Tallowmill

An airy, with gradient atmosphere light-theme style for a consumer brand store website. Its look rests on heavy 700-weight display type up to 60px, short uppercase labels with open tracking and a deep blue lead color on a white canvas. Apply it to a marketing site or the public pages of an app; the tokens and component specs carry the identity.

What makes it

• heavy 700-weight display type up to 60px
• short uppercase labels with open tracking
• small 4px corners on controls
• no shadows; depth comes from surface tone steps
• gradient fields used as atmosphere, never behind body text
• contrasting full-width bands to break the page rhythm
• very generous vertical spacing between sections

Colors

Optimistic, light, modern. The white canvas and short uppercase labels with open tracking carry most of the character.

• canvas / primary action label / text on band#ffffff
• surface#fffcef
• text#000000
• muted text#72728d
• divider (decorative) / input border#84849c
• accent / primary action fill / link text / focus ring#25385b
• inverse band#0a0a3a
• supporting accent (decorative), never behind text#a2b0ff
• second supporting accent (decorative), never behind text#3252f4

Every checked pair, measured again

Typefaces

uppercase only for short labels, with at least 0.05em tracking; no text below 12px; weights of 300 or lighter only at 24px and above; fonts are open Google Fonts chosen to match the observed letterforms

Type scale

Corners and shadows

• cards: 8px
• pills: 9999px
• badges: 9999px
• inputs: 4px
• buttons: 4px

No shadows: depth comes from surfaces and lines.

Spacing and imagery

spacious density on a 4px base unit; container 1200px; section gap 80px-100px; card padding 24px-32px; element gap 8px-16px; radii cards 8px, pills 9999px, badges 9999px, inputs 4px, buttons 4px; no shadows

Photography, illustration, data graphics. Use placeholder or generated imagery only; partner marks are neutral placeholders in the muted text color. 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. thin announcement strip with one inline link and a dismiss button
2. top navigation: wordmark left, 4-6 text links, primary action right; collapses to a menu sheet under 768px
3. split hero: headline, lede and two actions on the left, product visual on the right (stacks on mobile)
4. alternating two-column text-and-visual blocks
5. large framed product view on a tinted surface
6. testimonial cards with quote, name and role
7. feature grid of icon, title and two-line description cells (3-4 columns desktop, 1 column mobile)
8. horizontal card rail with previous/next buttons and snap scrolling
9. metrics band with three or four large figures and captions
10. product grid: image, name, price and quick-add, 4 columns desktop / 2 mobile
11. footer with grouped link columns, legal line and social icons
12. content sits in a 1200px centered container with 24px side padding (16px on mobile)
13. sections are separated by 80px-100px of vertical space on desktop, roughly half that on mobile

Components

• primary button: fill #25385b, label #ffffff; 8px radius; padding 12px 24px; 2px border; no shadow; uppercase with at least 0.05em tracking

• diagram: colors: canvas #ffffff; soft shadow
• footer: colors: inverse band #0a0a3a, canvas #ffffff

Interactions and states

• gradient fields drift slowly; paused on hover and under reduced motion
• every interactive element shows a 2px #25385b 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 (#25385b fill, #ffffff label) and use it once per view; secondary actions stay outlined or text-only.
• Use the 4px control radius consistently; do not mix in pill shapes.
• Limit headline sizes to the type scale; the 60px display size appears once per page, in the hero.
• Separate layers with surface tone and hairlines, not shadows.
• Keep gradients to backgrounds and decorative fields; they are never a button or text fill.
• 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 #25385b 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.
• Some observed colors were moved to the nearest passing shade of the same hue; use the palette values here, not lighter originals.

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 "Tallowmill" style: airy, with gradient atmosphere, with heavy 700-weight display type up to 60px, short uppercase labels with open tracking, small 4px corners on controls. Use invented copy and placeholder imagery throughout.

### Stack
React 18 + Vite, TypeScript, Tailwind CSS, shadcn/ui (Radix), lucide-react, TanStack Query, Motion, 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:
- thin announcement strip with one inline link and a dismiss button
- top navigation: wordmark left, 4-6 text links, primary action right; collapses to a menu sheet under 768px
- split hero: headline, lede and two actions on the left, product visual on the right (stacks on mobile)
- alternating two-column text-and-visual blocks
- large framed product view on a tinted surface
- testimonial cards with quote, name and role
- feature grid of icon, title and two-line description cells (3-4 columns desktop, 1 column mobile)
- horizontal card rail with previous/next buttons and snap scrolling
- metrics band with three or four large figures and captions
- product grid: image, name, price and quick-add, 4 columns desktop / 2 mobile
- 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 80px-100px 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}, Testimonial{quote, name, role, avatarUrl}, Product{slug, name, price, imageUrl, alt, inStock, swatches[]}, Metric{value, label}, 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

### Performance & SEO
- Static generation for every content page; ship no JavaScript to sections that do not need it.
- 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 (#25385b fill, #ffffff label) and use it once per view; secondary actions stay outlined or text-only.
- Use the 4px control radius consistently; do not mix in pill shapes.
- Limit headline sizes to the type scale; the 60px display size appears once per page, in the hero.
- Separate layers with surface tone and hairlines, not shadows.
- Keep gradients to backgrounds and decorative fields; they are never a button or text fill.
- 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.
