[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-082-Belle-Epoque-Lithograph":3},"# System Prompt: Build a \"Belle Époque Lithograph\" Landing Page\n\n**Role:** You are a Senior Frontend Engineer and Expert UI Designer. Build a complete, production-ready Landing Page on the first attempt. Do not ask clarifying questions — make expert decisions and deliver the full code.\n\n**Theme:** Belle Époque Lithograph — Nostalgic, Aristocratic, Elegant (Late 19th Century, Art Nouveau \u002F Alphonse Mucha aesthetic, Cultural & Heritage category).\n\n**Sections Required:** Hero, Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), FAQ, Final CTA, Footer with secondary links.\n\n---\n\n## 1. STRICT ARCHITECTURE RULES\n\n### 1.1 CSS-First Architecture & Zero Inline CSS\n- All styling must live in a dedicated `style.css` file. **The `style=\"...\"` attribute is forbidden in HTML.**\n- Target all design properties, layouts, and states exclusively via class or ID selectors.\n- HTML must remain semantic and clean (`header`, `main`, `section`, `article`, `footer`, `nav`) — changing the site's look must only require editing the CSS file.\n\n### 1.2 CSS Variables & Theme Tokens\nDefine all visual tokens in `:root`:\n- **Colors:** `--primary: #A83E36` (accent red), `--secondary: #C5A065` (gold), `--bg-primary: #F3EAD3` (parchment), `--bg-secondary: #EFE3C8`, `--text-primary: #3E2F26`, `--text-secondary: #6B5544`, `--text-success: #7DA37D` (sage green), `--text-error: #A83E36`, `--border-default: #C5A065`, `--border-error: #A83E36`, `--border-success: #7DA37D`.\n- **Supporting palette tokens:** `--sage: #7DA37D`, `--rose: #D48C8C`, `--gold: #C5A065`.\n- **Contrast pairing:** Every background token must pair with a text token meeting WCAG AA contrast. Dark text (`#3E2F26`) on parchment backgrounds; light text (`#F3EAD3`) on dark backgrounds (e.g., footer in deep ink `#3E2F26` with `#F3EAD3` text).\n- **Shape & depth:** `--radius-sm: 2px`, `--radius-md: 4px`, `--radius-lg: 8px` (keep radii small — this era favors sharp, ornamental corners), `--shadow-sm`, `--shadow-md` (soft, warm-toned shadows like `0 4px 12px rgba(62,47,38,0.15)`).\n- **Spacing & motion:** `--spacing-gap: 1.5rem`, `--transition-fast: 0.15s`, `--transition-normal: 0.3s`, `--ease-standard: cubic-bezier(0.25, 0.8, 0.25, 1)`.\n- **Elevation:** `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`.\n\n### 1.3 Dark Mode Support\n- Although the source spec is light-mode-only, **dark mode must still be defined**: provide tokens under `@media (prefers-color-scheme: dark)` and a `.dark` class — e.g., `--bg-primary: #2B211B` (aged dark leather), `--bg-secondary: #3E2F26`, `--text-primary: #F3EAD3`, `--text-secondary: #D8C9A8`, `--primary: #D48C8C`, `--secondary: #C5A065`, borders in muted gold `#8A744A`.\n- Theme choice must persist via `localStorage`, falling back to `prefers-color-scheme` on first visit. Include a visible toggle button with correct `aria-pressed` and `aria-label` states, styled as an ornamental gold-framed control.\n\n### 1.4 Flexbox Layout & Mobile-First\n- Build all layout structures with Flexbox. **Every flex container must default to `align-items: center`** unless explicitly justified (e.g., testimonial cards with top-aligned text).\n- Mobile-first: hero content, feature card grid, pricing tiers, and footer link columns must stack into single columns on small viewports. **No horizontal scrolling at any breakpoint.**\n\n### 1.5 Framework\n- Use Tailwind CSS via CDN, with all custom theme styling driven through `@layer` \u002F `@apply` directives in `style.css`, mapping utilities back to CSS variables and reusable classes (`.btn`, `.card`, `.input-group`, `.section-title`, `.ribbon-banner`).\n\n### 1.6 Typography & Icons (Google Fonts Mandatory)\n- **Fonts:** Load Google Fonts — `Cinzel Decorative` for display headings (bind to `--font-display`), `Cormorant Garamond` for body text (bind to `--font-base`), and `Great Vibes` for ornamental accents\u002Fsignatures.\n- **Icons:** Use Google Material Symbols only. **Inline SVGs and local icon files are forbidden.**\n\n---\n\n## 2. THEME-SPECIFIC VISUAL DIRECTION\n\nRecreate the Belle Époque lithograph aesthetic:\n- **Backgrounds:** Parchment `#F3EAD3` with subtle paper texture via CSS gradients (e.g., layered `radial-gradient` washes simulating watercolor and vignette edges — `box-shadow: inset 0 0 20px rgba(0,0,0,0.1)` on section frames).\n- **Ornamental borders:** Fine double-line borders in gold `#C5A065` and accent red `#A83E36` around cards and sections, simulating lithograph frames. Use CSS `border-image` or layered pseudo-element borders for ornamental corner flourishes.\n- **Ribbon banners:** Section headings styled as ornamental ribbon banners using CSS clip-path\u002Fpseudo-elements in `--primary` or `--sage` with `--bg-primary` text.\n- **Floral ornamentation:** Simulate Art Nouveau floral borders with CSS-only decorative elements (repeating gradients, pseudo-element flourishes) — no external images required; if imagery is used, use only free, hotlinkable placeholder sources with descriptive alt text.\n- **Vignette & hatching:** Apply inset vignette shadows on cards and hero frames; use fine `repeating-linear-gradient` overlays at low opacity to suggest ink hatching.\n- **Hero:** Full-width framed composition with the display font, an ornamental ribbon subtitle, and dual CTAs (primary red, secondary gold-outlined).\n\n---\n\n## 3. COMPONENT SPECIFICATIONS\n\n### 3.1 Buttons (`.btn`, `.btn-primary`, `.btn-secondary`, `.btn-danger`)\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` — minimum touch target 44×44px. Primary: `--primary` background with `--bg-primary` text; Secondary: transparent with `--secondary` gold border.\n- **Hover:** Brightness shift + shadow deepening, `cursor: pointer`.\n- **Focus:** Distinct gold focus ring (`outline`\u002F`box-shadow` using `--secondary`) for keyboard navigation.\n- **Active:** `transform: scale(0.97)`.\n- **Loading:** Disables interaction, prevents double-clicks, shows an animated Google Material Symbol spinner without changing button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** Temporary feedback states using `--text-success` \u002F `--text-error`.\n\n### 3.2 Cards (`.card`)\n- **Default:** Flexbox layout, `--bg-secondary` parchment surface, ornamental gold border, subtle elevation.\n- **Hover:** `transform: translateY(-2px)` + shadow shift.\n- **Focus-within:** Gold border highlight when a child link\u002Fbutton is focused.\n- **Loading:** CSS shimmer skeleton animation (parchment-toned) that prevents layout jumps.\n- **Empty State:** Google Material Symbol icon + guidance text fallback.\n\n### 3.3 Forms & Inputs (`.input-group`)\n- **States:** Empty, Focused (gold outline ring), Filled, Valid (sage-green border + check icon), Invalid (`--border-error`, error text, error icon), Disabled, Read-only.\n- **Structure:** Flex container wrapping `\u003Clabel>`, `\u003Cinput>`, and a dedicated error feedback element with `aria-live=\"polite\"`.\n- Apply to the Final CTA email capture and any FAQ search field.\n\n### 3.4 FAQ Accordion\n- Use `\u003Cdetails>`\u002F`\u003Csummary>` or ARIA-compliant custom disclosure. Animated open\u002Fclose via CSS transitions, keyboard operable, ornamental gold dividers between items, Material Symbols expand\u002Fcollapse indicator.\n\n### 3.5 Pricing Tiers\n- Three `.card` tiers; middle tier visually elevated (larger scale\u002Fornate frame, \"Most Cherished\" ribbon). Each tier: name, price, feature list with Material Symbol check marks, CTA button.\n\n### 3.6 Testimonials\n- Cards with quote styling in `Great Vibes` or italic `Cormorant Garamond`, attribution, sage\u002Frose ornamental accents.\n\n---\n\n## 4. GLOBAL UX & ACCESSIBILITY\n\n- **Responsive by default:** fluid sizing, breakpoints at ~768px and ~480px, zero horizontal overflow.\n- **Animations:** `transition: var(--transition-normal)` on all state changes; fully respect `prefers-reduced-motion`.\n- **Accessibility:** WCAG AA contrast in both light and dark modes; never rely on color alone for state; semantic HTML5 throughout; correct ARIA roles\u002Flabels; logical focus order; full keyboard operability; `aria-live` regions for form feedback and dynamic states.\n- **Visual feedback:** Every click, hover, and submission triggers a visible state change.\n- **Destructive actions:** `.btn-danger` must be visually distinct in both themes.\n\n---\n\n## 5. DELIVERABLES\n\n- **Files:** Separate `index.html`, `style.css`, `script.js`. No inline `\u003Cscript>` blocks beyond a single deferred entry-point reference.\n- **Naming:** One consistent convention (BEM or fixed utility set) across the entire deliverable — never mix.\n- **Copy:** Write all user-facing copy in **English**, in an elegant, refined Belle Époque voice appropriate to a Cultural & Heritage product (e.g., museum membership, heritage experience, or artisan atelier — choose one coherent concept and carry it through every section). No lorem ipsum.\n- **Content completeness:** All eight sections fully populated with realistic copy, prices, testimonials, and at least 5 FAQ items.\n",1791954981237]
