, roughly half that on mobile
Also build a simple contact page with a lead form and a 404 page in the same style. Test at 375px, 768px and 1280px.

### Data & state
Content comes from typed local collections: Feature{icon, title, body}, Product{slug, name, price, imageUrl, alt, inStock, swatches[]}, Metric{value, label}, PartnerMark{label, placeholderSvg}, Lead{email, name?, message?, createdAt}. The lead form posts to a Supabase edge function. Handle these states:
- images show a surface-colored placeholder until loaded, with alt text if they fail
- forms: inline validation, disabled submit while sending, success message and retryable error
- mobile menu open and closed states
- hover, focus-visible, active and disabled states for every button style
- reduced-motion variant with no transitions beyond opacity
- out-of-stock product tile with a disabled add button and 'Notify me' alternative
- cart count badge updates after add

### Accessibility

- Images in AVIF/WebP with explicit width and height, lazy-loaded below the fold; preload the hero image and the display font only.
- One h1 per page, descriptive titles and meta descriptions, Open Graph tags with a generated preview image, and a sitemap.
- Target Lighthouse 95+ for performance, accessibility, best practices and SEO.

### Guardrails
- Keep one primary action style (#ffffff fill, #0a0a0a label) and use it once per view; secondary actions stay outlined or text-only.
- Use the 5px control radius consistently; do not mix in pill shapes.
- Limit headline sizes to the type scale; the 140px display size appears once per page, in the hero.
- Partner and customer marks are placeholders in one muted tone; never use real company logos.
- Keep copy short and concrete: one idea per section, with a heading that states the benefit.
Acceptance criteria:
- Every color in the build comes from the tokens above and every text pair matches a verified contrast pair.
- The page works with keyboard only, shows a visible focus ring everywhere and passes an automated axe check with no violations.
- No real brand names, logos, product screenshots or copied marketing text appear anywhere.
- Layout holds at 375px with no horizontal scrolling.
